Evansville Water and Sewer Utility - West WWTP Storage Basin The Evansville Water and Sewer Utility West Wastewater Treatment was completed in 2021 and was delivered with the Guaranteed Saving project involved the construction of a 6-million-gallon storage tank and 100 MGD screening facility to reduce CSO discharges into the Ohio River. Kokosing was brought on board on this project at 60% design, which allowed constructability and budgeting reviews to be performed before the project reached final design. Kokosing worked collaboratively with EWSU and the Design Team to enter into a limited notice to proceed that allowed Kokosing to secure a lease agreement for the adjacent property for staging, employee parking, and storage trailers. This saved the project approximately three months on the overall project schedule and allowed Kokosing to begin work immediately upon receiving a noticed to proceed. Plant Storage Basin project s Contracting method. This Performing your clarifier work means working within your plant while protecting and maintaining plant operations. This is a common requirement for wastewater projects and an area where customers tell us we excel. One case in point is the improvement project for the Richmond Sanitary District. Not only did we replace the clarifier mechanisms, as we will be doing for you, but we reconfigured the aeration basins and modified the influent system. The coordination between operations and construction was pivotal in maintaining the plant's effluent water quality and efficiently completing construction. Richmond Sanitary District -William E Ross Wastewater Treatment Phase I Improvements Project This $14 million -dollar project was performed to improve the plants secondary treatment process. One of the primary scopes of work involved removing the existing mechanisms and modifying the four existing clarifiers. The replacement system included one configuration change. The existing clarifiers used a double -sided weir trough located off the tank wall, allowing the flow to come up on the interior and exterior sides. The new configuration moved the trough to along the tank wall with flow coming up from only the interior side. The new trough was constructed with concrete and had fiberglass reinforced plastic baffles and v-notch weirs attached to it. With the equipment removed, the floors of the clarifiers were sounded for structural integrity. The grout layer was removed and replaced in areas identified as de -laminated or otherwise compromised. The work included replacement of the actuators on the gates of the existing distribution box. Sequencing for construction allowed one clarifier to be removed from service, requiring the remaining three to stay in operation. Isolation was achieved using the existing gates in the splitter box.
