Water Pollution Prevention for Businesses

A Healthy Bay is Good Business!

Business owners and managers can help prevent water pollution in the San Francisco Bay in many ways. Understanding how water pollution can occur and adopting behaviors designed to prevent pollution can significantly reduce harmful discharges. Preventing pollution is the best and most economical way to restore the health of local waterways and preserve these valuable natural resources for ourselves and future generations.

It is important to remember that almost everywhere in the Bay Area, the storm drainage system carries rainwater and other runoff from roads, parking lots, and roof drains directly to local creeks and the Bay, with no treatment. The “sanitary” sewer carries wastewater from sinks, toilets, and other indoor drains to local wastewater treatment plants, where treatment processes remove biological waste products before the treated water flows on to the Bay.

Neither of these systems -- storm drain or sanitary sewer -- is designed to handle solvents, metals, or chemicals.

Our Pretreatment Program, comprised of Industrial Waste Inspectors, Laboratory Chemists and Field Technicians are responsible for protecting the sanitary sewer collection system and treatment plant through the enforcement of regulations regarding the disposal of commercial and industrial wastewater and stormwater discharge.

A selection of brochures on industrial wastewater pretreatment, Best Management Practices for stormwater, and water pollution prevention is available. For more information, view the Pretreatment Program and Storm Drain pages, or contact Pretreatment staff through e-mail or by calling 408-730-7260, TDD 408-730-7501.
