What we do in Texas
Water and wastewater engineering in San Marcos
MES provides water and wastewater engineering in San Marcos and across Hays County. We design water and sewer lines, lift stations, and wastewater treatment and reuse systems for new development.
We work for developers and builders, and for cities and small water districts. For public clients, we prepare plans and reports for capital projects, including projects that seek Texas Water Development Board financing such as the state revolving funds.
How permitting and review work in San Marcos
TCEQ reviews public water system designs, wastewater system designs and wastewater discharge permits.
Part of San Marcos sits over the Edwards Aquifer recharge zone. In a regulated zone, TCEQ must approve an Edwards Aquifer protection plan before construction starts.
Discharge permits near the San Marcos River can face close scrutiny and public opposition. For sites with industrial flows, a 210E reclaimed water authorization can let the site reuse its treated water instead of discharging it to a stream.
The City of San Marcos reviews plats and site plans inside the city and provides water and wastewater service across much of it. Confirm the service provider for your tract early.
Work in and near San Marcos
In San Marcos, MES secured a TCEQ 210E authorization for a 1.0 MGD zero-discharge reuse system at a mixed-use data center development. The reclaimed water irrigates the campus and supplies fire protection.
Nearby, in Caldwell County near Martindale, MES took a 2.0 MGD mixed-use development through the 210E pathway, with the treated water reused for off-site agricultural irrigation.

Common questions
What is a 210E authorization?
It is a TCEQ authorization under 30 TAC Chapter 210, Subchapter E, which covers the use of industrial reclaimed water. The treated water is reused, for example for irrigation or fire protection, instead of being discharged.
Does the Edwards Aquifer affect my site?
It depends on where the site sits. Check the TCEQ Edwards Aquifer map viewer. A site in a regulated zone needs an approved protection plan before construction.
Does MES work with small water districts?
Yes. We plan and design water and wastewater improvements for districts and cities. Call (214) 833-6748 to talk about your project.
