Chastain-Skillman is providing survey, design and permitting services for a premiere mixed-use development located in Spring Hill, Tennessee.
June Lake is a premiere mixed-use development located on nearly 800-acres at the gateway to the City of Spring Hill, Tennessee. Located adjacent to I-65, June Lake is fully entitled for 2,900 homes, 3.9 million SF of commercial office space, 1.3 million SF of retail and restaurant space, and 400 hotel rooms.
Chastain-Skillman, Inc. (CS) was contracted to design and permit the water and sewer infrastructure for the development, including the Phase 1 sanitary sewer lift station. The lift station was designed to manage a peak demand of 604 gpm, with a total dynamic head (TDH) of 70.2 ft. The design was complicated by the force main having to overcome two separate high points. Ultimately, a steady-state analysis determined that the water column within the force main would start to separate at Station 14+00 and become gravity flow at Station 14+40. The lift station has a 10-ft diameter wet well and utilizes duplex 50-horsepower suction-lift Gorman-Rupp pumps. The station is equipped with an emergency bypass quick-connect fitting and valving that allows City maintenance equipment to continue to manage the demand if the pumps are offline. Services included survey, engineering design, permitting, and construction administration.
