For the purpose of determining payments to be made under this section, after the commencement of the South-Western Suburbs Drainage Act Amendment Act 1970, the prescribed amount shall be deemed to be $4 332 898 and the liability of the councils shall, for the purposes of calculating interest in respect of payments made pursuant to this section after the commencement of the South-Western Suburbs Drainage Act Amendment Act 1970, be deemed to have arisen on the first day of May of the financial year immediately preceding the day of commencement of the South-Western Suburbs Drainage Act Amendment Act 1970.
	(2)	For the purposes of ascertaining the amount payable pursuant to this section by each council on the first day of May next following the day of commencement of the South-Western Suburbs Drainage Act Amendment Act 1970 and each first day of May that occurs thereafter, the Treasurer shall, having regard to the amendments effected to this Act by that Act, recalculate the payments required to be made by each council and the payments, as recalculated, shall be the payments required to be made pursuant to this section.
	(3)	Upon the application of a council the Treasurer may defer payment, upon such terms and conditions as he specifies, of such part of any payment required to be made by that council pursuant to this section on the first day of May, next following the day of commencement of the South-Western Suburbs Drainage Act Amendment Bill 1970, as is equal to the difference between the amount of the payment that the council would have been required to make pursuant to this section together with the amount of the payment, if any, that the council would have been required to make pursuant to section 8 of the South-Western Suburbs (Supplementary) Drainage Act 1966, had the South-Western Suburbs Drainage Act Amendment Act 1970 not been enacted and the amount of the payment that the council is required to make pursuant to this section.

The Treasurer shall, in every tenth year after the year in which payments commence under section 10, vary or re-affirm as he deems proper, having regard to the rates paid by him on loan moneys raised at long-term rates during the preceding year, the rate of interest to be payable by the councils on amounts from time to time remaining unpaid. Upon any such variation the remaining annual instalments payable by each council shall be varied so as to complete repayment at the end of the fifty-third year after the notification referred to in section 8.
12—Councils responsible for maintenance of drains
	(1)	Upon completion of a major drain or part of a major drain within the area of any one of the councils the Minister shall notify that council of such completion.
