The following private utilities will not be marked by Texas811: gas lines extending from the meter to the house, main water lines, sprinkler pipe, sprinkler wire, septic systems, swimming pool water lines, swimming pool gas lines, swimming pool electric lines, electric lanterns, gas lanterns, propane tanks/lines and landscape lighting. It is the customer’s responsibility to have each of these private utilities marked by a professional to prevent damage. A casual mentioning of the location of the private utilities by the homeowner will not be sufficient. Treeland takes no financial responsibility for repairs or reimbursing the customers for their costs when private utilities are not marked or not marked correctly (utilities that are within one foot of either side of the markings are located correctly). If the private utilities are marked correctly and they are damaged, then Treeland will take financial responsibility for repairs or reimbursing the customers for their costs.
