Construction of the Post Point Wastewater Treatment Plant Improvements continues. Weekly construction updates are posted on the construction page. After five years of extensive planning and public process, clearing and excavation work began July 23, 2012. The project is projected to be completed during summer 2014.
The project includes adding new facilities to increase the capacity of the secondary treatment process, which will help keep the plant in compliance with state Department of Ecology discharge permit requirements. The design relies on biological processes requiring less energy to treat the wastewater.
The $55 million dollar project is the largest capital project the City has undertaken since the last wastewater plant expansion in 1993. The City's Comprehensive Sewer Plan (PDF) identifies the need for the additional capacity because the plant recently reached permitted capacity. Mortenson Construction is serving as the General Contractor/ Construction Manager through a state-approved alternative contracting method.
Mortenson, city staff and engineers from Corollo Engineers, the design firm, all work side-by side to ensure the most cost efficient, environmentally sound and socially acceptable results.
