About Our Wastewater System



The NTMWD provides wastewater treatment services to protect the health of our communities and the environment. The water quality standards for wastewater discharges are established by the U.S. Environmental Protection Agency and the Texas Commission on Environmental Quality to protect the environment and the receiving waterways. The treated wastewater, known as effluent, is released into local waterways where it is used again to supply drinking water, irrigate golf courses, and sustain aquatic life.

 

NTMWD owns and operates four regional treatment facilities that provide secondary and/or tertiary level wastewater treatment services. In addition to the regional facilities, NTMWD operates an additional thirteen smaller treatment plants that are included in NTMWD’s Sewer System.

 

NTMWD’s Regional Wastewater System and Sewer System treated over 32 billion gallons of wastewater during the 2013-2014 Operations Year (October 2013 - September 2014). Of the total wastewater treated, 81% received treatment at one of the four regional wastewater treatment plants, while the remaining 19% received treatment through NTMWD’s Sewer System.

 

Construction contracts within the Wastewater System totaled over $171 million. The largest expenditures were incurred for the Wilson Creek Regional Wastewater Treatment Plant (RWWTP) expansion to 56 MGD and advanced treatment improvements.

 

Additional projects at wastewater plants included improvements to the Floyd Branch RWWTP odor control facilities; the Wilson Creek RWWTP gravity interceptor, Phase I and Plant II odor control improvements; the South Mesquite Creek RWWTP Plant Operations Building, aeration system improvements Phase I, electrical improvements and the Solids Building odor control system; and the Rowlett Creek RWWTP 2011 improvements.

 

Additional expansions, improvements, or rehabilitations included: the Upper White Rock Creek Lift Station, parallel force main, and metering improvements; the Cottonwood Creek outfall sewer improvements; the Forney Mustang Creek force main line C, interceptor system pressure main line D, and parallel interceptor, and Lift Station improvements; the Prairie Creek relief sewer control structure flow metering improvements; the ASAP gravity flow improvements sections 1, 2, and 3; the Upper East Fork interceptor system manhole and fugitive emissions control improvements; and the Upper Rowlett Creek and Upper Cottonwood Creek Lift Station improvements.
