The City of Redmond’s wastewater collection system serves a residential population of over 46,000. The system is comprised of over 250 miles of sewer pipelines ranging from six inches to 36 inches, 4,000 manholes and twenty one pump stations designed to lift water from low areas into the larger gravity sewers that flow to one of two wastewater treatment facilities operated by King County/Metro.

In the City of Redmond Wastewater Department, there is a strong focus on providing high quality service, and being consistently responsive to each customer’s unique needs and concerns. Wastewater collection and treatment are among the most fundamental and essential services provided by any community; and although these services are largely invisible, they are by no means automatic. The operation of the wastewater collection system is a monumental task, and one that requires ongoing planning, maintenance and coordination to protect valuable water resources, the environment and public health.

Each year the eight member wastewater staff uses the latest technology in high velocity cleaning and television inspection equipment to protect the city’s capital investment, ensure uninterrupted service, identify potential trouble areas and verify the integrity of new installations.

Our goal is to provide service that meets the citizens of Redmond needs as efficiently and effectively as possible. For more information about wastewater collection and the sanitary sewer system, or to report a problem call 425-556-2800.
