Public Notice - Your Tap Water is Safe to Drink

Three Valleys Municipal Water District responds to the COVID-19 emergency

March 20, 2020

Three Valleys Municipal Water District (TVMWD) is closely monitoring public health recommendations related to the coronavirus (COVID-19) pandemic and taking precautions to protect the well-being of our employees and the public.

The water we treat and deliver to our 14 member agencies across eastern Los Angeles County remains safe to drink and use. Our supplies of local groundwater and imports from the Metropolitan Water District of Southern California (MWD) are not impacted by COVID-19. Additionally, the state-of-the-art treatment process at our Miramar plant and MWD’s Weymouth facility ensures our water meets or exceeds all state and federal health and safety regulations.

TVMWD is fully prepared to respond to this pandemic and maintain operations to avoid any service disruptions.

As a wholesale provider of supplemental water to the region, TVMWD does not serve the public directly. To do our part to combat the spread of the virus, we have closed our offices to the public, and administrative staff is working from home when possible. The personnel who regulate and treat our water supplies and maintain the system continue to work so we can ensure safe water and uninterrupted service to more than 525,000 people served by our member agencies across 133 square miles.

TVMWD is committed to maintaining high-quality water and customer service as well as protecting public health during these trying times.


Three Valleys Municipal Water District's mission is to supplement and enhance local water supplies to meet our region's needs in a reliable and cost-effective manner.

A District of Distinction

Three Valleys Municipal Water District Receives the "District of Distinction" Accreditation
The Three Valleys Municipal Water District (TVMWD) was awarded its initial District of Distinction accreditation in 2014 by the Special District Leadership Foundation (SDLF) for its sound fiscal management policies and practices in District operations. TVMWD was reaccredited for another two years in June 2016.
SDLF provides an independent audit review of the last three years of the district’s operations to ensure prudent fiscal practices,” said Neil McCormick, SDLF Administrator. The committee members who review the audits are volunteers from the special district community, including district controllers, directors of finance and certified general managers.
In addition, the District’s board of directors and executive staff must also show proof of educational training in public governance, as well as compliance with ethics and harassment prevention training.
