Expansion of Wastewater Treatment Plant
Montville, CTThe Town of Montville's wastewater treatment plant, which provides municipal sewerage service to the Mohegan Sun Casino, required major upgrades to handle increased the loads generated by the casino. The Town turned to FST to complete the needed improvements on a fast-track basis.
FST developed a comprehensive preliminary design report to assess the impacts of the casino discharge to the WPCF, and prescribed an innovative capacity upgrade. Preliminary design was completed in less than a month. The report addressed the hydraulic, organic, and solids loading capacity of the secondary treatment facility, which used Sequential Batch Reactor (SBR) technology.
The developers and the Town accepted FST's recommendation to gain the needed capacity by converting the coarse bubble diffused aeration system in all three SBR units to a more efficient and cost-effective fine bubble system. FST was given the green light to complete final design, prepare contract documents, and provide onsite inspection. The intensive design effort was completed in less than two months, meeting the Town's intensive schedule.
