SRP Irrigation 101

Flood irrigation is a service we provide to some Valley customers. You might be wondering what it is, or how it works.

A look at the history and origins of SRP flood irrigation in Phoenix

It’s possible you’ve driven by a yard full of water and wondered why so many homes have flooded yards. You may even have heard your co-workers talk about “taking water at 2 a.m.”

It might surprise you to know that flood irrigation in Phoenix started more than 100 years ago. Early settlers designed man-made waterways known as the irrigation canal and lateral system. They carried water from the newly built Roosevelt Dam to their land in the Valley.

So how does SRP irrigation work and where does the water come from? We’re here to demystify flood irrigation in Phoenix and help you get the most out of SRP irrigation.

Where does SRP water come from?

For a full history of SRP’s water and power business, download our e-book.

At the highest elevations in northeastern Arizona, water travels through the SRP watershed made up of forests and valleys. As the water travels, it replenishes our forests and takes on essential nutrients. It then flows into SRP’s seven reservoirs, or lakes, as you may call them.

Flowing down the Salt and Verde rivers, water powers SRP’s Salt River hydroelectric pumps with sustainable energy. Finally, the water ends up in SRP’s canal system.

Ways that we deliver water:

  1. Water treatment plants receive our water and treat the raw water for customers at home and business offices.
  2. Mixing with Central Arizona Project water to meet Valley needs.
  3. Refilling water storage sites underground called aquifers, also known as water banking. This includes New River-Agua Fria River Underground Storage Project and the Granite Reef Underground Storage Project
  4. Flood irrigation in Phoenix for SRP’s agricultural, commercial and residential customers
SRP water travels approximately 150 miles from the watershed to customers in the Valley.

How does SRP irrigation get to customers?

SRP controls the delivery of more than 800,000 acre-feet of water a year. It’s moved through 131 miles of canals along with 1,000 miles of laterals and ditches.

SRP employees known as Zanjeros control irrigation gates. They direct water to the highest point of a neighborhood for delivery to customers.

After that, private neighborhood irrigation systems take over and move water to individual properties. Each system varies in design, material and maintenance.

Did you know? Zanjero

Spanish for “ditch rider” zanjeros have been critical to the success of irrigation and their communities since the late 1800s. Zanjeros carefully measure the flow and amount of water. This ensures the correct amount of water is delivered to each SRP customer at the correct time. Last year, SRP zanjeros safely drove 1 million miles with zero traffic accidents.

Once you order water, SRP will provide a date and time for your delivery. On delivery day, an SRP zanjero will open the SRP delivery gate to deliver water into the neighborhood irrigation system.

From there, the private irrigation systems owned, operated, and maintained by you and your neighbors take over.

As you can see, SRP has a long history of irrigation in the Valley, and it shows. Irrigated neighborhoods contain large trees and lush green landscapes, which instills a sense of pride in the property owners.

Irrigation is successful because neighbors work together to keep their private systems maintained year after year. Learn more about SRP irrigation, visit srpnet.com/irrigation.
