Project Description: The main Lift Station transferring wastewater from the City of Temple to the Temple-Belton WWTP via a 30-inch force main is the Shallowford Lift Station. The existing station was constructed in the 1970’s and had reached its capacity. Likewise, the existing force main was nearing capacity. A preliminary study was prepared and recommended constructing a new station approximately 1,000 feet to the east of the existing and paralleling the existing 30-inch force main with a second 30-inch force main.
KPA prepared plans and specifications for the relocation and expansion of the Shallowford Lift Station. The “New Shallowford Lift Station” is capable of transferring up to 38 million gallons per day (MGD) of wastewater. The Lift Station consists of six (6) 200 HP submersible pumps on VFDs, two (2) Emergency Generators and associated piping, valves, electrical and SCADA improvements. The incorporation of VFDs allows the six pumps to be equally sized and interchangeable in the operational scheme. The wet well is constructed as two separate basins that can be operated independently or together (for future maintenance purposes). The Station incorporates magnetic flow meters and electric operated plug valves to allow flow to either of the 30-inch force mains or both at peak flows. This allows the existing 1970 force main to remain in operation at normal flows and incorporate the new force main at higher or flushing flows, while maintaining TCEQ minimum flow velocities. The lift station project included approximately 1,000 LF of 30-inch Force Main and a connection to the existing Force Main.
A separate construction contract allowed the installation of approximately 10,000 linear feet of 30-inch Force Main, including 1,300 LF of 30” pipe by directional drill under the Leon River.
Scope of Services: KPA provided Preliminary and Final design, permitting, coordination with City of Temple, City of Belton, Bell County, Atmos and ONCOR, construction administration, onsite representation, easement preparation, Opinion of Probable Cost, Bidding, Review of bids and Recommendation to Award Contract, On-Site Representation and Construction Administration of three separate construction contracts.
