To have the location of water, sanitary sewer and storm sewer main lines marked, please fill out the Locate Service Request form (link below) and email to Planning@CityofKaty.com or submit in person at Katy City Hall. The City will only mark city lines.  The city does not mark private service lines.  Please submit request 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.
