Xylem to provide sustainable disinfection solution for golf course irrigation in Texas

Xylem has been awarded a $1.25-million contract to provide advanced treatment technology to the South Wastewater Treatment Plant in the city of McAllen, Texas.

MCALLEN, TEXAS, Oct. 7, 2015 -- Xylem Inc., a company dedicated to solving challenging water issues, has been awarded a $1.25-million contract to provide advanced treatment technology to the South Wastewater Treatment Plant in the city of McAllen, Texas.

The plant provides 240 million gallons of reclaimed, treated wastewater annually to the McAllen Palm View Golf Course for irrigation purposes. Xylem's technology will help to ensure consistent quality at the plant as it treats up to 10 million gallons per day (MGD) of wastewater.

Xylem's Wedeco Duron ultraviolet (UV) system will be used to disinfect the treated plant effluent prior to discharge or reuse. Pathogens potentially harmful to marine life are rendered harmless before the treated wastewater is returned to the environment or used for irrigation. By using UV technology at the plant, there is no need to store large quantities of potentially hazardous chlorine on site for effluent disinfection in the city of 130,000 residents.

The Wedeco Duron UV system was selected due to its energy efficiency, providing disinfection at the lowest power consumption. Under average flow conditions the system's intelligent autonomous lamp power adjustment and advanced sensor based control features significantly reduces the amount of power required. In addition, Xylem's Flygt Compact Submersible propeller pumps will be used to recycle water in the aeration basins. Using compact, robust direct-drive motors and fewer components, the pumps are designed for efficiency and reliability.

Xylem's Wedeco UV system will help the system to produce 10 MGD of treated water with a peak two hour flow of 31 MGD. Each UV train will handle 15.5 MGD, with a third train providing 50-percent standby capacity. The installation process at the plant began in March 2015, with the new system expected to be in operation by January 2018. CSA Construction is responsible for upgrading the plant.
