The City of Gallatin contracted J. Cumby Construction to complete a new Equalization Tank and Pump Station. Prior to proceeding with these structures, J. Cumby first demolished the existing structures left on the site. This demolition included the previous EQ tank and pump station from the 1950s, a large concrete slab that previously held a furniture production facility as well as hazardous material removal from the boiler room of another previous structure.
Site conditions required J. Cumby to blast rock prior to the excavation of the new Pump Station Facility.
Lastly and more notably, construction of a new Drainage Basin ‘A’ Flow Equalization Facility including a 10 Million Gallon Prestressed Tank, Concrete Structures, Pumps, Variable Frequency Drives, Piping, Valves, Meters, Concrete, Electrical, SCADA, Building, Site Work, Demolition, and all other appurtenances.
Location: Gallatin, TN
Completion Date (Estimated): January, 2022
Contract Value of $10,600,000+
Owner: City of Gallatin
Engineer: James C. Hailey 7 Co.
The inclusion of:
A 10-Million-Gallon Prestressed Concrete Tank
A Jack and Bore drilling the Sewer Line
A Pump Station that’s approximately 30’ in depth
A 42” hand bore under railroad
J. Cumby will be demolishing 20" ductile iron spool pieces, fittings, valves and installing 20" ductile iron spool pieces, fittings, valves and a 700 horsepower vertical turbine pump.
Lastly, J. Cumby will also be changing out 4ea variance frequency drives in the High Service Pump Station, as well as, 4ea variable frequency drives in the membrane pump station.
The Project consists of furnishing all labor, material, and equipment for the installation of a new high service pump, including all associated valves, piping, motor, and variable frequency drive, replacing two (2) existing high service pump variable frequency drives and one backwash pump variable speed drive, replacement of three (3) existing check valves, and the replacement of an existing PLC for the high service pump station including integration. The project also includes the replacement of four (4) existing variable speed drives for the membrane feed pumps.
Location: Murfreesboro, TN
Date Completed (Estimated): March, 2023
Contract Value of $2,013,000
Owner: City of Murfreesboro, TN
Engineer: Smith, Seckman, Reid, Inc.
The removal of the existing and installation of the new variable frequency drives must be carefully coordinated with the Stones River Water Treatment Plant which adds difficulty to the project
11930 Vertical Turbine Pumps
J Cumby Construction, Inc., will be making modifications to the existing equalization basins to include construction of a dividing wall in each existing equalization basin, which is in excess of 7 acres each, to result in four (4) new basins at the end of construction, demolition of existing process equipment and installation of new diffusers, aerators, vertical turbine pumps, blowers, water cannons with associated piping and electrical infrastructure, demolition and renovation of portions of the plan blower building and a dilution water pump station. Additionally, there will be resurfacing and repairs made to the asphalt around the equalization basins.
Furthermore, there will be approximately 10,000 cubic yards of concrete needed in order to complete the project. In Addition, the City of Chattanooga will be coordinating with J Cumby to plan out phases in which the modifications will be completed. The City of Chattanooga is needing the equalization basins to remain operational throughout the project to ensure that the WWTP can meet the system demands, as well as making sure the project can be completed on time.
Location: Chattanooga, TN

The Water Authority of Dickson County, to increase overall plant capacity and introduce more efficient treatment methods, has contracted J. Cumby Construction to upgrade and add to the Fairview Wastewater Treatment Plant in a two phase operation.
Phase one consists of the construction of new anoxic and anaerobic tanks to incorporate the use of both bubble aeration equipment and rotating mixers as well as a new headworks structure and associated underground piping and vaults. Also included in phase one are an electrical building secondary anoxic and re/air basins.
Phase two of the project includes renovation to the plant’s existing oxidation structure by adding jet aeration as well as the rehabilitation of disc aeration. A new 40’ clarifier, post aeration/UV disinfection structure, and nitrified recycle pump station will be added to the plant as part of phase two as well.
In all, the improvements will increase plant processing capacity to over 2.2 million gallons per day and create a more thorough and efficient treatment process.
