What we do in Texas

What MES does in Katy

MES provides water and wastewater engineering for projects in Katy, from residential subdivisions to commercial and retail sites. We work for developers, municipal utility districts (MUDs), municipalities and civil engineering firms.

The work covers water and sewer lines, lift stations, treatment and the site civil plans that go with them. In Katy, drainage and detention shape a site as much as the utilities do, so MES plans them together.

How permitting and review work in Katy

The City of Katy sits where Harris, Fort Bend and Waller counties meet. Many homes and businesses with a Katy address are outside the city limits. So the first question is who reviews the site.

Inside the city, the City of Katy reviews development plans. In unincorporated Harris County, the Office of the County Engineer handles permits, and the Harris County Flood Control District oversees the regional drainage system.

Outside city limits, water and sewer service often comes from a MUD. MUDs operate under Chapters 49 and 54 of the Texas Water Code. The Texas Commission on Environmental Quality (TCEQ) reviews MUD creation and supervises district bonds.

Groundwater use is limited by the Harris-Galveston Subsidence District in Harris County and the Fort Bend Subsidence District in Fort Bend County.

TCEQ sets the state design rules for water (30 TAC Chapter 290) and wastewater (30 TAC Chapter 217). It issues TPDES permits for treatment plants that discharge.

Work nearby

MES has completed civil site plans for two drive-up water kiosk sites in Katy and more across Houston. They are part of a multi-state kiosk site program where MES prepares the plan sets and answers the review comments.

Common questions

Is my Katy site inside the city limits?

Not always. A Katy address can be in the city or in an unincorporated part of Harris, Fort Bend or Waller County. MES confirms the jurisdiction first, because it sets the drainage rules and the review path.

Does my site need detention?

Usually. Harris County requires new development in unincorporated areas to offset the extra runoff it creates, most often with detention. MES runs those numbers early so the pond fits the site plan.

Do you work with MUDs?

Yes. MES works with land developers and districts on water, sewer and treatment design. See our MUD developer partnership.
