1.0 MGD zero-discharge reuse for a mixed-use development

Where we work
MES is headquartered in McKinney, TX. We design water and wastewater systems for land developers in McKinney and Collin County, from capacity to permits.
MES is headquartered in McKinney. We design water and wastewater systems for developers, utilities, cities and engineering firms across McKinney and Collin County.
The work covers water distribution, sewer collection, lift stations and treatment plants. It also covers site civil design and support during construction.
Many McKinney sites start with one question: is there water and sewer capacity where the plat needs it? We answer that first. See what a McKinney utility availability study covers.
Inside the city, the City of McKinney reviews utility plans and connections. McKinney is one of the 13 member cities of the North Texas Municipal Water District (NTMWD). It is also a member of the NTMWD regional wastewater system.
In the ETJ and unincorporated Collin County, city sewer may not reach a site. Those sites need a line extension, a septic system or their own treatment plant. A plant that discharges needs a TPDES permit from the Texas Commission on Environmental Quality (TCEQ). Collin County falls under the TCEQ Region 4 office for Dallas and Fort Worth.
Outside the city, another provider may hold the water or sewer service area. The Public Utility Commission of Texas sets those areas, called CCNs. Check them before land crosses a boundary. See CCN boundaries in Collin County.
Soils matter too. Collin County sits on Blackland Prairie clay that shrinks and swells, so buried lines need bedding and joints designed for it. See shrink-swell clay in Collin County.
Near McKinney, MES designed a car wash site in Fate and a 2.67-acre office and retail center in Corinth. To the south, MES designed a 2-acre retail plaza in Seagoville. MES has also done kiosk site work in Garland.
Yes. McKinney is our headquarters. Call (214) 833-6748 to talk about a site.
It depends on the site. Some areas have a utility that holds the service area. Others have none, so the site needs septic or its own permitted plant. We check the options during feasibility.
Before you close on land or submit a plat. Capacity and line extensions drive cost and schedule. See impact fees and CIP timing in McKinney.
