What Is a MUD? Fort Bend's Water Districts, Explained
The local government behind your tap water, and how to find yours
What Is a MUD in Texas?
A Small Local Government for Water
A municipal utility district, or MUD, is a special district created under Texas law to provide services like water, sewer and drainage to a defined area. In Fort Bend County that area is usually a subdivision or master-planned community that was built outside the older city water systems.
Chapter 54 of the Texas Water Code covers how MUDs are created. A petition to create one is filed with the Texas Commission on Environmental Quality (TCEQ), and the county where the district would sit can send TCEQ a written opinion on it (Texas Legislature bill analysis). The North Fort Bend Water Authority describes MUDs as special districts created to finance infrastructure for developments, which provide water and wastewater service and look after the supply, distribution and quality of the water that comes out of your tap (NFBWA guide, PDF).
How a MUD Works
A MUD is governed by a board of directors elected by voters in the district. It pays for its water plant, pipes and drainage by selling bonds, which are repaid through a property tax that the district's voters approve.
A May 2, 2026 election order for Fort Bend County MUD 244 is a typical example. It asked voters to confirm the district's creation, elect five permanent directors, and authorize bonds and taxes for a waterworks system, a sanitary sewer system and a drainage and storm sewer system (Fort Bend County election order, PDF).
Day to day, many districts contract a professional operator company to run the water plant, take samples and prepare the annual water quality report. That's why your district's report may be posted on the operator's website rather than the district's.
Fort Bend County Runs on MUDs
Of the 186 public water systems in our Fort Bend County dataset, 128 are MUDs. Seventeen are city systems, such as Sugar Land, Richmond, Rosenberg, Missouri City and Fulshear. The rest are water control and improvement districts like Fort Bend County WCID 2 in the Stafford area, other public districts and agencies, and small private systems.
Many MUDs don't make all of their own water. They buy it wholesale:
- The North Fort Bend Water Authority, created by the Texas Legislature to address subsidence, supplies surface water to most of the MUDs and cities within its boundaries.
- Fort Bend County MUD 128 receives water from the City of Sugar Land's main system.
- Cinco MUD 5 bought groundwater from Cinco MUD 1 in 2025 and has posted notice of a change to chloramine ahead of receiving surface water.
So your mailing address can say Sugar Land, Katy or Richmond while your water comes from a MUD, and that MUD's water may come from somewhere else again.
How to Find Your MUD
- Your water bill. It names the district or city that provides your water.
- Your district's website. Most post the annual water quality report, meeting notices and any disinfectant change notices.
- Your water quality report. Every community water system publishes one each year, due to customers by July 1. It names the system and its public water system ID, such as TX0790005 for the City of Sugar Land's main system. EPA's Find Your Local CCR tool lets you search by system name or city.
- TCEQ Drinking Water Watch. Search your system's name on Drinking Water Watch to see the state's sample results.
- Ask us. Send us your address and we'll find it. Call 281-979-3405.
Why Your MUD Matters for Your Water
Your MUD, or the city or authority that sells it water, decides most of what comes out of your tap:
- Where the water comes from. Wells, surface water from the Brazos or another river, or a blend.
- The disinfectant. Free chlorine or chloramine. Districts taking surface water are posting conversion notices; see Chloramine Is Coming to More Fort Bend MUDs.
- The hardness. Two MUDs in the same city can report very different numbers; see How Hard Is Fort Bend Water?
- Which report you should read. The report that describes your water is your district's, not your city's. Here's how to read your water quality report.

MUD FAQs
What does MUD stand for?
Municipal utility district. It is a special district created under Chapter 54 of the Texas Water Code to provide services such as water, sewer and drainage to a defined area.
Is a MUD part of the city?
A MUD is its own district with its own elected board, separate from the city government. Your mailing address may say Sugar Land, Richmond or Katy while your water comes from a MUD rather than the city.
Why do I pay a MUD tax?
MUDs pay for their water, sewer and drainage systems by selling bonds. Voters in the district authorize those bonds and the property taxes that repay them.
Where can I find my MUD's water quality report?
On the district's website, usually under "water quality" or "documents", or on its operator company's website. EPA's Find Your Local CCR tool also lists reports, and you can request a copy from the district.
