The Division of Engineering and Division of Utilities are requesting the Board of Public Works'
approval of the Title Sheet and Request to Advertise for Project No. 119-069 WWTP Secondary
Treatment and Disinfection Improvements.
Background
The City of South Bend Long Term Control Plan and Consent Decree (May 2012) requires the
Wastewater Treatment Plant provide Secondary Treatment for 100 MGD peak flow rates. As part of
this effort to upgrade the facility, Secondary Clarifiers, Aeration Basins, and Disinfection facilities
require upgrades to improve the hydraulics and return activated sludge return rates to optimize
treatment capacity.
The engineering scope for the WWTP Secondary and Disinfection Improvement project will address
the following major improvements:
• Final Clarifiers 1-5: Replace sludge mechanism, drive motors, access walkways, isolated
structural improvements, rehabilitate weirs, and replace handrails.
• Aeration Basins 1-4: Replace Pass 1-2 Influent Gates and the drain gates at Aeration Tank
4.
• Aeration Basins 1-4: Extend the length of the Aeration Basin effluent weirs.
• Disinfection Building and Chlorine Contact Tanks: Increase capacity of chlorine and sulfur
dioxide gas systems by adding evaporators, scrubbing equipment, and improvements to
distribution piping.
