Incorporating Sustainability into the Design of the Tri-City WPCP

The Tri-City Water Pollution Control Plant (WPCP) was placed into operation in 1986 as a conventional activated sludge wastewater treatment plant. Regional growth requires the plant to be expanded to not only provide treatment for the local area, but to serve as a regional facility for the area. Political pressures due to regionalization and the future construction of a 100M development on the properties within 100-feet of the existing property line resulted in the guiding principles established for the expansion to include cost-effective sustainable elements and appropriate site mitigation to ensure that the facility is a “good neighbor”.The project began with the development of a Site Master Plan and then proceeded with predesign and final design of the Phase I Liquids Expansion. Construction of the Phase I expansion began in September 2009 using a Construction Manager/General Contractor approach. Startup is planned for December 2010.
