Regional Versus Distributed Wastewater Treatment: A North Texas Case Study

The Greater Texoma Utility Authority contracted with Freese and Nichols, Inc. to develop a regional wastewater facility conceptual plan for the Upper East Fork Basin through 2030. As the growth in north Collin and south Grayson counties continues northward, it has become increasingly important to have a comprehensive, long term plan for wastewater service in place. The participating entities for this study include the Cities of Anna, Celina, Howe, McKinney, Melissa, Princeton, Van Alstyne and Weston. The North Texas Municipal Water District (NTMWD) currently serves as a wholesale wastewater service provider for the cities of McKinney, Princeton and Melissa and was a key member of the project team. A map of the GTUA study area is shown in Figure ES1.The scope of work for this project includes:Description of existing conditions for the planning area, such as population, wastewater flows and existing wastewater facilities.Projection of future population and wastewater flowsDiscussion on additional planning considerations, such as water conservation, water reuse opportunities, water quality, treatment plant siting and permitting, and financial and administrative issuesAnalysis of alternatives for wastewater service for the following three scenarios:Individual treatment facilitiesA single regional facilityMultiple regional facilities
