About Us: The North Texas Municipal Water District (NTMWD) is a regional provider of water, wastewater and solid waste dispos ... al services. The NTMWD serves a population of about 1.8 million residents in 80 communities across the north Texas counties of Collin, Dallas, Denton, Fannin, Grayson, Hopkins, Hunt, Kaufman, Rains, and Rockwall – a service territory covering 2,200 square miles. History: In 1946, local leaders from ten cities formed the Tri-County Reservoir Association (TCRA) to work with the U.S. Army Corps of Engineers to build Lavon Lake for flood control and water storage. By request of the TCRA, the Texas Legislature authorized the formation of the North Texas Municipal Water District (NTMWD) in 1951 to develop, finance, construct, and operate facilities to meet future water needs for the region. The 10 original cities - Farmersville, Forney, Garland, McKinney, Mesquite, Plano, Princeton, Rockwall, Royse City, and Wylie - became the original Member Cities, each with representation on our Board of Directors. Three additional cities were added including Richardson (1973), Allen (1998), and Frisco (2001). We also provide treated water service to 33 Customers (cities and other special/municipal utility districts) and indirectly serve 46 other communities who purchase water from our Member Cities and Customers. We began offering wastewater treatment services in the 1970s and solid waste disposal services in the 1980s. We also operate the largest man-made wetlands in the country - a vital water reuse project that helps to naturally polish treated wastewater, supplement our water supplies, and supports a valuable ecosystem to the region.
