FOR IMMEDIATE RELEASE: Tuesday, July 25, 2006

Bellevue scores high again in water quality report

Drinking water in Bellevue remains safe for consumption. According to the 2006 Water Quality Report, prepared in accordance with the federal Safe Drinking Water Act, Bellevue’s drinking water meets or exceeds all state and federal drinking water standards. Both the

Treating Water For Safety

The City of Bellevue acquires water from Cascade Water Alliance, a regional water supplier.  Cascade, in turn, purchases water from the City of Seattle, which manages a large supply that originates from the Cedar and South Fork Tolt rivers in the Cascade Mountains. Both Bellevue and Seattle collect water samples annually and send them to laboratories that perform stringent testing.  The water has always passed federal standards.

City water is treated both to ensure that it is safe and to improve its taste and odor.  Water from the Cedar River is screened, flouridated and disinfected with chlorine and ozone.  A small amount of lime is also added to control corrosion to pipes.  Treatment for water from the Tolt River includes ozonation, filtration, flouridation, chlorination and pH and alkalinity adjustment.

Sources of Drinking Water

Residents in the Enatai, Somerset, Woodridge and Meydenbauer neighborhoods typically drink water from the Cedar River.  Residents in other areas of Bellevue drink water from the Tolt River. Cascade Water Alliance purchases the water from Seattle and provides it to Bellevue and other members in a cost-effective and environmentally sensitive way.

To meet our region's growing need for water, Cascade is working to develop new sources of water for the next 50 years and beyond. Cascade recently completed a contract to purchase water from the City of Tacoma and will be constructing the infrastructure necessary to link the two systems.

Source Water Assessment

The state Department of Health has conducted a source water assessment for the Cedar and Tolt River water supplies, as required by the federal Safe Drinking Water Act.
