Industrial Pretreatment Program (IPP)

The Industrial Pretreatment Program (IPP) is the City’s premier organization that oversees water quality issues, and some of its goals are:
  1. To educate the community about causes and effect of residential, commercial and industrial activities with water quality.
  2. To stress to residents and businesses the differences between the sanitary and storm sewers.
  3. To encourage the employment of less polluting and more environmentally friendly practices through outreach and when necessary regulatory actions.

This is accomplished with a staff of 4 Source Control Inspectors responsible for various aspects of the City’s activities that overlap with wastewater pollution prevention and storm water issues.

There are two pipeline collection systems in most cities. One is the stormwater collection system in which rainwater is directed to the bay untreated. The only non-storm water allowed to enter this system is incidental landscape irrigation runoff, condensation water from HVAC systems (heating, ventilation, and air-conditioning), and water used to test fire suppression equipment. All other discharges are considered non-stormwater. If you notice sewage, automotive fluids, trash, paint & pesticides or other substances spilling into a storm drain please immediately call: (510) 412-2001/620-6542 or 1-800-NO DUMPING.

The other pipeline collection system is the sanitary sewer, which is the piping from sinks, toilets, floor drains, and industrial/commercial business operations. This collection system is part of the wastewater treatment plant where the collected wastewater is treated by mechanical and biological operations and discharged to the bay according to the terms of a state/federal permit.
