 Construction has commenced on the City of Fort Dodge’s Wastewater Pollution Control Facility Rehabilitation Project. This project is the second of two phases of modifications designed by McClure Engineering Company (MEC) to provide capacity expansion and rehabilitation to the City’s existing treatment facility. This specific phase of work consists of major rehabilitation work to the headworks and primary treatment systems, construction of a new UV disinfection system, new anaerobic digester covers, new anaerobic digester heating and mixing system, and new back-up power generator.
Headworks improvements include a new Screening Building with two (2) mechanical step screens, two (2) vortex grit removal units, grit washing and dewatering system, raw wastewater influent metering flume, and ancillary instrumentation and control equipment. Primary treatment improvements include construction of two (2) 90-ft diameter primary clarifiers and Primary Sludge Pump Building. Effluent treatment improvements include construction of a new Final Effluent Metering, UV Disinfection, and Final Effluent Pumping Structure that allows the City to meet their newly imposed E.coli effluent limits.
Completion of construction is anticipated by the summer of 2011. At the completion of MEC’s designed improvements, the WPCF will have the ability to handle 12.0 MGD through primary treatment and 15.0 MGD through secondary treatment. The construction cost for this second phase of work is $15,570,000. The general contractor is Woodruff Construction.
