Clean Water

The City of Dublin's Clean Water Program is a federally-mandated program under the Clean Water Act. The purpose of the Clean Water Program is to eliminate pollutants, such as oil, dirt, pesticides, litter, and other similar contaminants, from entering the storm drain system so only clean water enters our waterways and ultimately the San Francisco Bay.

A final Municipal Regional Stormwater NPDES Permit (MRP) was adopted by the Water Board at a hearing on October 14, 2009. The MRP covers stormwater discharges from municipalities and local agencies in Alameda, Contra Costa, San Mateo, and Santa Clara counties, and the cities of Fairfield, Suisun City, and Vallejo.

Urban Runoff
Stormwater runoff of occurs naturally as part of the hydrologic cycle. Humans can affect the quality of the water that enters or creeks streams, and even the San Francisco Bay. As land use changes from open space to either agricultural or to urbanization, the characteristics of the water flow changes. Urban runoff is the water that flows from these areas after land use has changed. Urban runoff can be either wet or dry weather flows.

Increasing Public Awareness
With stormwater pollution being the leading cause of water quality problems in creeks and the San Francisco Bay, the City of Dublin continues in its efforts to increase public awareness.

Informational pamphlets are available year-round at the Public Works front counter at the Dublin Civic Center, as well as on this website. In addition, a clean water booth is displayed at the City's major community events, including the St. Patrick's Day Festival, where the City's clean water program coordinator is available to answer any questions and provide the public with informational pamphlets about how to reduce pollutants entering our waterways.

The City also has many natural filters that have been installed on City property and on private property at many Dublin businesses. These natural filters or "bioswales" (shown below) serve as a natural way to absorb much of the runoff pollutants within grasses, rocks and other landscaping materials design to catch pollutants.
