Before beginning your irrigation project, contact your local water company or the proper municipal authority for information on building codes and required permits. They can also tell you about requirements for the backflow prevention devices required in your area. These devices protect your water supply from contamination and are required for inground irrigation systems.

Warning: Serious injury may result from damaging buried electrical or gas lines. Before digging or trenching, have your local utility companies mark all buried cables, pipes, and gas lines!
