Initial CSI basin planning, 1999-2003

South Lake Washington planning area

The South Lake Washington planning area covers the Madsen Creek area of the Cedar River basin. This area includes part of the City of Renton, one of the three local service providers. Soos Creek Water and Sewer District also as well as the Cedar River Waster and Sewer District provide local sewer service in this area. The County owns and operate one interceptor, one siphon and one trunk sewer in this area. There are no County owned wastewater pump stations in this planning area.

Both the City of Renton and Cedar River WSD plan improvements in this area. This planning effort concluded that there are no major improvements in the County system needed at this time.
