NTMWD’s Wilson Creek Regional Wastewater Treatment Plant provides wastewater treatment under the strictest permit criteria in the State

Since the early 1970s, NTMWD has provided wastewater treatment services to its Member Cities and Customers while protecting water quality and the environment. NTMWD owns and operates four regional treatment facilities that provide secondary and/or tertiary level treatment. In addition to the regional facilities, NTMWD operates an additional 18 smaller treatment plants that are included in NTMWD’s Sewer System.

NTMWD’s Regional Wastewater System and Sewer System treated over 29 billion gallons of wastewater during the 2005-06 Operations Year (October 2005– September 2006) and treated over 34 billion gallons of wastewater during the 2006- 07 Operations Year (October 2006–September 2007). Of the total wastewater treated during 2006-07, 19% received treatment through the NTMWD’s Sewer System, while the remaining 81% received treatment at one of the four regional wastewater treatment plants.

The amount of rainfall received can result in increases or decreases in the amount of wastewater treated from year to year. In contrast to the Water System, decreases in volume of wastewater treated are seen during dry weather conditions. Treated wastewater volumes increase with heavy rain events, such as the spring rains of 2007, due to the inflow and infiltration of rain runoff through the wastewater systems.

Construction within the Wastewater System totaled more than $122 million over the last two years. Major construction projects included construction of the Sabine Creek Regional Wastewater Treatment Plant (WWTP) serving the cities of Royse City and Fate; the Muddy Creek Regional WWTP serving the cities of Murphy and Wylie; and the Panther Creek WWTP serving the City of Frisco. Enhancements also began at the Wilson Creek Regional WWTP, which serves the cities of McKinney, Frisco, Allen, Plano, Princeton, Richardson, Parker, Melissa and Fairview.

Construction and improvements to the Interceptor Systems to transport wastewater flows to wastewater plants for treatment included: Buffalo Creek, Muddy Creek, Parker Creek, Sabine Creek, and the McKinney-Prosper interceptor pipelines. Enhancements were also made within the Wastewater System with the construction of the Lower East Fork Interceptor System Force Main and Lift Station, the Plano Spring Creek Force Main and Lift Station, the Buffalo Creek Lift Station and Transfer Sewer, the Rowlett/Cottonwood Parallel Transfer Sewer, the Preston Road Lift Station, the Indian Creek Force Main, and the Beck Branch Parallel Pressure Sewer pipelines.
