PROJECT PORTFOLIO

Location: Pike Creek Sewer District Poplar Bluff, MO

Size: 10 Acres

Value: $9,558,897.00

Work will begin in March 2024 to upgrade the Pike Creek Wastewater Treatment Facility. The project will include the removal of the 2-acre lagoon Cell #3 from the existing lagoon treatment plant and the installation of a new mechanical treatment process at that location. The upgrades will begin at the terminal lift station with pump and control replacement and larger force mains to transfer sewer to the mechanical screen that will capture large solids and debris that enter the collection system. Once the water is screened it will enter the new oxidation ditch with aeration provided by large discs and then the water will be transferred to the two new clarifiers for settling. The solids from the clarifiers will be transferred to the on-site aerated sludge storage tanks and eventually land applied. The treated water will exit the top of the clarifiers and discharge through the ultraviolet light disinfection system which the final step of the treatment process.

The facility will also include the construction of an on-site laboratory and control building to allow the operators to test the efficiency of the treatment facility at the site and closely monitor the treatment of the sewage as it makes it through the plant. As part of the treatment process, there will be some piping reconfigurations so that the existing 5-acre lagoon Cells 1 and 2 will remain part of the treatment process. They will be used to handle extra flow that occurs during large storm events. The lagoon cells will be kept drawn down during low flow and then excess flow with go into those cells during large rain events. Eventually the water stored in those cells will be pumped through the treatment plant during times of low flow. This is of great benefit to the sewer district as it will allow the new mechanical treatment process to maintain normal flows so that the process continues to work effectively.
