Booster Stations… For Wastewater Conveyance?

Kimley-Horn assisted the JCUA with securing a Water Pollution Control Revolving Loan Fund (WPCRLF) project for the design, construction, and expansion of a regional wastewater transmission system. The design included an in-line pressure reducing station, a new triplex submersible station, and the decommissioning and abandonment of existing pump station infrastructure. The project consisted of the design of the following items: • A triplex wastewater submersible pump station (3,200 gpm capacity). • Replacement of approximately 2,300 linear feet of 24-inch diameter force main. Approximately 900 linear feet of the FM was installed via horizontal directional drill. • Replacement and extension of approximately 1,300 linear feet of gravity sewer piping. • 1,000 lf of 8-inch diameter slip-lining. • A triplex inline wastewater pressure reducing station (6,000 gpm capacity). • Bypass piping on the 24-inch diameter force main to allow for flow to be directed around the inline wastewater pressure reducing station. These improvements were necessary to help alleviate the pressure and capacity issues in the Washington Avenue 24-inch diameter Force Main. The design considered both dry weather and peak wet weather flow events, impacts to other pump stations connected to the Washington Avenue force main, and design provisions for accommodating the flow conditions.
