(a) Metering devices. If a person who discharges industrial waste into the wastewater system installs and maintains in proper working condition a wastewater metering device of a type approved by the director, the actual wastewater flow from the premises will be the basis for computing charges for services.
(b) Measurements without a meter. On premises where water is obtained exclusively from the water system and no wastewater metering device is installed, the director shall compute the wastewater flow, for purposes of determining service charges, based on the water consumption during the previous month.
(c) Wastewater from private sources. On premises where all or part of the water is obtained from a source other than the water system and no wastewater metering device is installed, the owner shall provide and maintain a metering device, of a type approved by the director, to measure sources of private water.
(d) Estimated usage. If an activity on premises consumes water by evaporation, includes water in a product, or discharges water into a storm sewer, the owner may make application to the director for reduction in the volume of wastewater estimated to be discharged from the premises. The application must contain supporting data, including but not limited to a flow diagram showing the route and destination of the water supply and wastewater. (Ord. Nos. 19201; 26925; 28084)
