Be aware that only the buried facilities registered with Iowa One Call will be located and marked. All owners and operators of buried facilities, including public and private utilities, used in the storage, conveyance or provision of services, must register with Iowa One Call. Currently there are more than 1,500 registered members in Iowa. Private facilities not registered with Iowa One Call will not be marked for locates. Private facilities include LP gas lines, sprinkler systems, gas grill lines, invisible dog fences and any buried cables, wires or plumbing installed by the current or previous homeowners.
Homeowners may call private locating companies to have their private facilities marked. While all locates provided through the Iowa One Call notification system are free of charge, private locating companies will charge the homeowner for the locating process. Keep in mind that some buried facilities, such as plastic lines without tracer wires may not be located with conventional locating equipment and will not be marked. For private locating companies in Iowa refer to Great Plains Locating Services, Vannguard Utility Partners and OCL of Iowa under the Related Links page.
Please note that some utility companies may only mark their facilities up to the termination point, point of attachment or service entrance – not all the way to the house or other structure. Iowa law requires facility owners and operators to mark only the portion of the buried facility that they own and maintain. While many facilities terminate at the house, such as gas, electric, telephone and cable TV, some facilities may terminate at a service entrance under the street, point of attachment on a utility pole or other location. An example may be the water utilities in your area. Lateral sanitary sewer lines (from the house to the street) are the property of the homeowner and not owned or maintained by the city, sewer or water utilities.
