The filtration system improvements proved to have many challenges including the overall age of the facility. Equipment and components of the facility were well beyond their normal design life and were failing to operate as designed.

CT’s scope of work included preliminary engineering to determine the best location for the PAC equipment and detailed design of required site work, structural, mechanical, plumbing, electrical, and architectural components.

The team of CT and URS designed a 7.1 MGD water treatment plant with expansion capability to 13.0 MGD, consisting of both groundwater and surface water treatment systems, adjacent to the existing plant which will be used for pretreatment.

The project involved replacing four vertical turbine raw water pumps with capacities ranging from 8 MGD to 15 MGD at 40 ft TDH.

CT provided design and construction contract administration services for the 3-phase upgrading of the City’s 2.8 MGD water treatment plant.

The most significant improvement at the WWTP is the addition of a High Rate Treatment (HRT) facility. The new HRT system will comply with NPDES permit requirements issued by Ohio EPA to address CSO overflows near the plant. This $25 million project will be completed 4th quarter 2021.

Expected to be completed by Fall of 2021, this project includes the installation of a flow diversion chamber that intercepts plant bypass flow and redirects it to Primary Clarifier Tanks. Operationally, once both clarifiers are full, bypassed flows exceeding the capacity of Primary Tanks 3 & 4 are conveyed to existing Aeration Basins 5 & 6 (that have been converted to Secondary Equalization service) via a new 9.3 MGD Transfer Pump Station and 24-in. force main.

The County desired to expand the plant from 2.5 MGD to 6.0 MGD to handle the projected growth within the service area.

CT evaluated the feasibility of constructing MBR activated sludge in lieu of other selector processes to meet future phosphorus and nutrient requirements.

The Pickaway Correctional Institution’s (PCI) wastewater treatment plant has seen an increase in flow due the regionalization of the plant to serve the prison. The expansion accommodated an increase in daily wastewater flow from 1.4 to 2.4 MGD.

CT prepared a construction sequencing plan that would allow the WPCF to remain fully operational throughout the construction process.

The construction included a waste activated sludge holding tank for seeding the high flow Oxidation Ditch for peak flow secondary treatment. The improvements included site piping, level sensors and meters to control pumping stations and flow splitting weirs, gates and valves.

Due the age, condition, and operations, the two existing tricking filters and associated equipment required upgrade and replacement.

CT prepared a facilities plan resulting in a recommendation for the construction of a second wastewater treatment plant designed to relieve the overloading occurring at the existing Black River Wastewater Treatment Plant.

Improvements include: pretreatment building modifications and improvements consisting of new grit receiving pad, new electrical additions, mechanical bar screen; pump station modifications including the replacement of the pumping and pump controls, and miscellaneous piping; equalization basin improvements that include installation of a new bar screen and washer-conveyor; aeration basin and control building improvements.
