Private-line coordination
Irrigation piping, valve wiring, heads and control components often occupy the same shallow work zone as grading, drainage, concrete and utility projects. These are private systems, so a public utility ticket alone may not identify them. A zone-by-zone plan can reduce surprises and make repair responsibility clear.
Build a pre-work irrigation map
Record the controller location, active zones, visible heads, valve boxes, backflow equipment and sleeves. Photograph existing operation and note leaks or damaged components before the site changes. Where routes remain uncertain, discuss private locating or careful exposure rather than guessing.
Coordinate shutdown and access
Identify who can shut down the irrigation supply and controller, and keep valve boxes accessible throughout the project. An excavation plan should not bury controls or remove the only practical access route. If landscaping depends on irrigation, discuss how long the system may be offline.
Define crossings and conflict points
Compare the irrigation map with proposed trench, grading and concrete limits. At each crossing, decide whether the line will be protected, exposed, rerouted or temporarily removed. Specify compatible repair materials and who approves any change to the irrigation layout.
Test before final restoration
After excavation and backfill, operate affected zones and check valves, heads, wiring and pressure behavior before turf or hardscape conceals the work. The closeout record should show repaired locations and any changed routing so future work begins with better information.
Questions to settle before excavation starts
Will Texas811 mark irrigation pipes?
Privately owned irrigation components are generally outside the public utility locate, so separate mapping or locating may be needed.
Should every zone be tested before work?
Testing documents existing operation and helps distinguish pre-existing defects from construction damage.
Can valve boxes be covered temporarily?
Access should be maintained unless a specific approved plan provides another method.
Who pays for an irrigation repair?
The contract should define responsibility for known, marked and unknown private lines before excavation.
When should repaired zones be tested?
Test before final landscaping or paving makes the repair difficult to reach.
What if the system cannot be operated?
Document the limitation and use records, visible components and private locating as appropriate rather than assuming the area is clear.
Official planning and safety references
Use Texas811 guidance before digging. For worksite hazards, review the OSHA trenching and excavation overview. Where disturbed soil or runoff may leave the site, consult the EPA construction stormwater resource. These sources do not replace project drawings, manufacturer instructions, utility-owner requirements, or locally adopted rules.
