San Leandro operates a publicly owned treatment works (POTW) for wastewater treatment.
The POTW, part of the City's Water Pollution Control Division, includes an advanced biological wastewater treatment plant and over 120 miles of pipelines and pumping stations serving the northern two thirds of the city. The Environmental Services Section is responsible for protecting this system, as well as POTW workers and the environment, from discharges that may cause damage or create hazardous conditions.
The Pretreatment Program
Environmental Services manages an EPA-approved pretreatment program and implements federal, state, and local regulations. The program regulates the discharge of industrial waste to the sanitary sewer through inspections, monitoring, and permits. The City’s Uniform Wastewater Discharge Regulations, Chapter 3-14 regulates discharges to the wastewater system.
Non-household users of the sanitary sewer in the following "classes" must obtain a permit:
- Class A - Industrial users subject to Federal Pretreatment Standards.
- Class B - Users not covered by Federal Pretreatment Standards but have the potential to discharge toxic pollutants.
- Class C - Users discharging pollutants that are generally not toxic but could overload the POTW and cause it to violate operating limits.
- Class D - Users with "special" discharges from sources not associated with routine industrial or commercial fixed processes.
