Payment is due to our office on or before the 16th of each month.

All meters are read electronically and utility bills are mailed on the last day of the month. A penalty is assessed on the 17th (or the next business day). A late notice, with the penalty included, is mailed on the 17th to all outstanding accounts. This notice serves as a cut-off notice and must be paid by the end of the month to avoid service disconnection.

By ordinance, any bill left unpaid 10 days after penalty will be turned off for non-payment and will be charged a $50 disconnect/reconnect fee.


IMPORTANT: A Katy mailing address does NOT mean you are within the city limits of Katy. To help determine if your address is in the jurisdiction of the City of Katy, please refer to the map before completing an application for service. If you are not within the city limits, your water is provided by a Municipal Utility District (MUD). To determine which MUD provides water to your address, please contact the HOA in your neighborhood or go to the TCEQ map and follow the steps below:

  1. Type your address and city in the search bar
  2. Once your address is found, hoover over the water drop icon below the address bar
  3. Clicking on the icon will open the information in a separate window
