Celebrating 70 Years
Providing clean, fresh drinking water has been our top commitment for the past 70 years.

The story of Sammamish Plateau Water began in 1945, more than 50 years before the City of Sammamish was incorporated, when voters approved to establish a local water district. By 1948, King County Water District 82 was providing water service to 35 residents in the northwest corner of Pine Lake. Today, Sammamish Plateau Water operates 12 wells, encompasses an area of 29 square miles, and provides water and sewer services to a population of approximately 64,000 people within Sammamish, Issaquah, and parts of unincorporated King County.

As we celebrate this milestone anniversary, we reaffirm our promise of providing a quality of drinking water that is the expression of the communities we serve. It is also great time to recognize the dedication of generations of Sammamish Plateau Water and Sewer District employees and leadership in planning for, constructing, maintaining, and ultimately replacing our complex distribution systems that provide an essential resource for our customers.
