13.12.470 – Additional pretreatment measures

  1. Whenever deemed necessary, the Director of Public Works may require Users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage waste streams from industrial waste streams, and such other conditions as may be necessary to protect the POTW and determine the User's compliance with the requirements of this chapter.
  2. The Director of Public Works may require any User discharging into the POTW to install and maintain, on the User's property and at the User's expense, a suitable storage and flow-control facility to ensure equalization of flow.  A wastewater discharge permit may be issued solely for flow equalization.
  3. Grease, oil, and sand interceptors shall be provided when, in the opinion of the Director of Public Works, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil, or sand; except that such interceptors shall not be required for residential Users.  All interception units shall be of type and capacity approved by the Director of Public Works 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 User at the User's expense.
  4. Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
