• Clean Water Program

  • The purpose of the Clean Water Program is to efficiently utilize available funding to reduce pollution of the stormwater as it enters into our creeks and the bay, and to maintain public storm drain facilities. The Program's activities are managed in accordance with National Pollution Discharge Elimination System (NPDES) Permit requirements enforced by the San Francisco Regional Water Quality Control Board and include performing field inspections (storm drain system, creeks, and illicit connections), conducting educational and outreach activities (informational presentations, attending public events, and coordination of storm drain stenciling), performing storm drain cleaning, regularly sweeping streets, and implementing new development/redevelopment stormwater controls.

    The following is a general list of program activities in Danville:

  •     Clean Water Program Overview

    The Town's Clean Water Program exists to comply with the Federal and State Clean Water regulations governing "non-point source" pollution. Such pollution is mobilized, transported and discharged with storm water runoff, which flows untreated into a storm drain and ultimately flow into the San Francisco Bay. We work with residents, businesses and visitors to make sure we keep our waterways healthy. Our efforts to prevent stormwater pollution is regulated under the jurisdiction of the San Francisco Bay Regional Water Quality Control Board (Region 2). The Town of Danville is a member of the Contra Costa Clean Water Program.


        Inspection Activities
    Danville Inspection activities include an annual Business Inspection Program and Code Enforcement Program to protect water quality
        Maintenance Activies
    Town Maintenance activities include: inspecting and cleaning Town drainage systems on an annual basis; installation and maintenance of trash removal devices in drain inlets in the downtown area; monthly sweeping of public residential streets and weekly sweeping of public commercial streets (Street Sweeping Schedule & Map); installation and maintenance of new trash and recycling containers downtown; and the application of Integrated Pest Management (IPM) practices for landscape, pond and building maintenance.
        New Development Regulations
    New development in Danville is also subject to Clean Water regulations. Both commercial and residential development meeting certain thresholds are required to capture and treat all runoff from the development so that only clean stormwater leaves the site. These integrated treatment facilities must be incorporated in each development at the initial planning and design stage. Then at the construction stage, detailed construction plans are plan checked and a long term maintenance and operation plan is developed to ensure that these facilities are maintained by the property owner in the long term.
        Pollution Prevention Outreach
    Pollution prevention outreach is essential to demonstrate to the community and students the importance of pollution prevention.  Annually, the Town conducts classroom and in-field educational opportunities for students, and participates in community fairs and events.
