The project will also add a solar panel system and remove decommissioned equipment that is no longer operational.

South Plant Treatment & Electrical Improvements: Eight Projects all delivered under a single construction project. Undergoing evaluation for collaborative delivery.

Sammamish Plateau Diversion: This project will address regional conveyance system capacity needs by diverting flows out of the South Lake Sammamish Planning Area north. Diverting flows northward will alleviate capacity needs at several King County conveyance facilities.
