How flood irrigation works
Where does the water come from?
Most irrigation water originates from SRP's — an area of land that channels rain and melted snow into the Salt and Verde rivers.
How SRP manages the system for delivery
SRP controls the delivery of nearly 800,000 acre-feet of water a year that travels through 131 miles of along with 1,000 miles of laterals and ditches. SRP employees known as zanjeros (Spanish for “ditch rider,” pronounced sahn-hair'-ohs) control irrigation gates and direct water to the highest point of a neighborhood for delivery to cities and irrigation customers throughout the Valley. After that, private neighborhood irrigation systems take over and move water to individual properties. Each system varies in design, material and maintenance.
Roles and Responsibilities
SRP
SRP brings irrigation water to the SRP delivery gate.
On delivery day, an SRP zanjero will open the SRP delivery gate to release water into your neighborhood.
From there, the water is carried to your property through a series of ditches, channels or pipelines that are owned, operated and maintained by you and your neighbors.

Water conservation
Irrigation allows trees to grow strong roots and create larger umbrellas of shade coverage. As a local utility strongly rooted in Arizona, SRP is committed not only to irrigation as a vital source of water for the Valley but to conserving water for the future. We’ve held conservation at the heart of our water management strategy for more than a century. This is why we partner with cities on water technology and pilot programs and have even set a goal to save 5 billion gallons of water, all so we can ensure a long-term, reliable water supply for the Valley.
