PART 2 WATER SERVICES: REASONABLE COST

Dwellings
3. For the purposes of section 6 of the 1980 Act, in determining what is a reasonable cost to take pipes affording a supply of wholesome water, where this is required for domestic purposes, to such point or points as will enable a building (or a part of it), which consists only of one or more dwellings, to be connected to the pipes (at a reasonable cost), the cost of taking the pipes (affording the supply) to the point or points is a reasonable cost only if the cost to Scottish Water does not exceed the amount determined by the formula—
Amount = Cw × Nwr[1−(11+r)12]
where—
“Cw” is the figure which is the average of—
(a) the current charge (fixed as an annual charge) for or in connection with a supply of water to an unmetered dwelling in band B; and
(b) the current charge (fixed as an annual charge) for or in connection with a supply of water to an unmetered dwelling in band C; and
“Nw” is the number of dwellings in the building (or, as the case may be, the part of it) which is to be connected to the pipes at the point or points in question.

Non-dwellings
4. For the purposes of section 6 of the 1980 Act, in determining what is a reasonable cost to take pipes affording a supply of wholesome water, where this is required for domestic purposes, to such point or points as will enable a building (or a part of it), which does not contain any dwellings, to be connected to the pipes (at a reasonable cost), the cost of taking the pipes (affording the supply) to the point or points is a reasonable cost only if the cost to Scottish Water does not exceed the amount determined by the formula—
Amount = Ucw × Vdomr[1−(11+r)6]
where—
“Ucw” is the predicted average amount that water services providers are to be charged by Scottish Water per cubic metre of water supplied during the connection year, calculated using the formula in paragraph 1 of Schedule 1; and
“Vdom” is the relevant figure (expressed in cubic metres per annum) in the table in Schedule 2 which corresponds to the maximum number of persons to be employed at the building (or, as the case may be, the part of it) in question at any point in the connection year and to whether that building (or that part of it) has a toilet, shower or canteen (or a combination of these).

Calculating cost
5. (1) In regulations 3 and 4, “the cost to Scottish Water” is the total of—
(a) the costs which would be incurred by Scottish Water in taking pipes to the point or points referred to in regulation 3 or, as the case may be, regulation 4; and
(b) the costs which would be reasonably and necessarily incurred by Scottish Water to ensure that the pipes afford a supply of wholesome water sufficient for the domestic purposes of all owners and occupiers of the building (or the part of it) to be connected to the pipes.
(2) In calculating the cost to Scottish Water for the purposes of regulations 3 and 4 the amount of any charge payable under a charges scheme must be left out of account.
(3) In paragraph (1)(b), “owner” and “occupier” are to be construed in accordance with the meanings given to those terms in section 109(1) of the 1980 Act.

PART 3 SEWERAGE SERVICES: REASONABLE COST

Dwellings
6. For the purposes of section 1 of the 1968 Act, in determining what is a reasonable cost to take public sewers to such point or points as will enable the owner of premises (or a part of them), which consists only of one or more dwellings and which is to be served by the public sewers, to connect the owner’s drains or private sewers (at a reasonable cost), the cost of taking the public sewers to the point or points is a reasonable cost only if the cost to Scottish Water does not exceed the amount determined by the formula—
Amount = Cs × Nsr[1−(11+r)12]
where—
“Cs” is the figure which is the average of—
(a) the current charge (fixed as an annual charge) for or in connection with the provision of sewerage to, or the disposal of sewage from, an unmetered dwelling in band B; and
(b) the current charge (fixed as an annual change) for or in connection with the provision of sewerage to, or the disposal of sewage from, an unmetered dwelling in band C; and
“Ns” is the number of dwellings in the premises (or, as the case may be, the part of them) served by the drains or private sewers (of the owner) which are to be connected to the public sewers at the point or points in question.

Non-dwellings
7. (1) For the purposes of section 1 of the 1968 Act, in determining what is a reasonable cost to take public sewers to such point or points as will enable the owner of premises (or part of them), which does not contain any dwellings and which is to be served by the public sewers, to connect the owner’s drains or private sewers (at a reasonable cost), the cost of taking the public sewers to the point or points is a reasonable cost only if the cost to Scottish Water does not exceed the amount determined by the formula—
Amount = Ucs × Vdom× 0.95r[1−(11+r)6]
where—
“Ucs” is the predicted average amount that sewerage services providers are to be charged by Scottish Water per cubic metre of sewage disposed of during the connection year, calculated using the formula in paragraph 2 of Schedule 1; and
“Vdom” is the relevant figure (expressed in cubic metres per annum) in the table in Schedule 2 which corresponds to the maximum number of persons to be employed at the premises (or, as the case may be, the part of them) in question at any point in the connection year and to whether that premises (or that part of them) has a toilet, shower or canteen (or a combination of these).
(2) In paragraph (1), if the premises (or the part of them) in question has more than one building (or part of a building), “Vdom” is to be construed as the total of the corresponding relevant figures for each building (or, as the case may be, each part of a building) in the table in Schedule 2.

Calculating cost
8. (1) In regulations 6 and 7, “the cost to Scottish Water” is the total of—
(a) the costs which would be incurred by Scottish Water in taking public sewers to the point or points referred to in regulation 6 or, as the case may be, regulation 7; and
(b) the costs which would be reasonably and necessarily incurred by Scottish Water to ensure that domestic sewage, surface water and trade effluent from the premises (or the part of them) to be connected to the public sewers will be effectually drained and dealt with.
(2) In calculating the cost to Scottish Water for the purposes of regulations 6 and 7 the amount of any charge payable under a charges scheme must be left out of account.
(3) In paragraph (1)(b), “domestic sewage”, “surface water” and “trade effluent” are to be construed in accordance with the meaning of those expressions in section 59(1) of the 1968 Act.

EXPLANATORY NOTE
(This note is not part of the Regulations)
These Regulations make provision for determining the points to which Scottish Water must take water supply pipes and public sewers so as to enable connections to be made at a reasonable cost.
Part 2 makes provision for determining the reasonable cost of taking pipes affording a supply of water to such point or points as will enable a building (or a part of it) to be connected pursuant to section 6(2) of the Water (Scotland) Act 1980. If taking the pipes to that point or, as the case may be, those points exceeds a reasonable cost, then Scottish Water is not required to do anything pursuant to that section.
Part 3 makes provision for determining the reasonable cost of taking public sewers (“the sewers”) to such point or points as will enable the owner of premises (or a part of them) to connect the owner’s drains or private sewers pursuant to section 1(2)(a) of the Sewerage (Scotland) Act 1968. If taking the public sewers to that point or, as the case may be, those points exceeds a reasonable cost, then Scottish Water is not required to do anything pursuant to that section.
Part 4 revokes the Regulations that previously dealt with these matters.
No business and regulatory impact assessment has been prepared for these Regulations as no significant change is foreseen to the existing financial and administrative impacts upon business, charities or voluntary bodies.
