Water Supply
The Public Water Supplies (Scotland) Regulations 2014
Made 2014
Coming into force 1st January 2015

The Scottish Ministers make the following Regulations in exercise of the powers conferred by sections 76A(3)(b), 76B, 76F(5) and (6), 76J, 101(1) and (1A) and 109(1) of the Water (Scotland) Act 1980, section 56(1) and (2) of the Finance  Act  1973 and section 2(2) of, and paragraph 1A of Schedule 2 to, the European Communities Act 1972 and of all other powers enabling them to do so.
1980 c.45. Sections 76A(3)(b), 76B, 76F(5) and (6) and 76J were inserted by section 168 of, and Schedule 22 to, the Water Act 1989 (c.15). Section 76A(3)(b) was amended by paragraph 49 of schedule 6 to the Water Industry (Scotland) Act 2002 (asp 3). Section 76B was amended by section 56(2) of the Food Safety Act 1990 (c.16) and paragraph 50 of schedule 6 to the Water Industry (Scotland) Act 2002. Section 76F(5) and (6) was amended by paragraph 119(42) of Schedule 13 to the Local Government etc. (Scotland) Act 1994 (c.39). Section 76J was amended by paragraph 119(45) of Schedule 13 to the Local Government etc. (Scotland) Act 1994 (c.39). Section 101(1A) was inserted by section 27(1) of, and paragraph 9(5) of Schedule 10 to, the Natural Heritage (Scotland) Act 1991 (c.28). The definition of “prescribed” in section 109(1) was amended by paragraph 38(f) of Schedule 11 to the Local Government Finance Act 1992 (c.14).
1973 c.51. Section 56(1) of the Finance  Act  1973 was amended by S.I. 2011/1043. The powers in section 56(1) and (2) of that Act are exercised in relation to regulation 33(12) to enable the Scottish Ministers to determine the amount of any charge to be paid. The reference to a Government department in section 56(1) of that Act is to be read as a reference to the Scottish Administration by virtue of article 2(2) of S.I. 1999/1820 and the functions of the Minister were, so far as within devolved competence, transferred to the Scottish Ministers by virtue of section 53 of the Scotland Act 1998 (c.46). The requirement to obtain the consent of the Treasury was removed by section 55 of the Scotland Act 1998.
1972 c.68. Section 2(2) was amended by the Scotland Act 1998 (c.46) (“the 1998 Act”), Schedule 8, paragraph 15(3) (which was amended by section 27(4) of the Legislative and Regulatory Reform Act 2006 (c.51) (“the 2006 Act”)). Section 2(2) was also amended by section 27(1)(a) of the 2006 Act and by the European Union (Amendment) Act 2008 (c.7) (“the 2008 Act”), Schedule, Part 1. Paragraph 1A of Schedule 2 was inserted by the 2006 Act, section 28 and amended by the 2008 Act, Schedule, Part 1. The functions conferred upon the Minister of the Crown under section 2(2), insofar as within devolved competence, were transferred to the Scottish Ministers by virtue of section 53 of the 1998 Act. Section 2(2) is cited to enable provision in relation to the matters listed in the penultimate paragraph of the explanatory note to these Regulations.
The powers to make these Regulations are exercised together by virtue of section 33(2) of the Interpretation and Legislative Reform (Scotland) Act 2010 (asp 10). These Regulations are subject to the affirmative procedure by virtue of section 33(3) of that Act.
These Regulations make provision for a purpose mentioned in section 2(2) of the European Communities Act 1972, and it appears to the Scottish Ministers that it is expedient for the reference in regulation 33(2) to Directive 98/34/EC of the European Parliament and of the Council laying down a procedure for the provision of information in the field of technical standards and regulations and of rules on Information Society services to be construed as a reference to that instrument as amended from time to time.
OJ L 204, 21.7.1998, p.37, amended by Directive 98/48/EC (OJ L 217, 5.8.1998, p.18), Council Directive 2006/96/EC (OJ L 363, 20.12.2006, p 81) and Regulation (EU) No 1025/2012 (OJ L 316, 14.11.2012, p.12).
There has been a consultation as required by Article 9 of Regulation (EC) No 178/2002 of the European Parliament and of the Council laying down the general principles and requirements of food law, establishing the European Food Safety Authority and laying down procedures in matters of food safety.
OJ L 31, 1.2.2002, p.1, to which there are no relevant amendments to Article 9.
In accordance with paragraphs 2, 2A(1), (2)(a) and (3)(a) in Schedule 2 to, the European Communities Act 1972, a draft of this instrument has been laid before and approved by resolution of the Scottish Parliament.
Paragraphs 2(2) and 2A(1), (2)(a) and (3)(a) have been modified by paragraph 5 of schedule 3 to the Interpretation and Legislative Reform (Scotland) Act 2010 (asp 10).

PART 2 WATER SUPPLY ZONES

3 Water supply zones
1 Before the beginning of each year in which it intends to supply water for human consumption purposes, Scottish Water must designate and name the areas within its area of supply that are to be water supply zones for that year.
2 A water supply zone may not comprise an area whose population immediately before the beginning of the year in question is estimated by Scottish Water to exceed 100,000.
3 A water supply zone may not comprise an area with significant variations in water quality.
4 Scottish Water may not vary a designation under paragraph (1) after the beginning of the year in relation to which the designation has effect.

PART 3 WHOLESOMENESS OF PUBLIC WATER SUPPLIES

4 Wholesomeness: public water supplies
1 Water supplied by Scottish Water for human consumption purposes is, subject to paragraphs (3) and (4), to be regarded as wholesome for the purposes of Part VIA of the 1980 Act (as it applies to water supplied for such purposes) only if the requirements in paragraph (2) are satisfied.
2 The requirements are that the water—
(a) does not contain—
(i) any micro-organism;
(ii) any substance; or
(iii) any parasite,
at a concentration or value which would (whether in conjunction with another parameter in the water or otherwise) constitute a potential danger to human health;
(b) does not contain a parameter in Table A or Table B at a concentration or value in excess of or, as the case may be, less than the prescribed concentration or value for that parameter; and
(c) satisfies the formula “[nitrate]/50 + [nitrite]/3 ≤ 1”, where the square brackets signify the concentrations in mg/l for nitrate (NO3) and nitrite (NO2) respectively.
3 The point (“point of compliance”) at which the requirements in paragraph (2), in so far as they relate to a parameter in Table A or Table B, are to be complied with is—
(a) in the case of water supplied from a tanker, the point at which the water emerges from the tanker;
(b) in the case of water supplied in bottles or containers, the point at which the water first emerges from any bottle or container collected from a local distribution point; and
(c) in any other case, the point or points specified for that parameter in Table A or Table B.
4 Water that—
(a) is transferred from a service reservoir;
(b) is intended for supply by Scottish Water for human consumption purposes; and
(c) exceeds the prescribed concentration or value for coliform bacteria (item 3) in Table A,
is not to be regarded as unwholesome for the purposes of Part VIA of the 1980 Act if, in at least 95% of samples taken in any year in which the reservoir in question is in use, coliforms were absent.

PART 4 MONITORING OF PUBLIC WATER SUPPLIES

5 Application and interpretation
1 This Part applies only in relation to the supply of water for human consumption purposes by Scottish Water in the performance of its duties under Part VIA of the 1980 Act.
2 In this Part—
“audit monitoring” means monitoring for the purpose of obtaining information from which it may be established, as regards a parameter in Table A, Table B or Table C, whether the concentration, value or state of the parameter in water supplied for human consumption purposes complies with the prescribed concentration or value for that parameter (at the point of compliance or, as the case may be, point of monitoring); and
“check monitoring” means monitoring for the purpose of obtaining information as to—
(a) the organoleptic and microbiological quality of water; and
(b) the effectiveness of any drinking-water treatment used (particularly of disinfection),
for the purpose of determining, as regards a parameter (in Table A, Table B or Table C) listed in Table 1, whether the concentration, value or state of the parameter in water supplied for human consumption purposes complies with the prescribed concentration or value for that parameter (at the point of compliance or, as the case may be, point of monitoring).

6 Monitoring: general provisions
1 For the purposes specified in paragraph (2), Scottish Water must, for each water supply zone—
(a) take or have taken; and
(b) analyse or have analysed,
not less than the number of samples of water required by this Part.
2 The purposes are—
(a) determining whether, within each water supply zone, water to which this Part applies satisfies the wholesomeness requirements of Part 3; and
(b) establishing the quality of water to be supplied to each water supply zone.
3 Subject to paragraph (4) and regulation 13 (water supplied by tanker), Scottish Water must carry out audit monitoring in relation to each parameter in Table A, Table B and Table C.
4 Scottish Water must carry out check monitoring (instead of audit monitoring)—
(a) in relation to each parameter in Table 1 for which there is no entry in column (3); and
(b) in relation to each parameter in Table 1 for which there is an entry in column (3) but only when the circumstances in that entry apply.
5 In the application of paragraph (4)(b) to—
(a) aluminium (item 27) in Table B;
(b) iron (item 29) in Table B;
(c) manganese (item 30) in Table B; or
(d) Clostridium perfringens (item 3) in Table C,
a supply of water which consists of both groundwater and surface water is to be treated as if it were a supply which consists only of surface water.
6 The following parameters must be monitored in such manner as the Scottish Ministers may, by notice given to Scottish Water, specify—
(a) copper (item 10) in Table B;
(b) lead (item 15) in Table B;
(c) nickel (item 17) in Table B;
(d) subject to paragraph (7)(a), indicative dose (item 14) in Table C; and
(e) subject to paragraph (7)(b), tritium (item 15) in Table C.
7 The Scottish Ministers must, by notice given to Scottish Water, inform it that indicative dose (item 14) or, as the case may be, tritium (item 15) in Table C need not be monitored in relation to a water supply zone if they are satisfied that the water supplied to that zone for human consumption purposes—
(a) in the case of indicative dose, gives rise to a calculated indicative dose that is, in the opinion of the Scottish Ministers, significantly below the prescribed concentration or value for that parameter; or
(b) in the case of tritium, contains levels of tritium that are, in the opinion of the Scottish Ministers, significantly below the prescribed concentration or value for that parameter.
8 The Scottish Ministers must, by notice given to Scottish Water, withdraw a notice given under paragraph (7)—
(a) in relation to indicative dose, if they are no longer of the opinion that water supplied to the zone for human consumption purposes gives rise to a calculated indicative dose that is significantly below the prescribed concentration or value for that parameter; and
(b) in relation to tritium, if they are no longer of the opinion that water supplied to the zone for human consumption purposes contains levels of tritium that are significantly below the prescribed concentration or value for that parameter.
9 Where Scottish Water receives a notice under paragraph (8), it must monitor the indicative dose or, as the case may be, tritium in accordance with any notice in relation to that parameter having effect for the time being under paragraph (6)(d) or, as the case may be, paragraph (6)(e).

7 Random samples from consumers’ taps
1 Where a sample of water must, under this Part, be taken from a consumer’s tap within a water supply zone, the tap must be selected at random unless the Scottish Ministers otherwise direct (in exercise of powers under section 56(3) of the Water Industry (Scotland) Act 2002).
2002 asp 3.
2 Paragraph (1) does not apply if the sample is to be taken instead from an alternative point within the same water supply zone which is authorised for that purpose under regulation 8.

8 Authorisation of samples from alternative points
1 The Scottish Ministers may in relation to any parameter in Table A, Table B or Table C, on the application in writing (or in electronic form) of Scottish Water, authorise the use (for the purposes of regulation 6) of samples taken for a water supply zone otherwise than from a sampling point, and any such authorisation may extend to all samples in relation to that parameter or to such number or proportion of those samples as is specified in the authorisation.
2 The Scottish Ministers must not grant an authorisation under paragraph (1) unless they are satisfied that analysis of samples taken from any point to be so authorised (“supply point”) will produce data in respect of the parameter in question which are unlikely to differ in any material respect from the data that would be produced in respect of that parameter from analysis of samples obtained from any sampling point within the same water supply zone.
3 Subject to paragraph (4), the Scottish Ministers may at any time modify or revoke an authorisation under paragraph (1).
4 Unless it appears to the Scottish Ministers that an immediate modification or revocation of an authorisation under paragraph (1) is required in the interests of public health, they must not modify or revoke such an authorisation without giving to Scottish Water at least 6 weeks’ notice of their intention to modify or revoke.
5 Scottish Water must notify the Scottish Ministers as soon as it has reasonable grounds for believing that an analysis of samples taken for a water supply zone from a supply point would produce data in respect of the parameter in question which would differ in a material respect from the data produced by an analysis of samples taken from any sampling point within that zone.
6 The Scottish Ministers must, on being notified under paragraph (5) and without the need for prior notice to Scottish Water, revoke the authorisation.
7 In this regulation, “sampling point” means—
(a) in the case of water supplied from a distribution network, a consumer’s tap; and
(b) in the case of water supplied from a tanker, the point at which it emerges from the tanker.

9 Numbers of samples
1 Subject to regulations 11 and 12 and paragraph (2), in each year Scottish Water must take, or cause to be taken (for each water supply zone)—
(a) from sampling points; or
(b) to the extent authorised under regulation 8, from alternative supply points,
the standard number of samples for each parameter in Table 2 or, as the case may be, Table 3.
2 Where, in respect of a parameter in Table A, Table B or Table C that is subject to check monitoring (in accordance with regulation 6(4) as read with the Tables 1 to 4 in Schedule 2)—
(a) Scottish Water considers that the quality of water supplied by it to a water supply zone is unlikely to deteriorate; and
(b) the conditions in paragraph (3) are met,
the number of samples to be taken in the following year for that parameter may be the reduced number of samples for that parameter in Table 2 or, as the case may be, Table 3.
3 The conditions are that in each of two successive years—
(a) the results of samples taken in accordance with these Regulations show no significant variation; and
(b) if the parameter in question is—
(i) Escherichia coli (item 2) in Table A, it has not exceeded 0;
(ii) Clostridium perfringens (item 3) in Table C, it has not exceeded 0;
(iii) coliform bacteria (item 4) in Table C, it has not exceeded 0;
(iv) colony count (item 5) in Table C, it has shown no abnormal change;
(v) hydrogen ion (item 8) in Table C, it has maintained a pH value that is not less than 6.5 and not more than 9.5;
(vi) total organic carbon (item 12) in Table C, it has shown no abnormal change; or
(vii) any other parameter, it has maintained a concentration or value that is significantly lower than the prescribed concentration or value.
4 Samples required to be taken by this regulation must be taken at regular intervals.
5 In this regulation—
(a) “sampling points” is to be construed in accordance with regulation 8(7);
(b) “the reduced number” means—
(i) for sampling points, the applicable number in column (4) of Table 2; and
(ii) for a supply point, the applicable number in column (4) of Table 3; and
(c) “the standard number” means—
(i) for sampling points, the applicable number in column (5) of Table 2; and
(ii) for a supply point, the applicable number in column (5) of Table 3.

10 Additional sampling
As soon as Scottish Water has reasonable grounds for believing that any element, organism or substance (other than residual disinfectant or a parameter in Table A, Table B or Table C), whether alone or in combination with any other such parameter or any other element, organism or substance, may cause the supply within a water supply zone to be a supply which does not satisfy the requirements of Part 3, it must take, or cause to be taken, sufficient samples from water within that zone (whether from a service reservoir, a treatment works or otherwise) in respect of that element, organism or substance to establish whether that water is wholesome.

11 Sampling at treatment works
1 Subject to paragraphs (2) and (3), in each year Scottish Water must take, or cause to be taken, from the point at which water leaves each treatment works which serves a water supply zone, the standard number of samples for analysis to determine—
(a) the concentration of residual disinfectant;
(b) whether water leaving the treatment works complies with the prescribed concentration or value for—
(i) coliform bacteria (item 3) in Table A;
(ii) Escherichia coli (item 4) in Table A; and
(iii) nitrite (item 19) in Table B (where the point of compliance is a treatment works);
(iv) colony count (item 5) in Table C; and
(v) turbidity (item 13) in Table C.
2 Where, in each of two successive years, the analysis of samples taken in accordance with these Regulations establishes that—
(a) for coliform bacteria, Escherichia coli, nitrite or turbidity (as the case may be), the prescribed concentration or value has not been exceeded; or
(b) for colony count, there has been no significant increase in the count,
the number of samples to be taken in the following year in respect of that parameter from the point at which water leaves that treatment works may, subject to paragraph (3), be the reduced number.
3 For coliform bacteria or, as the case may be, Escherichia coli, the reduced number of samples may be taken only if Scottish Water considers that—
(a) there is no foreseeable risk that the supply will exceed the prescribed concentration or value for that parameter; or
(b) the treatment works is designed to secure that, in the event of a failure of the disinfection process, water that has not been disinfected cannot enter the supply.
4 Samples required to be taken by this regulation must be taken at regular intervals.
5 Where a treatment works is in use for only part of a year, the number of samples that must, under this regulation, be taken during that year (from the point at which water leaves the works) may be reduced in proportion to the number of days in that year that the works has not been in use.
6 In this regulation—
“the reduced number” means the applicable number (if any) in column (4) of Table 4; and
“the standard number” means the applicable number in column (5) of Table 4.

12 Sampling at service reservoirs
Scottish Water must take, or cause to be taken, from each of its service reservoirs in each week in which the service reservoir is in use, one sample for analysis—
(a) for determining the concentration of residual disinfectant;
(b) for testing for compliance with the prescribed concentration and value for—
(i) coliform bacteria (item 3) in Table A; and
(ii) Escherichia coli (item 4) in Table A; and
(c) for determining whether the prescribed concentration or value for colony count (item 5) in Table C (in so far as the point of monitoring is a service reservoir) is complied with.

13 Sampling: water supplied by tanker
1 Where the distribution of water in any part of a water supply zone is by tanker and is (or is likely to be) an intermittent short-term supply, samples of water from each tanker from which the water is distributed must be taken—
(a) 48 hours after the commencement of the distribution from that tanker; and
(b) every 48 hours thereafter until the distribution is discontinued.
2 The first sample taken in relation to each distribution must be analysed for compliance with—
(a) Escherichia coli (item 2) in Table A;
(b) conductivity (item 7) in Table C; and
(c) hydrogen ion (item 8) in Table C.
3 The second and any subsequent samples must be analysed for compliance with every parameter in Table A, Table B and Table C.

14 Sampling: new sources
1 This regulation applies in relation to—
(a) any source of water which has not been used for the supply of water by Scottish Water at any time during the period of 6 months preceding 1st January 2015; and
(b) any source of water which has been so used, but not so used during the period of 6 months preceding the date on which Scottish Water proposes to supply water from it.
2 Scottish Water must—
(a) before it supplies water from a source mentioned in paragraph (1)(a); and
(b) as soon as is reasonably practicable after it has begun to supply water from a source mentioned in paragraph (1)(b),
take, or cause to be taken, in accordance with paragraph (3), such samples of that water as will enable it to establish—
(i) whether water can be supplied from that source without contravening section 76A(1) of the 1980 Act (duties of water authorities with respect to water quality); and
(ii) the treatment necessary to ensure that section 76A(1) of the 1980 Act is complied with in relation to the supply of that water.
3 Samples must be taken—
(a) in the case of a source of water mentioned in paragraph (1)(a), in respect of—
(i) the parameters in Table A, Table B and Table C; and
(ii) any other micro-organism, substance or parasite which may be present in, or any property of, the water which Scottish Water considers has the potential to cause a supply of water (from that source) to contravene section 76A(1) of the 1980 Act; and
(b) in the case of a source mentioned in paragraph (1)(b), in respect of—
(i) enterococci (item 1) in Table A;

(iii) coliform bacteria (item 3) in Table A;
(iv) conductivity (item 7) in Table C;
(v) hydrogen ion (item 8) in Table C;
(vi) turbidity (item 13) in Table C; and
(vii) any other parameter in Table B or Table C in relation to which Scottish Water considers that the concentration or value of that parameter is likely to have altered since the last occasion on which water from that source was analysed.
4 Unless the conditions in paragraph (5) are satisfied, Scottish Water must not supply water for human consumption purposes from a source mentioned in paragraph (1)(a) until a period of one month has elapsed since the day on which Scottish Water complied with regulation 31(1) (as read with regulation 30) with respect to the source.
5 The conditions are that Scottish Water—
(a) must supply water from the source as a matter of urgency in order to prevent an unexpected interruption in a piped supply of water to consumers; and
(b) before the supply is made, has carried out a risk assessment under regulation 30 specifically with respect to the source.
6 For the purposes of paragraph (4) (in so far as it requires compliance with regulation 31(1)) and paragraph (5)(b), regulation 30 applies in relation to each supply of water mentioned in those paragraphs as if “treatment works” includes the source from which the untreated water is supplied.

15 Collection and analysis of samples
1 Scottish Water must ensure, so far as is reasonably practicable, that in taking, handling, transporting, storing and analysing any sample required to be taken for the purposes of this Part, or causing any such sample to be taken, handled, transported, stored and analysed, the appropriate requirements are satisfied.
2 In paragraph (1) “the appropriate requirements” means such of the following requirements as are applicable—
(a) the sample is representative of the quality of the water at the time of sampling;
(b) the sample is not contaminated when being taken;
(c) the sample is kept at such temperature and in such conditions as will secure that there is no material alteration of the concentration or value or specification for the measurement or observation for which the sample is intended;
(d) the sample is analysed as soon as may be after it has been taken—
(i) by or under the supervision of a person who is competent to perform that task; and
(ii) with the use of such equipment as is suitable for the purpose; and
(e) any laboratory at which samples are analysed has a system of analytical quality control that is subjected from time to time to checking by a person who is—
(i) not under the control of either the laboratory or Scottish Water; and
(ii) approved by the Scottish Ministers for that purpose.
3 For the purposes of paragraph (2)(e), “laboratory at which samples are analysed” includes a person who undertakes the analysis of samples for this Part, whether at the time and place where the samples are taken or otherwise.
4 Scottish Water must maintain such records as are sufficient to enable it to establish, in relation to each sample taken for the purposes of this Part, that such of the appropriate requirements as are applicable to that sample have been satisfied.
5 Subject to paragraph (7), for the purpose of establishing (within acceptable limits of deviation and detection) whether a sample contains a parameter in Table A, Table B or Table C at a concentration or value which contravenes the corresponding prescribed concentration or value—
(a) the method of analysis specified in column (3) of Table M1 must be used for determining compliance with the parameter specified in relation to that method in column (2) of that table;
(b) the method of analysis used for determining compliance with a parameter specified in column (2) of Table M2 must be capable, at the time of use—
(i) of measuring concentrations and values equal to the prescribed concentration or value with the trueness and precision specified in relation to that parameter in columns (3) and (4), respectively, of that table; and
(ii) of detecting the parameter at the limit of detection specified in relation to that parameter in column (5) of that table;
(c) the methods of analysis used for—
(i) odour (item 9) in Table C; and
(ii) taste (item 11) in Table C,
must be capable, at the time of use, of measuring values in relation to the prescribed concentration or value with a precision of 1 dilution number at 25°C; and
(d) the method of analysis used for determining compliance with hydrogen ion (item 8) in Table C must be capable, at the time of use, of measuring concentrations equal to the prescribed concentration or value with a trueness of 0.2 pH unit and a precision of 0.2 pH unit.
6 For the purposes of paragraph (5)—
“limit of detection” is to be calculated as—
(a) 3 times the relative within batch standard deviation of a natural sample containing a low concentration of the parameter; or
(b) 5 times the relative within batch standard deviation of a blank sample;
“precision” (the random error) is to be calculated as twice the standard deviation (within a batch and between batches) of the spread of result about the mean; and
“trueness” (the systematic error) is to be calculated as the difference between the mean value of the large number of repeated measurements and the true value.
7 Subject to paragraph (9), the Scottish Ministers may, on the application of any person, authorise, by notice given to Scottish Water, a method of analysis other than that mentioned in paragraph (5)(a) (“the prescribed method”).
8 An application for the purpose of paragraph (7) must be made in writing (or in electronic form acceptable to the Scottish Ministers) and be accompanied by—
(a) a description of the method of analysis; and
(b) the results of the tests carried out to demonstrate the reliability of that method and its equivalence to the prescribed method.
9 The Scottish Ministers must not authorise the use of the method proposed in the application unless they are satisfied that the results obtained by the use of that method are at least as reliable as those produced by the use of the prescribed method.
10 An authorisation under paragraph (7) may be subject to such conditions as the Scottish Ministers think fit.
11 The Scottish Ministers may, by notice given to Scottish Water, revoke an authorisation under paragraph (7) but no such notice is to be given later than 3 months before the date on which the revocation is stated to take effect.

PART 6 INVESTIGATION AND REMEDIAL ACTION

17 Scottish Water to investigate immediately any failure or likely failure
1 Where Scottish Water has reason to believe that water supplied by it for human consumption purposes has failed, is failing, or is likely to fail to—
(a) satisfy a requirement of regulation 4(2); or
(b) meet the prescribed concentration or value for a parameter in Table C,
it must immediately investigate (and take action) to establish the matters in paragraph (2).
2 The matters to be established are—
(a) whether the water has failed, is failing or is likely to fail to—
(i) satisfy a requirement of regulation 4(2); or
(ii) meet the prescribed concentration or value for a parameter in Table C; and
(b) for any such failure or apprehended failure (“the failure”)—
(i) the parameter or other element, organism or substance to which the failure relates;
(ii) the cause and extent of the failure;
(iii) whether the failure is due to a domestic distribution system in premises where water is supplied to the public, or to the maintenance of that system;
(iv) whether the failure is due to a private domestic distribution system, or to the maintenance of that system; and
(v) whether the failure constitutes a potential danger to human health.
3 Where Scottish Water has—
(a) investigated a failure or apprehended failure for the purposes of paragraph (1); and
(b) that investigation establishes that the failure is due to a domestic distribution system in premises where water is supplied to the public, or to the maintenance of that system,
it may recover the expenses reasonably incurred by it (in carrying out that investigation) from the person who owns or is otherwise responsible for that domestic distribution system.

18 Scottish Water to notify immediately any potential danger to human health
1 Where Scottish Water establishes under regulation 17(1) that the failure in question constitutes a potential danger to human health, it must, by notice, immediately notify this to—
(a) the Drinking Water Quality Regulator for Scotland;
(b) the Scottish Ministers;
(c) each local authority for the area in which the potential danger occurs; and
(d) those of its consumers who are likely to be affected by the failure.
2 The notice required by paragraph (1)(d) must inform the consumers—
(a) of the nature of the failure;
(b) that the failure constitutes a potential danger to human health;
(c) of any remedial action taken, or to be taken, by Scottish Water; and
(d) of any action that Scottish Water considers is necessary or desirable for the consumer to take to protect human health.

19 Scottish Water to report on its investigation etc.
1 On completion of the investigation mentioned in regulation 17(1), Scottish Water must, as soon as possible, report the findings of the investigation to—
(a) the Drinking Water Quality Regulator for Scotland;
(b) the Scottish Ministers; and
(c) where the failure in question is due to a domestic distribution system (or to the maintenance of that system) in premises where water is supplied to the public, the local authority for the area in which the premises is located.
2 The report must specify—
(a) the matters in regulation 17(2)(a) and (b);
(b) whether the failure has ceased and, if so, whether it is likely to recur;
(c) any action which Scottish Water considers must be taken—
(i) to restore, as soon as possible, the quality of the water in question so that it satisfies the requirements of regulation 4(2);
(ii) to protect human health until the quality of the water is restored; and
(iii) to minimise the risk of the water failing to satisfy any such requirement; and
(d) any such action taken, or to be taken, by Scottish Water.
3 Where the report specifies that the failure is due to a domestic distribution system (or to the maintenance of that system) in premises where water is supplied to the public, Scottish Water must as soon as possible inform such persons as the Drinking Water Quality Regulator for Scotland or the Scottish Ministers may, by notice given to Scottish Water, specify—
(a) of the cause and extent of the failure;
(b) whether the failure constitutes a potential danger to human health;
(c) of any remedial action taken, or to be taken, by Scottish Water; and
(d) of any action that Scottish Water considers is necessary or desirable for those persons to take to protect human health.

20 Scottish Water to restore water quality
1 Subject to paragraphs (4) and (5), where an investigation under regulation 17(1) establishes that the failure in question is on-going, Scottish Water must as soon as possible—
(a) take such remedial action as is necessary to restore the quality of the water (to which the failure relates) so that it—
(i) satisfies the requirements of regulation 4(2)(b) and (c); and
(ii) meets the prescribed concentration or value for a parameter in Table C; and
(b) where the water fails to satisfy a requirement of regulation 4(2) in relation to—
(i) copper (item 10) in Table B; or
(ii) lead (item 15) in Table B,
take action to modify or replace such of Scottish Water’s pipes and associated fittings as it knows or has reason to believe have the potential for contributing to copper or lead in the water supplied to the premises, so as to eliminate that potential (whether or not copper or lead in those pipes contributed to the failure).
2 Except where it considers that the failure in question is trivial, Scottish Water must inform (in so far as it has not already done so) those of its consumers who are likely to be affected by the failure of any remedial action taken under paragraph (1)(a).
3 For the purposes of securing compliance with paragraph (1)(a), the Drinking Water Quality Regulator for Scotland and the Scottish Ministers must, in the exercise of their enforcement functions, give priority to enforcement action having regard, among other things, to—
(a) the extent to which the prescribed concentration or value for a parameter (in Table A, Table B and Table C) has not been met; and
(b) the potential danger to human health.
4 Where the investigation establishes that the failure in question is due to a domestic distribution system in premises where water is supplied to the public (or to the maintenance of that system), paragraph (1)(a) does not apply in so far as a local authority must, under section 76FB of the 1980 Act, require the person who owns or is otherwise responsible for that system to take any such remedial action as is required by that paragraph.
1980 c.45; section 76FB was inserted by S.S.I. 2010/95 and is amended by regulation 48 of these Regulations.
5 Where the investigation establishes that the failure in question is due to a private domestic distribution system (or to the maintenance of that system) and there is a risk that the water in question is failing or will fail to satisfy a requirement of regulation 4(2)(b) or (c) or meet the prescribed concentration or value for a parameter in Table C, Scottish Water must ensure that—
(a) appropriate measures are taken to reduce or eliminate that risk (such as advising the owner and any occupiers of the premises served by the private domestic distribution system in question of any possible remedial action that they could take); and/or
(b) other measures (such as appropriate treatment techniques) are taken to change the nature or properties of the water before it is supplied so as to reduce or eliminate that risk.

21 Scottish Water to protect human health
1 Subject to paragraph (3), where an investigation under regulation 17(1) establishes that the failure in question is on-going and constitutes a potential danger to human health, Scottish Water must take such action as is necessary to protect human health from that danger (such as isolating anything that appears to be affecting, or may affect, the quality of the water).
2 Scottish Water must decide what action should be taken to comply with paragraph (1), bearing in mind the risks to human health which would be caused by an interruption of the supply or a restriction in the use of water intended for human consumption.
3 Where the investigation establishes that the failure is due to a domestic distribution system in premises where water is supplied to the public (or to the maintenance of that system), paragraph (1) does not apply in so far as a local authority must, under section 76FB of the 1980 Act, require the person who owns or is otherwise responsible for that system to take any such action as is required by that paragraph.
4 Scottish Water must inform (in so far as it has not already done so) those of its consumers who are likely to be affected by the failure of any action taken under paragraph (1).

22 Powers to require further action by Scottish Water
1 Where—
(a) an investigation under regulation 17(1) establishes that the failure in question is due to a failure to satisfy the prescribed concentration or value for a parameter in Table B; and
(b) the Drinking Water Quality Regulator for Scotland considers that the failure in respect of that parameter is not trivial and is likely to recur,
the Regulator may, by notice given to Scottish Water, require it to apply for a departure in accordance with regulation 24(1).
2 Where the Drinking Water Quality Regulator for Scotland considers that a failure to which a report under regulation 19(1) relates is not trivial, it may by notice given to Scottish Water require Scottish Water to take such action as the Regulator may specify in the notice to—
(a) restore, as soon as possible, the quality of the water in question so that it satisfies the requirements of regulation 4(2);
(b) protect human health until the quality of the water is restored; and
(c) minimise the risk of the water failing to satisfy any such requirement.
3 Scottish Water must comply with a notice given to it under paragraph (1) or (2).
4 The exercise by the Drinking Water Quality Regulator for Scotland of the power conferred by paragraph (2) does not preclude the exercise by the Regulator, in relation to the same circumstances, of powers conferred by Part 2 of the Water Industry (Scotland) Act 2002.
2002 asp 3.

23 Power to direct local authorities in relation to domestic distribution systems
1 Where Scottish Water—
(a) investigates a failure or apprehended failure for the purposes of regulation 17(1); and
(b) that investigation establishes that the failure is due to a domestic distribution system in premises where water is supplied to the public (or to the maintenance of that system),
the Scottish Ministers may give directions to a local authority for the area in which the premises is located in relation to the exercise of its functions under sections 76FB and 76FC of the 1980 Act.
2 A direction under paragraph (1) may, in particular, specify—
(a) any advice which the local authority must require to be given to consumers in relation to the failure by notice under section 76FB(3)(d) of that Act;
(b) any steps which the local authority must require to be taken under section 76FB(3)(b) and (e) of that Act; and
(c) the period which the local authority must specify under section 76FB(3)(c) of that Act.
3 A local authority must comply with a direction given under paragraph (1) above.

1 Subject to paragraph (3), before providing a supply of water for human consumption purposes, Scottish Water must ensure that the water is—
(a) subjected to sufficient preliminary treatment;
(b) disinfected; and
(c) subjected to an adequate treatment process.
2 Scottish Water must—
(a) design, operate and maintain the disinfection and treatment process so as to keep disinfection and treatment by-products as low as possible without compromising the effectiveness of the disinfection or treatment; and
(b) verify the effectiveness of the disinfection and treatment process.
3 Where the Scottish Ministers confirm, by notice given to Scottish Water, that they are, in respect of a supply of water specified in the notice (“the specified supply”), satisfied that—
(a) Scottish Water was, or is (for such period as may be specified), unable to comply (in part or otherwise) with paragraph (1) without causing an interruption of the specified supply;
(b) bearing in mind the risks to human health which would be caused by any such interruption, to protect human health, the specified supply should not be interrupted; and
(c) other action (which would not interrupt the specified supply) will be, or has been, taken by Scottish Water to protect human health until it is able to comply with paragraph (1),
Scottish Water may provide the specified supply without complying with paragraph (1).
4 Where, by virtue of paragraph (3), Scottish Water provides a supply of water for human consumption purposes which does not comply with paragraph (1) it must, notwithstanding paragraph (3), comply with the other requirements of these Regulations (including taking such action as is necessary to ensure that the supply satisfies the requirements of regulation 4(2)).
5 Scottish Water must, before (or, in so far as it is not reasonably practicable to do so, promptly after) providing a supply of water for human consumption purposes which does not comply with paragraph (1), inform (in so far as it has not already done so) those of its consumers to whom it supplies the water—
(a) that the water has not been subjected to sufficient preliminary treatment, disinfected or, as the case may be, subjected to an adequate treatment process;
(b) of other action that has been taken, or will be taken, to ensure that the supply satisfies the requirements of regulation 4(2); and
(c) of the action (if any) that Scottish Water considers is necessary or desirable for the consumer to take to protect human health.
6 Paragraph (1) does not require Scottish Water to disinfect such groundwater as the Scottish Ministers may, by notice given to Scottish Water, specify.
7 For the purposes of this regulation—
(a) “adequate treatment process” means a continuously operated process of blending or purification treatment which removes, reduces or renders harmless any micro-organism, substance or parasite in, or property of, water, so that the water does not constitute a potential danger to human health;
(b) “sufficient preliminary treatment” means the treatment necessary (if any) to—
(i) remove or reduce the value or concentration of any property or substance which would interfere with disinfection; and
(ii) reduce turbidity to less than one Nephelometric Turbidity Unit; and
(c) water is supplied for human consumption purposes when it leaves a treatment works.

30 Risk assessment of each treatment works and its connected supply system
1 This regulation applies to each treatment works and its connected supply system from which water is supplied, or is to be supplied, by Scottish Water for human consumption purposes.
2 Scottish Water must assess each treatment works and its connected supply system (“the combined system”) so as to establish whether or not there is a significant risk of supplying unwholesome water from the combined system (or any part of it).
3 Each risk assessment must be recorded in writing (or in electronic form) and include—
(a) a description of the methods used to prepare it;
(b) where the assessment establishes that there is no significant risk of supplying unwholesome water from the combined system (or any part of it), a statement confirming this; and
(c) where it establishes that measures have been taken to remove a significant risk of supplying unwholesome water from the combined system (or any part of it)—
(i) monitoring data which verifies this; and
(ii) details of those measures.
4 Subject to paragraph (5), each risk assessment must be completed (and recorded) before 1st October 2015.
5 If the combined system (or part of it) is not in use on 1st January 2015, the risk assessment must be completed (and recorded) before the combined system or, as the case may be, that part of it) is used by Scottish Water to supply water for human consumption purposes.
6 Scottish Water must keep each risk assessment under review.
7 The Drinking Water Quality Regulator for Scotland may, by notice given to Scottish Water, require it to complete (and record) a risk assessment or, as the case may be, a review by a date specified in the notice.
8 Where Scottish Water becomes aware of any factors which make it likely that a risk assessment or a review will establish that there is a significant risk of supplying unwholesome water, it must inform the Drinking Water Quality Regulator for Scotland specifying the relevant factors and the measures it is taking or intends to take to mitigate the risk.

31 Procedure following risk assessment and prohibition of supply
1 As soon as reasonably practicable after Scottish Water has carried out a risk assessment, or a review of a risk assessment, under regulation 30, it must submit to the Scottish Ministers a copy of the risk assessment or, as the case may be, the review.
2 Where the assessment or review establishes that there is a significant risk of supplying unwholesome water, Scottish Water must, as soon as reasonably practicable, prepare and submit to the Scottish Ministers a report that—
(a) contains a full explanation including details of every property, organism or substance that has been identified as contributing to the risk; and
(b) specifies the measures to mitigate the risk that Scottish Water—
(i) has made operational as at the date of the report; and
(ii) intends to make operational.
3 Where the Scottish Ministers have received a report which states that there is or has been a significant risk of supplying unwholesome water, they may, by notice given to Scottish Water, require it—
(a) to maintain such specified measures for such period of time as they consider appropriate to mitigate the risk;
(b) to review, revise or make operational such specified measures by such date as they consider appropriate to mitigate the risk;
(c) to audit whether the measures have been effective by such means as may be specified;
(d) not to supply water for human consumption purposes from specified treatment works or supply systems, or not to so supply water unless specified conditions are satisfied; and
(e) to give the Scottish Ministers such information as they may require to monitor progress towards mitigation of that risk.
4 In paragraph (3), “specified” means specified in the notice given under that paragraph.
5 The Scottish Ministers may, by notice given to Scottish Water, revoke or amend a notice given under paragraph (3).

32 Copper and lead contamination from pipes
1 Where there is a risk (“the prescribed risk”) that water supplied by Scottish Water would, for the reason mentioned in paragraph (2), after leaving its pipes—
(a) contain a concentration of copper in excess of 2 mg/litre; or
(b) contain a concentration of lead in excess of 10 μg/litre,
Scottish Water must, subject to paragraph (3), treat the water in such a way as it considers will eliminate the prescribed risk or reduce it to a minimum.
2 The reason referred to in paragraph (1) is the presence in the water of a concentration of copper or lead which is attributable to the fact that copper or lead is the major component of such a pipe as is mentioned in section 76A(3)(a) of the 1980 Act, or its associated fittings.
3 Paragraph (1) does not require Scottish Water to treat water—
(a) if the treatment is unlikely to achieve a significant reduction in the concentration of copper or lead;
(b) supplied by it to any part of a water supply zone which the Drinking Water Quality Regulator for Scotland for the time being confirms, by notice given to Scottish Water, is in the Regulator’s opinion an insignificant part of that zone; or
(c) if treatment is not reasonably practicable.
4 Where Scottish Water—
(a) has reason to believe that water supplied by it for human consumption purposes from a pipe to which paragraph (5) applies contains, at the consumer’s tap, a concentration of lead which exceeds 10 µg/l; and
(b) has received from the owner of premises to which water is so supplied notice in writing (or in electronic form)—
(i) of the owner’s intention to replace so much of the pipe as belongs to him; and
(ii) of his desire that Scottish Water replaces the remainder of the pipe,
Scottish Water must modify or replace its part of the pipe.
5 This paragraph applies to a pipe—
(a) of which the major component is lead;
(b) which is subject to water pressure from a water main or would be so subject but for the closing of some valve; and
(c) which belongs in part to Scottish Water and, as to the remainder, to the owner of the premises to which the pipe supplies water for human consumption purposes.

PART 9 CONTROLS ON SUBSTANCES, PRODUCTS AND PROCESSES

33 Application and introduction of substances and products
1 Subject to paragraph (2), Scottish Water must not apply any substance or product to, or introduce any substance or product into, water which is to be supplied by it for human consumption purposes unless one of the requirements of paragraph (3) is satisfied.

See, in particular, Articles 5 to 7 (as read with Article 66).
may be applied or introduced, notwithstanding that none of the requirements of paragraph (3) is satisfied; but only if its application or introduction complies with—
(i) such conditions of use restricting the dosing concentration as for the time being apply in relation to that substance or product pursuant to a direction of the Scottish Ministers given to Scottish Water (in exercise of powers under section 56(3) of the Water Industry (Scotland) Act 2002); and
2002 asp 3.
(ii) such ‘other requirements’ (within the meaning of Directive 98/34/EC of the European Parliament and of the Council laying down a procedure for the provision of information in the field of technical standards and regulations and of rules on Information Society services as amended from time to time), in relation to such substances and products as have been communicated to the Commission in the form of a draft technical regulation in accordance with Article 8 of that Directive and whose adoption by a member State has also been communicated to the Commission.
OJ L 204, 21.7.1998, p.37, as amended by Directive 98/48/EC (OJ L 217, 5.8.1998, p.18), Council Directive 2006/96/EC (OJ L 363, 20.12.2006, p.81) and Regulation (EU) No 1025/2012 (OJ L 316, 14.11.2012, p.12).

EXPLANATORY NOTE
(This note is not part of the Regulations)
These Regulations aim to protect human health from the adverse effects of any contamination of water supplied by Scottish Water for human consumption purposes by ensuring that it is wholesome. In so far as they apply to water supplied by Scottish Water for human consumption purposes, they also apply the measures necessary to deliver the requirements of Council Directive 98/83/EC on the quality of water intended for human consumption (“the Directive”). Regulation 16 also supplements measures which deliver the requirements of Article 7(1) and (2) of Directive 2000/60/EC of the European Parliament and of the Council establishing a framework for Community action in the field of water policy (“the Water Framework Directive”).
Except for regulations 16, 17 to 22 (in part), 23 , 29(3) to (5), 30, 31, 33(12), 35(1)(a) and (b) and (2) (read with 35(4)), 36, 40 to 45, 46(2) and 48 to 52, the provisions of these Regulations revoke and re-enact (with some modifications) provisions of the Water Supply (Water Quality) (Scotland) Regulations 2001 (“the 2001 Regulations”). Except where the contrary intention appears, in so far as a thing done (such as a sample taken or a failure investigated) or having effect as if so done under a provision of the 2001 Regulations could have been done under the re-enacted provision (modified or not), that thing has effect as if done under that re-enacted provision.
Part 1 makes provision for citation, commencement, extent, application and interpretation.
Part 2 requires Scottish Water to designate areas of its supply as ‘water supply zones’.
Part 3 sets the standards of wholesomeness required for water supplied by Scottish Water.
Part 4 requires Scottish Water to take samples of water to check compliance with the standards of wholesomeness required. Samples taken from consumers’ taps must be selected at random.
Part 5 requires Scottish Water to identify its drinking water abstraction points and to take samples in order to check compliance with treatment standards and for risk assessment purposes.
Part 6 requires Scottish Water to immediately investigate any failure, or apprehended failure, to satisfy the standards of wholesomeness required. Scottish Water must immediately notify its consumers and other persons of any potential danger to human health. Scottish Water must report its findings. Where the failure affects water supplies to the public and the cause is due to a domestic distribution system in premises where water is supplied to the public, the Scottish Ministers may direct the relevant local authority in relation to the exercise of its powers to take remedial action under the Water (Scotland) Act 1980. In other cases, Scottish Water must take remedial action to restore a wholesome supply and to protect human health.
Part 7 provides for the authorisation of temporary departures from the wholesomeness standards.
Part 8 requires Scottish Water to treat and disinfect its water supplies to render harmless any contaminants. It also requires Scottish Water to assess each of its treatment works and connected supply systems to establish if there is any significant risk of it supplying unwholesome water. The Scottish Ministers may require Scottish Water to take steps to mitigate any such risk. Scottish Water must also treat its water to minimise any risk of copper and lead standards being exceeded.
Part 9 provides controls in relation to the application and introduction of substances, products and processes in relation to water supplied by Scottish Water for human consumption purposes.
Part 10 makes it an offence to contravene some of the provisions in Parts 8 and 9.
Part 11 makes provision in relation to records, health risk events and disclosure of information.
Part 12 makes provision in relation to incidental powers of entry for Scottish Water, and makes connected provision for an offence of obstruction and compensation for damage.
Part 13 makes provision in relation to the enforcement powers of the Scottish Ministers. In particular, regulation 46(2) ensures that a duty or requirement which is not imposed (in whole or part) in exercise of powers under section 76B of the Water (Scotland) Act 1980 may be enforced by means of a default order under section 11(2) of that Act in the same way as a duty or requirement imposed in exercise of powers under section 76B of that Act.
Part 14 confers an incidental functions on local authorities. Part 15 makes consequential amendments and revocations. Part 16 makes transitional provisions.
The powers in section 2(2) of the European Communities Act 1972 (c. 68) (“the 1972 Act”) are exercised so far as may be necessary (to supplement the other powers cited) for the purposes of implementing, or enabling the implementation of, obligations arising under or by virtue of the Directive or Article 7(1) and (2) of the Water Framework Directive, and for the purposes of dealing with matters arising out of or related to any such obligations.

regulations 48 and 49 for the purposes of making amendments to the Water (Scotland) Act 1980 and the Building (Scotland) Act 2003 in consequence of regulations 17 to 23 (in so far as those regulations are made pursuant to Articles 4 and 8 of the Directive), and
regulation 50 for the purposes of revoking the Surface Waters (Abstraction for Drinking Water) (Classification) (Scotland) Regulations 1996 in consequence of the repeal (by Article 22(1) of the Directive 2000/60/EC establishing a framework for Community Action in the field of water policy) of Council Directive 75/440/EEC (OJ L 194, 25.7.1975, p. 26) and Council Directive 79/869/EEC (OJ L 271, 29.10.1979, p. 44).
