(a) The sanitary sewer service charges established under the authority of this subchapter shall be based on the following:

(1) A billing methodology that takes into account both the water consumption of, and water service to, a property where water is supplied from the District water supply system.

(2) Repealed.

(3)(A) For any unimproved real property under construction that discharges groundwater into a District-owned sanitary sewer, or combined sewer, or for any real property using water, part of which is from a source or sources other than the District water supply system, the real property owner shall pay a sanitary sewer service charge separate from and in addition to any sanitary sewer service charge levied in paragraphs (1) or (2) of this subsection. For any improved real property that discharges groundwater into a District-owned sanitary or combined sewer, the real property owner shall not be subject to payment of a separate and additional charge for discharges of groundwater, but shall pay for discharges of cooling water into a District-owned sanitary of combined sewer that are derived from a source or sources other than the District water supply system.

(B)(i) For unimproved real property under construction the separate and additional sanitary sewer service charge shall apply to and be measured by the quantity of water that is derived from the groundwater and is discharged into the District sanitary or combined sewer system.

(ii) For improved real property, the separate and additional sanitary sewer service charge shall apply to and be measured by the quantity of water that is derived from the cooling water and is discharged into the District sanitary or combined sewer system.

(iii) For real property using water from a source or sources other than the District water supply system, such separate and additional 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 or combined sewer system from the property.

(C) Unless the Mayor determines that it is not practicable, the owner of the real property shall install and maintain, at a location approved by the Mayor and without cost to the District, any sanitary meter or device necessary to measure the quantity of groundwater, cooling water, or water from other than the District water supply system that is discharged into the District’s sanitary sewers.

(D) For purposes of this section, the determination made by the Mayor pursuant to Chapter 8 of Title 47 as to whether property is improved or unimproved shall apply.

(4) 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 Mayor, installed and maintained without cost to the District, and the sanitary sewer service charge to be imposed on such property shall be the amount 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 Mayor, 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 District, the Mayor shall determine periodically, in such manner and by such methods as the Mayor 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 Mayor 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 Mayor 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.

(b) Notwithstanding the provisions of subsection (a), the Council of the District of Columbia is authorized, in its discretion, from time to time to establish 1 or more sanitary sewer service charges at such amount as the Council, on the basis of a recommendation made by the Mayor, finds it necessary to meet the expense to the District of furnishing sanitary sewer services, including debt retirement.

(c) Repealed.

§ 34–2112. Sanitary sewer service charges for United States government.

(a) The sanitary sewer service charges prescribed herein shall be applicable to all sanitary sewer services furnished by the sanitary sewage works of the District through any connection thereto for direct use by the government of the United States or any department, independent establishment, or agency thereof, and such charges shall be predicated on the value of water and water services received by such facilities of the government of the United States or any department, independent establishment, or agency thereof from the District water supply system. Payment of the said sanitary sewer service charge shall be made as provided in subsection (b) of this section.

(b)(1) Beginning in the second quarter of fiscal year 1990, the government of the District of Columbia shall receive payment for sanitary sewer services from funds appropriated or otherwise available to the Federal departments, independent establishments, or agencies.
