III. DESCRIPTION/BACKGROUND
Project Purpose
The City has identified Wastewater Pump Station No. 13 is in need of replacement as a part of the Capital Improvement Program.
Project Background
Wastewater Pump Station No. 13 was built in 1985 to provide wastewater conveyance for a large area of the Marymoor Business Park. The existing station age and equipment are beyond their useful life and need to be replaced. The pump station has been scheduled for rehabilitation in the Wastewater CIP.
