Client – City of Union
This is an on-going project for the City of Union which includes the expansion of an existing 300,000 gpd oxidation ditch. Work includes: antidegradation review, new headworks, new sludge digestion facility, new 500,000 gpd Schreiber Counter Current Aeration and conversion of gaseous chlorinated disinfection system to UV disinfection. The City of Union traditionally used chlorine gas for wastewater effluent disinfection. For safety and economic reasons, the City is discontinuing the use of chlorine gas. In addition, a new 950 gpm lift station was installed to provide for future expansion. Cochran aided in the procurement of funding for this project along with design, permitting, construction inspection and construction administration.
