Include permit and testing steps in the installation plan.
Georgetown requires a permit for a lawn irrigation system permanently connected to its water supply. The City also publishes backflow testing and documentation instructions. Build those steps into the schedule alongside trenching and equipment installation, with the exact requirements confirmed for the proposed connection and scope.
Prepare a layout that coordinates the water source, valves, planted areas and pavement crossings. If the property needs a new service or meter, identify that dependency before committing to a completion date. Include a zone record and owner training in the handover. A commercial installation should also identify responsibility for ongoing system records and access to the controller.
