Whenever deemed necessary, the Public Works Director or other designee may require industrial users to restrict the industrial user's discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the municipal wastewater system and determine the industrial user's compliance with the requirements of this chapter.
A. Each person discharging, into the municipal wastewater system greater than 100,000 gallons per day or greater than 5% of the average daily flow in the system, whichever is lesser, may be required by the Public Works Director or other designee to install and maintain, on his or her property and at his or her expense, a suitable storable and flow control facility to ensure equalization of flow over a 24 hour period. The facility shall have a capacity for at least 50% of the daily discharge volume and shall be equipped with alarms and a rate of discharge controller. A wastewater permit may be issued solely for flow equalization.
B. Grease, oil and sand interceptors shall be provided, when, in the judgment of the Public Works Director or other designee, they are necessary for the proper handling of wastewater containing excessive amounts of grease, flammable substances, sand, suspended solids or other harmful substances; except that such interceptors shall not be required for residential users. All interception units shall be of type and capacity approved by the city and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the owner, at his or her expense.
C. Industrial users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
