INFORMATION/BACKGROUND
The Water Reclamation Department is currently under contract with Xylem Water Solutions, for the
purchase of Wedeco system replacement parts that are necessary to maintain and repair the City of Denton’s
ultraviolet (UV) disinfection system at the Pecan Creek Water Reclamation Plant (PCWRP). The current
contract was approved on March 31, 2020, for $550,000 with a five (5) year term and is at 96 percent spend.
Due to operational issues, it was necessary to purchase all new lamps and quartz sleeves to ensure
disinfection was operating properly to maintain effluent quality which was not accounted for in the original
amount requested. The additional spending is necessary so that the department can continue to procure
equipment and services to keep the City of Denton’s wastewater infrastructure operating as intended.
The UV disinfection system operated by the Wastewater Utility Department at the PCWRP is required by
the Texas Commission on Environmental Quality to disinfect the effluent to the bacteria limits in the
wastewater treatment facility's wastewater permit.
