Pub. L. 83-364, tit. II, sec. 207

Sec. 207. The sanitary sewer service charges established under the authority of this title shall be based on the water consumption of, and water service to, the properties served, and be determined by one of the following methods: (a) Where water is supplied from the District water supply system at meter rates, the Commissioners shall establish the sanitary sewer service charge as a percentage of the water charge applicable in the District, but such percentage shall not exceed 60 per centum of the water charge. (b) Where water is supplied from the District water supply system, which water is not measured by meter, but is supplied at special business and miscellaneous rates, the Commissioners shall establish the sanitary sewer service charge at a percentage of such special business and miscellaneous rates, but such percentage shall not exceed 60 per centum of such rates. (c) For each property using water, all or part of which is from a source or sources other than the District water supply system, the Commissioners shall establish a sanitary sewer service charge separate from and in addition to any sanitary sewer service charge levied under paragraph (a) or (b) of this section. Such separate or additional sanitary sewer service charge shall be measured by the quantity of water from the source or sources other than the District water supply system discharged into the District sanitary sewer system from said property. The owner or occupant of each such property shall install and maintain, without cost to the District, a meter or meters to measure the quantity of water received from other than the water supply system of the District, and the sanitary sewer service charge based upon water received from other than the water supply system of the District shall be the same in amount as would be paid by the owner of a metered property receiving the same quantity or water from the water supply system of the District. No meter shall be installed or be used for such purpose without the approval of the Commissioners. In the event the owner or occupant of property fails or refuses to furnish and properly maintain such meter or meters as are prescribed herein in the manner required by the Commissioners, then the supply of water from the District water supply system to the property or premises may be suspended by the Commissioners and the said supply shall not be restored until the metering of such supplementary water source has been accomplished by the owner or occupant to the satisfaction of the Commissioners, and any costs devolving upon the District as a result of the suspension of service from the District water supply system shall be paid to the District prior to the restoration of water service from the District water supply system. (d) Wherever a property upon which a sanitary sewer service charge is imposed uses water from the water supply system of the District for an industrial or commercial purpose in such manner that the water so used is not discharged into the sanitary sewage works of the District, the quantity of water so used and not discharged into the sanitary sewage works of the District may be excluded in determining the sanitary sewer service charge on such property, if such exclusion is previously requested in writing by the owner or occupant thereof. Upon such request, the quantity of water so used and not discharged into the sanitary sewage works of the District shall be measured by a device or devices approved by the Commissioners, installed and maintained without cost to the District, and the sanitary 68 Stat. 107 sewer service charge to be imposed on such property shall be not more than 60 per centum of the water charge which would have been charged such property if the amount of water so used and not discharged into the sanitary sewage works of the District had not been included in the amount of water used by such property: Provided, That all water from the water supply system of the District used by such property shall be paid for at established rates, whether or not such water is discharged into the sanitary sewage works of the District. Where, in the opinion of the Commissioners, it is not practicable to install a measuring device to determine continuously the quantity of water used for such industrial or commercial purposes and not discharged into the sanitary sewage works of the Distinct, the Commissioners shall determine periodically, in such manner and by such methods as the Commissioners may prescribe, the quantity of water from the water supply system of the District discharged into the sanitary sewage works of the District, and the sanitary sewer service charge shall be based on such estimated quantity of water at the percentage authorized by this paragraph. Any dispute as to such estimated amount shall be decided by the Commissioners and such decision shall be final; and in the event the owner or occupant fails to furnish and maintain such measuring devices or to facilitate the periodic determinations by the Commissioners as prescribed herein, then the privilege of excluding some portion of the water used from the District water supply system from the charges for sanitary sewer service shall be forfeited and the charges for sanitary sewer service shall be based on the full amount of the water used from the District water supply system.
