Congratulations to the City of Batavia and their Project of the Year (Environmental – $25-$75 Million) Award from the APWA Fox Valley Branch presented on Tuesday, January 14th !

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%.
