D.C. Mun. Regs. tit. 21, r. 21-207
The provisions of this section shall apply to all improved real property and all construction sites within the District of Columbia.
The General Manager shall identify those properties that discharge groundwater into the District's sewer system and those locations where it is practicable to install a groundwater meter.
It shall be deemed practicable to install a groundwater meter on any property where a closed conveyance having a diameter of one (1) inch or greater is necessary to accommodate the discharge of groundwater into the sewer system.
The General Manager shall give the owners or occupants of the properties identified in accordance with § 207.2 written notification that they will be required to do the following:
The owners of the real property shall install the meters determined by the General Manager to be necessary to measure the discharge of groundwater within sixty (60) days of written notification by WASA.
WASA shall conduct an on-site inspection at the end of the sixty (60) day period to verify that the meters determined by the General Manager to be necessary have been properly installed.
After WASA has confirmed proper installation of the required meters, WASA shall establish an account, separate from the water and sewer service charge account, for the purpose of billing the owner or occupant for groundwater discharged into the District's sewer system.
The meter or meters measuring groundwater discharged into the District's sewer system shall be read periodically and a bill for those charges shall be rendered.
WASA shall provide the owner or occupant with written notice of a change in the billing cycle at least thirty (30) days before the beginning of the new cycle.
If at any time a meter fails to register correctly or bears evidence of tampering, as determined by WASA, the sanitary sewer service charge shall be based on the average previous measured discharge of groundwater for three (3) previous billing cycles.
Upon an owner or occupant's failure to pay the groundwater sanitary sewer service charges or to install and maintain the required meters within the allotted time, WASA may do the following:
WASA may inspect the improved property or the construction site to ensure that the meters determined by the General Manager to be necessary are properly installed and maintained.
Prior to removing the required meters from the improved property or construction site, the owner shall advise WASA and request a final reading.
WASA shall read the meters servicing the improved property or construction site and provide the owner with a final statement of account.
If the meter or meters are removed before WASA obtains a final reading, the ground water sewer service charge shall be based on the average previous consumption for the period of the installation.
