Recalculation factor: interpretation

5.—(1) In article 6, in relation to each class of hereditaments—

(a) in any formula—

• y is the relevant amount of water in relation to the period of 3 years ending immediately before the relevant preceding year;

• Y, subject to article 6(3), is the relevant amount of water in relation to the period of 3 years ending on 31st March 1999;

• Z is a number having the same value as y in the last foregoing year in relation to which the applicable recalculation factor for that class was determined in accordance with article 6(2); and

• T has the same meaning as in the definition of “the standard formula” in article 2; and

(b) “relevant amount of water” in relation to a relevant designated person and any period of 3 years means the annual average, over 3 years, expressed in megalitres to the nearest tenth part, calculated in accordance with the formula set out in paragraphs (2) and (3).

(2) The formula referred to in paragraph (1)(b) is

A - B

where—

• A is the estimated annual average amount of water put into supply by that person in the period of 3 years, being water supplied—

  (a)

  to any other person in bulk, that is to say for the purposes of augmenting or constituting the supply to be given by that person; or

  (b)

  otherwise,

  • less half the estimated annual average amount of non-potable water so supplied otherwise than in bulk; and

• B is half the annual average amount of water estimated to have been taken or supplied in bulk during that period of 3 years.

(3) Where the relevant designated person did not supply water throughout any year in a period of 3 years, paragraphs (1) and (2) shall apply as if for the reference to the annual average over 3 years there were substituted a reference to the annual average over the number of years throughout which water was supplied; and for the purposes of this paragraph any temporary suspension of supply shall be disregarded.
