SIDE SEWERS - MAINTENANCE & REPAIR

Side sewers are pipes that carry wastewater from sinks, toilets and drains to the public sewer in the street. In some cases, side sewers also carry water from rooftops and gutters. Side sewers require regular maintenance and repairs to prevent blockages, leaks, and other issues. Blockages from oil, grease, and other build-ups from things like food, wipes, and hair can cause side sewers to clog and back-up. Cracks in pipes can be caused by damage or age and can lead to sink holes. Cracks also allow water from the groundwater to enter the public sewer, contributing to flooding and overflows downstream. Proper care of side sewers extends the life of the side sewer, prevents sewer back-ups, and protects the public sewer system. In Seattle, side sewers are privately owned, so property owners are responsible for maintaining their building’s side sewer all the way to the connection to the public sewer.
