CONVEYANCE PIPES - MAINTENANCE & REPAIR

Sewers and storm drains collect and safely move water around the city. Sewers and storm drains are made from a variety of materials and usually last between 50 and 100 years. To ensure that pipes last as long as possible, utilities regularly clear blockages, inspect pipes, fix leaks, reline pipes, and perform other maintenance and repairs. Investing in the maintenance and repair of existing pipes prevents failures and reduces the risk of flooding and sewer back-ups. SPU owns and operates over 1,400 miles of sewer pipe and more than 400 miles of storm drains in Seattle.
