Xylem Builds Emergency Sewer Bypass in Record Time
Xylem today announced that the company recently designed and built a major emergency sewer bypass in Memphis, Tennessee in just six days.
During spring 2016, sixteen inches of rain fell on the city, half of which fell during two days. This unprecedented rainfall eroded the soil supporting a 96-inch sanitary sewer main that crossed South Cypress Creek and carried wastewater to the T.E. Maxson Wastewater Treatment Plant in Memphis. The bypass system needed to handle 160 million gallons per day of peak flow and traverse 2,400 linear feet from the suction point to the discharge location.
In response, City of Memphis officials immediately activated their Emergency Response Plan, bringing the company on board to design and develop a turnkey bypass solution to maintain sewer services, minimize the environmental impact and ensure regulatory compliance, while the main line was repaired. The project also included the construction of a 2,400-foot-long, 40-foot-wide road through swamp land, so the site could be accessed.
A team of nearly 200 people composed of Xylem engineers, Memphis Public Works, and contractor personnel worked in tandem to accelerate the project timeline. Typically, this magnitude of bypass pumping would take between two to three weeks to be designed and constructed. However, the Xylem-led team completed the emergency task in just six days.
“At Xylem we pride ourselves on being a 24/7 company,” said Ken Albaugh, Regional Director for Xylem’s pump rental business. “We’re always available with a team of people who use their expertise and experience to solve complex customer challenges every day,” “This project is a great example of how we use our in-depth experience and resources to rectify an emergency situation, while minimizing environmental impact and ensuring adherence to all regulations.”
Fourteen Godwin diesel-driven Dri-Prime CD400M pumps, two Godwin hydraulically driven CD300M pumps and nearly 30,000 linear feet of HDPE pipe were commissioned as part of the turnkey bypass, successfully pumping 60 to 160 million gallons per day of raw sewage daily.
