Coronavirus Response

Coronavirus Update

With health officials urging closures and restrictions to public services due to the coronavirus (COVID-19), we want to assure you that your water supply is safe, and reliable.

The district’s water supply is not affected by the virus, and it continues to be safe to drink. Your water is locally sourced, with the majority of it coming from our protected Mt. Tam watershed, and it is treated, routinely tested, and monitored to ensure there are no viruses or pathogens.

We are prepared, so that under any scenario, our customers will continue to be provided with safe, high-quality drinking water. Our Business Continuity Plan includes contingencies for things such as staffing shortages, or other strains on resources.

The Centers for Disease Control (CDC) and the Environmental Protection Agency (EPA) have stated that the virus has not been detected in drinking-water supplies and that your tap water remains safe to drink. For more information from the EPA, please see

We understand that these are difficult and uncertain times. We are here, and our crews are working 24/7 so that you do not have to worry about your water supply during this health crisis. We are in this together.

Wipes Clog Pipes

Please do not flush disinfectant cleaning wipes, or "flushable" wipes. These wipes do not break down in water like toilet paper, and can damage the plumbing or cause backups. Throw wipes in the trash. Thank you!

Parking for those with disabilities is available at our Sky Oaks parking lot. While the watershed remains open, visitors must comply with social distancing requirements of at least 6 feet. All of the district’s volunteer programs that take place on the watershed have been canceled until further notice. These changes are designed to protect public health and safety during this crisis.
