Irrigation defined

Irrigation, or flood irrigation, is the most cost-effective way to deep water your property. Yards are flooded with two to three inches of water that penetrates the ground in three to four hours.

Where does the water come from?

SRP brings water from the high country to the desert below through a complex system of dams, lakes, canals, laterals, ditches, pipes and valves.

An map of the SRP watershed.Most of your water originates as rain or snow in the mountains. The SRP watershed is a 13,000-square-mile area draining into the Salt and Verde rivers. The watershed extends from the White Mountains near the New Mexico border to the Seligman area in north central Arizona.

The runoff from the watershed is collected in six reservoirs: four on the Salt River and two on the Verde River.

SRP's system also includes about 250 groundwater deep-wells throughout the Valley that help us meet shareholders' needs.

From the reservoirs to your yard

So how does the water get from the reservoirs to your yard? SRP uses the most cost-effective, efficient water transmission method available: gravity. Canal water is moved almost entirely by Mother Nature.

After you place your water order, we combine it with all the other water orders from the Valley, and release the requested amount of water from the storage dam. The water then flows into the seven main canals crossing the Valley.

An SRP employee known as a "zanjero" (pronounced sahn-hair'-oh) opens a gate to release the water from the canal into a system of smaller waterways called laterals. The lateral brings the water to a specific delivery point where a zanjero opens SRP's gate, releasing the water into your neighborhood.

The neighborhood delivery point is the end of the SRP system. From here, the system bringing water to your property is made up of open ditches, underground pipelines, control gates and valves. This system is owned, operated and maintained by the people who use the system in your neighborhood and is referred to as the "private system."

You and your neighbors are responsible for seeing that the water gets from the SRP delivery point to your property. To do this, make sure all gates and controls are set properly and keep the system in good repair.

Tips

  • If you are new to irrigation, the best way to learn about your neighborhood system is to talk to your neighbors. Also, one of SRP's Customer Service Field Representatives can visit you for a walk-through. Contact the Water Customer Service Office at (602) 236-3333 to request this orientation.
  • Get to know your neighbors, and encourage team-work. Successful irrigation depends on neighbors communicating and working together. By knowing your neighborhood system and how it works, you'll be able to prevent and solve problems.
