As part of the Lake Hills Sewer Relining Project, King County will install pipe lining along approximately 7,200 feet of the 48-inch and 54-inch diameter concrete pipe. We will use a spiral wound technology, which allows crews to rebuild the pipe from the inside. Crews can feed the spiral wound lining in through maintenance holes, which speeds up the construction process and helps to minimize impacts to the community by repairing the pipe in its current placement.
The pipes need to be dry during lining, so we will need to reroute existing wastewater into a smaller temporary pipe. This temporary pipe would likely be routed above ground along streets, partially trenched, or be outfitted with ramps to help people and vehicles safely travel across. Construction is expected to take up to six months.
