Find My M.U.D. District?
A Katy mailing address does NOT mean you are within the city limits of Katy. To determine if you are within the city limits, please refer to the map.
If you are not within the city limits of Katy, your water is provided by a Municipal Utility District (MUD). To determine which MUD district provides water to your address, please go to the Harris County website (http://www.hcphes.org/waterdb/getresults.asp) or call Fort Bend County Engineering at 281-633-7500.
