A commercial or industrial property may be eligible for a sewer allowance when the amount of water discharged into the District's sewer is less than the amount of water it receives from the District's water distribution system.
The following two (2) methods shall be used to determine the extent and amount of the sewer allowance:
The flat allowance shall be subtracted from the sewer service charge only during the period May 15th to October 15th of each year.
To extend the period for the flat allowance, property owners shall submit a written request and justification. The request must be approved by the Chief before it can go into effect.
Upon receipt of a written request for a sewer allowance, the Chief shall conduct an audit of the property to determine whether and the conditions under which, the property is eligible for a sewer allowance.
Owners of commercial and industrial properties shall be notified in writing whether the properties are eligible for a sewer allowance and the amount of any sewer allowance.
Commercial and industrial property owners shall allow the Bureau access to audit water use and to verify that the amount is not being discharged into the District's sewer system.
During any period when the owner or occupant of eligible property fails to permit an audit under this section, all privileges associated with the sewer allowance shall be forfeited and the charges for sewer service shall be based on the full amount of water received by the property from the District water supply system.
