Pub. L. 83-364, tit. I, sec. 101

Sec. 101. The Commissioners are authorized, in their discretion, to fix from time to time, the rates charged by the District for water and water services furnished by the District water supply system. Such rates so fixed, whether involving one or more changes in rate, or one or more changes in the basic quantity of water to be supplied at a given rate, or the combined effect of both such changes, shall not, in any event, result in increasing by more than 33 1/3 per centum the rates in effect on the day preceding the effective date of this section. In computing the charge for the consumption of water in excess of the minimum amount allowed for metered service, if such charge is for a period beginning prior to so fixing such rates and ending thereafter, the charge for such excess consumption shall be prorated on a monthly basis, in accordance with the rates prevailing in the respective periods. Nothing in this title shall be construed to modify the provisions of the Act approved April 14, 1932 (47 Stat. 79, ch. 100; sec. 43–1530. D. C. Code) relating to the delivery of water from the District water supply system to the Washington Suburban Sanitary Commission.
