Sending commercial septage to King County

Some businesses, commercial facilities and industries rely on septic systems to receive their liquid wastes. Many of these facilities have their septage tank wastes hauled to King County’s South Treatment Plant, the only county-operated facility that accepts these wastes.

To protect our treatment plant and its biosolids quality, King County is now requiring that businesses, commercial facilities, and industries sending septage to the county have approval to do so.

Note:This information does not apply to residential septic tanks. All waste from residences is considered domestic waste and is not regulated by the King County Industrial Waste Program (KCIW).
