Drinking Water

Drinking Water QualityGlassWater

Redmond is part of the Cascade Water Alliance (CWA) and buys 60% of its supply from the Seattle Tolt River supply through the CWA. The rest of our drinking water supply comes from our five municipal supply wells that serve the areas of town east of the Sammamish River. The City of Redmond believes that safe drinking water is no accident - it is our highest priority - but we need your help to continue to be successful.

Redmond’s Wellhead Protection Ordinance was a major step toward protecting the approximately 40% of our City’s drinking water supply that comes from groundwater. Learn more about Redmond’s groundwater and wellhead protection program here

Redmond’s drinking water meets or exceeds all Environmental Protection Agency and Washington State Department of Health drinking water regulations. Water from each supply well is treated before it enters the City water supply system. Currently, Redmond provides three types of treatments - fluoridation, chlorination, and pH adjustment - to comply with these regulations.

WaterMeterMeters & Leaks

Our Water System Operations staff install and read water meters, locate and repair leaks in the City’s system and maintain other system components. 

We can assist in locating your water meter, reading your meter, water shut-off for emergencies, diagnosing pressure problems, and advise for tracking down system leaks. Property owners are responsible for the maintenance and repair of the service line from the meter to the home or business.

Our water meter readers are often seen working throughout our neighborhoods and business district. They read residential meters (bi-monthly) and commercial meters (monthly), then send this information to Utility Billing for processing. The readers also install and repair meters, do final reads for billing, shut-offs, meter turn-on, and other service orders.

PFAS Information

The City of Redmond’s drinking water remains safe and protected from contaminants, including the group of human-made chemicals labeled PFAS (per-and polyfluoroalkyl substances). PFAS are manufactured for a variety of industrial purposes. If detected in drinking water, PFAS have the potential to raise health concerns. For more information about PFAS, including the health and safety risks associated with these compounds, visit the Environmental Protection Agency and Washington State Department of Health websites.
