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

Where we work
Water and wastewater engineering in Garland, TX. MES designs utility connections, studies aging pipes and I&I, and plans pretreatment for city review.
MES provides water and wastewater engineering and site civil design for projects in Garland. We work for developers, utilities, municipalities and engineering firms. MES is headquartered in nearby McKinney.
Garland is a mature city, so much of the work fits new demand onto existing pipes. That means checking main capacity, designing service connections and planning sewer tie-ins the city will accept.
For utilities, MES also studies aging systems. That includes infiltration and inflow (I&I) and water loss, ranked into a plan for repairs and replacements.
Garland sits mostly in Dallas County, with small parts in Collin and Rockwall counties. The City of Garland reviews private development plans for streets, drainage and utilities.
Garland is a member city of the North Texas Municipal Water District (NTMWD), which supplies its treated water. The city runs its own wastewater system, with the Rowlett Creek and Duck Creek treatment plants. Both discharge under TPDES permits from the Texas Commission on Environmental Quality (TCEQ).
Industrial users face one more step. A significant industrial user needs a wastewater discharge permit from the city's Industrial Pretreatment Program before it discharges. The city asks for the application at least 90 days ahead.
TCEQ's design rules apply statewide. Public water systems follow 30 TAC Chapter 290. Wastewater systems follow 30 TAC Chapter 217.
MES is working on a drive-up water kiosk site in Garland now, as part of a multi-state kiosk site program.
Elsewhere in Dallas County, MES designed a 2-acre retail plaza in Seagoville and a site master plan in Hutchins. Farther east, MES did the civil design for a car wash site in Fate.
It depends on what you discharge. The city requires a permit for significant industrial users. That covers users under federal categorical standards and users that discharge 25,000 gallons per day or more of process wastewater. The city can also designate a user. MES can help characterize the wastewater and plan pretreatment.
Yes. MES quantifies I&I and water loss and turns the results into a ranked replacement plan. One example is an I&I and water loss study in Oak Creek, Colorado.
