Wastewater Pump Station 13 Replacement

Project Overview

Wastewater Pump Station 13 was built in 1985 to provide wastewater conveyance for a large area of the Marymoor Business Park. In 2017 the Marymoor Business Park was rezoned from light industrial to a combination of multifamily and commercial in anticipation of the arrival of Sound Transit's Light Link Rail. Given the age of the station and the new zoning which requires the pump station system to be capable of pumping 2,000 gallons per minute peak flow, the existing needs to be replaced.
