King County Industrial Waste Program

The King County Industrial Waste Program (KCIW) administers regulations that allow it to give approval to discharge industrial wastewater to the King County sewer system.

Our regulations are designed to prevent businesses from discharging substances that can degrade the wastewater treatment process, harm workers or facilities, or impact water quality. Since 1969, the KCIW has required many industries to pretreat wastewater before discharging it into the sewer.

More than two decades of improvements in the pretreatment of the County's industrial wastewater -- learn more.

By working together, we can help King County recover and recycle beneficial resources, like biosolids, from the wastewater treatment process.

The program's mission statement: The mission of the Industrial Waste Program is to protect the environment, public health, biosolids quality, and King County's regional sewerage systems. We work cooperatively with our customers as we regulate industrial discharges, provide technical assistance, and monitor the regional sewerage system.

About the Industrial Waste Program provides program news and updates, updates on the program's rewards and recognition program, technical assistance opportunities and information about its advisory board.
