The county is continuing design on an underground wastewater storage facility in the City of Black Diamond that will extend the life of existing equipment and defer the need to build additional new conveyance pipes and pumping facilities for several years.
This project will expand capacity in the rapidly growing south portion of King County’s service area by adding approximately five miles of pipes in Kent, Auburn, Algona and Pacific. The county will complete final design and advertise the first phase for construction in 2009.
