Please call the City of Katy at 281-391-4820 to mark the location of water, sanitary sewer and storm sewer main lines. The City will only mark lines that are in the City’s right-of-way and will not mark lines from the meter to the residence/business. Please call at least 48 hours in advance.

To mark other utilities, the following steps can prevent an interruption of service or a potentially hazardous situation:

  • Call 811 (800-669-8344) before you dig
  • Give two working days notice before digging
  • Utility companies will mark the location of underground utility lines
  • Respect the utility markers and dig carefully

Homeowners and contractors who are going to undertake projects involving excavation or digging must provide at least 48 hours notice. This service will connect you with the state one call center, which will alert participating utility companies such as electric, gas, cable and phone about the planned digging so they can mark the appropriate location of their underground lines if necessary. Remember, you are responsible for marking your private lines such as invisible pet fences, sprinkler systems, yard lights and gas grill lines.
