The Omohundro Water Treatment Plant (OMO, WTP), owned and operated by the Nashville Metro Water Services (MWS), has been in operation for over one hundred years. Its current capacity is 90 million gallons per day (MGD). MWS is currently working with Carollo, Jacobs, and others on the Advancing Metro Water program to increase the capacity of OMO to 150 MGD. This project includes the design and construction of a new raw and finished water pumping facility, pretreatment and filtration, expanded clear well storage, and the modification of existing facilities for new purposes. As part of the raw water pumping station (RWPS), a new raw water intake will be installed in the Cumberland River. The new raw water intake screens (Intake 5) will consist of six passive half barrel screens and two 54-inch raw water intake pipes which will provide water to the RWPS at the required flows. The screens extend above a concrete scour pad to reduce the potential for fines entering the system and to encourage sediment transposition downstream. An air burst system will be provided for screen cleaning; two screens per air burst. The system will monitor differential pressure and alert operators to initiate cleaning cycles; the system will recharge the system in approximately 15 minutes. This provides the plant with the capability of cleaning all 6 screens in 30 minutes, assuming the first cleaning occurs when the compressor tanks are full. This was a critical parameter based on the increased frequency of storms and the turbidity the Cumberland River sees during these storms. Constructing Intake 5 in the Cumberland River presented several design challenges. Close coordination was required with the Tennessee Department of Environment and Conservation (TDEC) and the United States Army Corps of Engineers (USACE) to acquire a water withdrawal permit and to address minimum overdraft and other requirements. Because there is a maximum clearance of 20-feet between normal pool level of the Cumberland River and the bottom of the river, there was limited space for the intakes to meet minimum overdraft requirements. Changes in the overdraft requirements during design required changing the intake screen configuration from the initial tee screen design to the final half barrel screen design. Additional challenges included construction considerations in the Cumberland River, which is highly trafficked by recreational and commercial marine vehicles. The two new 54-inch raw water pipes that will serve Intake 5 will be installed by mircotunneling from the location of the new RWPS into the Cumberland River. To reduce impact to the marine traffic, retrieval of the mircotunneling machine and construction of Intake 5 will be performed in the wet. Since the Cumberland River is highly trafficked by heavy barges, design for impact protection was also necessary to ensure the intake would not be damaged during low water conditions.
