Wastewater Treatment Plant
HR Green was hired by The City of Marengo to provide design and construction engineering services for improvements at its Wastewater Treatment Plant (WWTP). Numerous technologies were considered during the evaluation process, and with input from the City Staff, a recommended solution was generated.
The results of this evaluation led to a revised approach and final design for the WWTP that includes utilizing the sequencing batch reactor (SBR) technology followed by disk filters instead of the oxidation ditch and secondary clarifiers that were originally planned. The revised approach resulted in a much lower capital cost for the City to achieve an even higher quality effluent.
