Snake Creek Water Treatment Plant Expansion

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.
