Water Conservation

To report water leaks or sprinkler concerns, please contact East Bay Municipal Utility District (East Bay MUD) at (866) 403-2683.

Residents play an important role in keeping our waterways clean and pollution free. Even everyday activities such as driving, yard work, and washing your car can have a positive impact on our water quality.

Stormwater and all the pollutants that flow from our homes, parking lots, and streets go into the storm drain, and are discharged directly into our creeks and other water bodies without being treated.

Water and pollutants that flow into the sanitary sewer system, which are separate from storm drains, such as water from our bathtubs and toilets, are sent to a wastewater treatment facility before the water is discharged to the Bay, Delta, or ocean.

The purpose of the Clean Water Program is to efficiently utilize available funding to reduce stormwater pollution which protects our creeks and San Francisco Bay. The Town does this by operating a comprehensive Clean Water Program. The Program's activities are managed in accordance with National Pollution Discharge Elimination System (NPDES) Permit requirements are enforced by the San Francisco Regional Water Quality Control Board’s Municipal Regional Permit (MRP). The program includes:

  • Conducting educational and outreach activities
  • Operating a business inspection program
  • Implementing an integrated pest management program
  • Implementing new development / redevelopment stormwater controls
  • Performing field inspections
  • Monitoring and maintaining our creeks
  • Trash control operations
  • Maintaining the Town’s storm drain system and corporation yard activities
  • Coordination of storm drain stenciling
  • Regularly sweeping streets
  • Code Enforcement

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, developers and visitors to make sure we keep our waterways healthy. Our efforts to prevent stormwater pollution are 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.


Danville Inspection activities are completed to protect water quality and include:

  • A business inspection program
  • A code enforcement program
  • A construction inspection program


Town Maintenance activities include:

  • Application of Integrated Pest Management (IPM) practices for landscape, pond and building maintenance
  • Inspecting and cleaning Town drainage systems on an annual basis
  • Installation and maintenance of new trash and recycling containers downtown
  • 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 and Map)


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 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 residents and students, and participates in community fairs and events.
