Our regulations are designed to prevent businesses from discharging substances that can degrade the wastewater treatment process, harm workers or facilities, or impact surface-water quality. Since 1969, the KCIW has required many industries to pretreat wastewater before discharging it into the sewer.
Protecting water quality is a sound business investment. The region is committed to improving its natural resources, including water. This means that businesses and regulators must work together to find better ways to manage waste.
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 information about customer news and updates, our rewards and recognition program, technical assistance opportunities and our advisory board.
