Welcome to the City of Katy
To determine if you are within the city limits, please refer to this map before completing an application for service. A Katy mailing address does NOT mean you are within the city limits of Katy. If you are not within the city limits, 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 or click here for the Fort Bend MUD map.

All meters are read electronically as close to the 15th of each month as possible and utility bills are mailed on the last day of the month. Payment is due in our office on or before the 16th of each month and 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.
The utility billing rate schedule can be viewed by clicking the link below.
There is a payment drop box located in the courtyard of City Hall. Payments that are in the drop box by 8:00 a.m. on the first working day after the 16th will be considered timely. We do not consider the postmark on mailed items. Please allow mail time for online bill payments, we are not set up to accept electronic payments. The City of Katy offers the service of automatic payment of water bills by drafting your bank account each month on the 16th. This service is provided at no charge.
The City of Katy has maintained a Superior Water District rating for the past 20 years and is dedicated to continuing this service to the citizens. The report below is a summary of the quality of the water we provide our customers.
