What we do in Texas

What MES does in Anna

MES provides water and wastewater engineering for land developers in Anna and across Collin County. We size water and sewer lines for new subdivisions, design lift stations, and prepare the plans and permits that the city and the county review.

Our headquarters is in McKinney, a short drive south on US 75. We also provide site civil engineering and construction administration.

How permitting and review work in Anna

The City of Anna reviews plats and civil plans for land inside the city. For land in its extraterritorial jurisdiction (ETJ), confirm early whether the city or Collin County reviews your plat. Outside city limits, Collin County Development Services issues septic (OSSF) permits.

The city's water supply combines its own wells with treated surface water from the North Texas Municipal Water District, delivered through the Collin Grayson Municipal Alliance. Before you plan, check the Public Utility Commission of Texas map of certificated service areas (CCNs) to confirm which provider holds the right to serve your land. See CCN territory disputes in Collin County.

On the wastewater side, the city started up its Hurricane Creek regional wastewater treatment plant in 2025 and plans to expand it in phases. TCEQ permits public plants like this one, and any private plant a developer builds.

Work near Anna

In North Texas, we designed a car wash site in Fate, an office and retail center in Corinth, and a 48-lot subdivision in Lindsay with a future industrial site. For the regional picture, read our post on utility capacity planning for Prosper, Celina, Anna and Melissa.

Common questions

Who will provide water and sewer to my Anna site?

Inside the city, usually the City of Anna. Near the edges, check the CCN map first, because another provider may hold the right to serve.

Do I need a septic permit outside Anna's city limits?

If the lot will use septic outside city limits, yes. Collin County Development Services issues the OSSF permit. You apply for the county development permit first, and the septic permit follows it.
