Stormwater + Wastewater Pretreatment

The City of Hayward is responsible for the implementation of stormwater and wastewater pretreatment programs that prevent harmful pollutants from entering local creeks, the Bay, and the Hayward Wastewater Treatment Facility. Stormwater and wastewater systems are two separate systems with different functions.

STORMWATER

The stormwater system refers to infrastructure designed to collect and convey surface water in order to prevent flooding. The stormwater system consists of a network of inlets (storm drains), gutters, and pipelines that convey surface water to local water bodies, such as creeks, rivers, and the Bay. Surface water that enters the stormwater system is not treated prior to entering local water bodies, therefore it is important to prevent pollutants from entering the stormwater system.

Permits and Regulation 

The Federal Clean Water Act and the California Porter-Cologne Water Quality Act require cities discharging to the San Francisco Bay to obtain a National Pollution Discharge Elimination System (NPDES) Municipal Regional Permit (MRP). The MRP governs a variety of activities including industrial and commercial businesses, illegal stormwater discharges, and new development and redevelopment.  

 

WASTEWATER PRETREATMENT

The sanitary sewer system refers to infrastructure that transports wastewater to the Hayward Water Pollution Control Facility (WPCF). Wastewater that enters the sanitary sewer system must be treated before being discharged into the Bay. The sanitary sewer system consists of piping and pump stations that convey wastewater from households and businesses to the WPCF where it is filtered, treated, and discharged.   

Permits and Regulation 

The National Pretreatment program is a component of the National Pollution Discharge Elimination System (NPDES). The program is a cooperative effort of federal, state, and local regulatory agencies to protect water quality. The EPA and authorized NPDES state pretreatment programs approve local municipalities to perform permitting, administrative, and enforcement tasks for discharges into the municipalities’ publicly owned treatment works (POTWs), such as the WPCF. The City of Hayward is responsible for administering pretreatment programs and regulating businesses including food service establishments, mobile businesses, dental offices, and commercial and industrial facilities.
