The City of Batavia is located along the Fox River in southern Kane County, approximately 35 miles northwest of downtown Chicago.  The City is bordered by the City of Geneva to the north, the Fermi Lab to the east, the City of North Aurora to the south and the unincorporated Batavia to the west. The City’s Wastewater Treatment Facility (WWTF) is located on Shumway Avenue on the western shore of the Fox River, approximately three-tenths of a mile south of the Wilson Street Bridge.  The treatment facility has a design average treatment capacity of 4.2 million gallons per day (MGD).  The facility provides preliminary, primary, and secondary treatment for flows received from the tributary communities to meet strict effluent water quality requirements before discharging to the Fox River.

This project is the first of three phases to upgrade the City of Batavia’s WWTF. The proposed footprint of the future Phase II structures required the relocation of several major systems in the plant during Phase I; A Main Building was constructed for administration/lab, maintenance garage, the plant’s main switchgear, and sludge dewatering – This building utilized rammed-aggregate piers for foundation support; A Digester Operations Building was constructed for an intermediate pump station and digester heating, mixing and transfer systems which required shoring and bedrock removal; Rehabilitation of the Anaerobic Digesters; Ferric Chloride feed and storage systems for chemical phosphorus removal; Rehabilitation of excess flow disinfection. Equipment failure during construction required an emergency bypass of the Facility for replacement of three slide gates.

The City implemented temporary odor control within their existing Sludge Handling Building while they were without digestion for over a year.  Project change orders were under 2%.

The City elected to fund the project through the Illinois EPA’s State Revolving Fund program. Utilizing the low-interest loan program the City maintains an extremely efficient facility producing a consistently high-quality effluent. This long-term planning has allowed the City to stay ahead of regulatory requirements by utilizing a sustainable funding source.
