Sewer Utility System

1 | 2 | 3 | 4

Wastewater that leaves the inside of your home or business enters the Edmonds sewer system and flows through city-owned and maintained pipes into the Edmonds and Lynnwood Wastewater Treatment Plants.  City staff provides maintenance and repair of City systems to ensure federal and state standards are met for water quality, plant-generated air, effluent, and solids.  The Engineering Division is responsible for the long range planning, design and construction management of public sewer system improvements and extensions.  The Sewer Division is responsible for the maintenance and operation of 14 sanitary sewer pump stations, 26 residential grinder pumps, 3,200 sanitary sewer manholes, and over 186 miles of sanitary sewer mains serving over 9,800 customer accounts.
