4—Amendment of section 65CAA—Related principles
Section 65CAA(1)—after paragraph (e) insert:
	(f)	to the extent—
	(a)	that meters are read on a periodic basis so as to recover any water use charge over a series of periods during a financial year (with each such period being referred to as a billing period for the purposes of this paragraph); and
	(b)	that the charges so imposed increase according to the amount of water supplied over a billing period (so as to form tiers of rates that vary according to the amount of water supplied),
if the amount of water supplied over a billing period is less than the amount up to which the first tier of rates is charged (the maximum amount for tier 1), the difference between the amount supplied during the billing period and the maximum amount for tier 1 must be carried over to the next billing period within the relevant financial year (if there is such a period remaining in that financial year) so that the maximum amount for tier 1 in that next billing period will be taken to be increased by the amount carried over (and if the amount of water supplied over that next billing period is less than the maximum amount for tier 1, as increased by the amount carried over from the preceding billing period, then there will be a further carry over of the difference to the next billing period again (if there is such a period remaining in the financial year) so as to result in another increase in the maximum amount of tier 1, and so on for each and every billing period for so long as such an excess remains with respect to that financial year).
