Water Quality

Bellevue Utilities designs, operates and maintains the city’s water storage and distribution system ensuring your water is safe and reliable. 

Bellevue’s high-quality drinking water comes from the watersheds of the Tolt and Cedar rivers, and meets or exceeds all state and federal drinking water standards. 

PFAS 

As a member of the Cascade Water Alliance, Bellevue’s drinking water comes from Seattle Public Utilities. Due to recent public interest, SPU offers information about polyfluoroalkyl substances (PFAS) and testing. The state Department of Health provides answers to frequently asked questions about PFAS.

Ensuring water quality

• Water storage tanks are inspected and cleaned to ensure secure and sanitary conditions. 
• City water pipes are cleaned to remove sediment that naturally collects. 
• Technology keeps water fresher by reducing the amount of time the water spends in pipes.
• Water quality testing stations located throughout the water system ensure citywide monitoring for potential contaminants.
• The cross-connection control/backflow prevention program helps to prevent contaminating fluids from going into the city’s water system.
