Welcome to the City of Katy. Prior to having water/sewer/garbage services connected, you must complete an Application (see link below) and pay a deposit. Residential service deposit is $100 and commercial deposits are dependent upon meter size. The City retains this deposit as long as the account is active. A driver’s license or photo identification must be presented at time of application or a copy may be sent if making application by mail or fax. When moving, please complete the Request to Disconnect and any refund due to you will be sent to your forwarding address.

For commercial accounts, a Letter of Intent for use of the commercial property must be attached to the application. Water service will not begin until approval has been given from the Zoning, Building and Code Enforcement Departments.

Water Account Information

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, your water is provided by a Municipal Utility District (MUD). To determine which MUD district provides water to your address, please call either Harris County at 713-439-6260 or Fort Bend County Environmental at 281-579-4500.

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.

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.
