The Snake Creek Water Treatment Plant (WTP) was originally constructed in 1998 with a design capacity of 4 MDG.  Following a 2003 upgrade project, the WTP’s design capacity was increased to 6 MGD.  To keep up with the increasing water demands, Krebs was selected to begin design on a new expansion project that would increase the plant’s design capacity to 12 MGD with the ability to increase to 18 MGD in the future. 

Our team quickly got to work by performing a treatability analysis to determine which chemicals were most effective on CCWA’s raw water, while considering each chemical’s maintenance and operational costs.  With helpful participation from CCWA’s staff, Krebs proceeded with the design of the new facilities.  The design included the reuse and re-purposing of existing facilities. The reuse of facilities included a 1.5 M.G. clearwell. Clearwell improvements included new pipe connections to improve disinfection contact time and the reconditioning of the concrete exterior. The re-purpose of facilities also included the use of the packaged clarifier and filter containers as conventional filters. The filter modifications included removing the clarification systems, new filter gallery piping, valves, and actuators. The new facilities included a pretreatment basin with a rapid mix, flocculation, and high rate sedimentation with plate settlers, two additional conventional filters, chemical storage and feed equipment, 1.5 M.G. cast-in-place clearwell, finished water pump station, solids pump station and handling ponds, standby power generator, plant-wide SCADA system, and an Administration Building.

Krebs has provided construction administration services and maintained a resident field representative for the project since construction began in 2020.  The project is scheduled to be completed in the summer of 2023. 

In December of 1989, Carroll County Water Authority purchased an existing 500,000 gallon water storage tank from Brown Steel Contractors, Inc., formerly the historic R.D. Cole Manufacturing Comnpany, in Newnan, Georgia. The tank was dismantled at its current location, transported to the new site, modified to suit the water system requirements, and re-erected in 1990. As a result of increasing water system demands and needed maintenance and repairs, Krebs was selected to begin design of a new elevated water storage tank in December 2018. The design of Rainey Road Elevated Water Storage Tank No. 2 consisted of a new 500,000 gallon elevated storage tank, site piping improvements, and SCADA upgrades. Krebs provided construction inspection services during each phase of work which completed in May 2021.

Upon completion of Tank No. 2, Krebs developed a tank rehabilitation and improvement contract for the original water tank. The rehabilitation project consisted of the complete removal and replacement of interior and exterior coating systems. Krebs provided construction inspection services for installation of the new coating systems and the project was completed in April 2022.

Carroll County Water Authority’s proactive planning, design, and construction of these projects have optimized the function and resiliency of the water distribution system in the growing community.

Faced with aging infrastructure dating back to the 1920’s, the Opelika Utilities Board retained Krebs Engineering to design approximately 20,000 linear feet of new potable water piping within one of the City’s historic districts. The construction project consisted of 4,300 linear feet of 8-inch ductile iron pipe (restrained joint), 3,200 linear feet of 8-inch HDPE pipe (trenchless), 8,560 linear feet of 6-inch HDPE pipe (trenchless), 3,750 linear feet of 3-inch HDPE pipe (trenchless), installation of water system valves and appurtenances, potable water service connections, and miscellaneous abandonment and demolition of existing water facilities. The successfully completed construction project provided a significant amount of relief to the Board’s maintenance crews who were devoting a significant amount of time chasing and repairing leaks. Additionally, the project helped alleviate recurring water quality issues due to the aging infrastructure.

The Terris Tatum Tennessee River Intake Facility is a raw water intake for the Quarry Water Treatment Facility located in Madison Alabama. Krebs worked with Madison Utilities to obtain permits from the US Environmental Protection Agency, US Fish and Wildlife Service, US Army Corps of Engineers, Tennessee Valley Authority, and the Alabama Department of Environmental Management to construct the raw water intake along the shoreline of the Tennessee River and located in the Wheeler Wildlife Refuge. The intake is a permitted 29 MGD withdrawal from the Tennessee River. The intake pipeline is a 60-inch diameter pipeline which extends over 400 feet into the main channel of the Tennessee River. The Intake pipeline is equipped with two 48-inch diameter passive intake screens with an air burst cleaning system. The raw water pumping station has three vertical turbine pumps with space to add two additional pumps. The raw water pumping station currently has a firm pumping capacity of 12 MGD. The project included an electrical building with a 1.5 megawatt generator.
