Horse Racetrack bets on Flygt for pump station design

USA

Challenge
In the mid-1990s the New Jersey Sports and Exposition Authority (NJSEA), which previously owned and operated the racetrack, constructed facilities to collect horse wash water and first flush stormwater runoff for conveyance to the Two Rivers Water Reclamation Authority (TRWRA), a wastewater treatment facility located in Monmouth Beach. At that time, TRWRA could only accept up to 125,000 gallons per day. Runoff volumes often exceeded that amount, resulting in direct discharge to Branchport Creek.

Solutions
The design concept was from the NJSEA and executed by consulting engineer, Paulus, Sokolowski & Sartor (PS&S). Among the key elements of the plan was construction of a new stormwater pumping station to pump 500,000 gallons of stormwater per day generated in the backstretch area, track, parking areas, and grandstand to TRWRA for treatment using two Flygt 20-hp NP3153 submersible pumps each rated for 1,900 gpm, pump excess volume of stormwater to the Elkwood Basin using five 250 hp Flygt CP3501 submersible pumps each rated at 19,300 gpm, and conveyance of the stored stormwater in the Elkwood Basin to TRWRA for final treatment during dry weather using two additional Flygt NP3153 pumps.
