SUPPLIES FOR THE FUTURE
SRP has provided a reliable supply of water to metropolitan Phoenix for more than a century.
In addition to developing new water supplies, SRP has capitalized on technology and research to stretch existing resources and encouraged conservation practices that protect this vital resource.
But our work is never done. SRP continues that work today — a constant drive to ensure water reliability for the next 100 years. Here’s how we’re doing it.
Arizona’s overgrown forests are highly susceptible to catastrophic wildfire.
In the last decade, more than a quarter of the forests in SRP’s watershed have been destroyed by fire. We are working with researchers to better understand the impacts of these catastrophic wildfires and how to effectively restore and improve forest health.

How do healthy forests affect our water supply?
A healthy forest acts as a storage and filtration system. In the winter the canopy prevents the snowpack from melting too fast. Slowing the rate at which the snowpack melts provides the Valley with a steady water supply when it is most needed – spring and early summer.
Dense, fire prone forests negatively impact water quality.
Historically, small fires were a natural part of the ecosystem in Arizona's forests, removing excess vegetation and improving soil conditions. As forest management policies changed to suppress fires, vegetation built-up leading to more catastrophic fires that scorch the soil and kill old growth trees.
Partnerships are key to forest restoration.
Restoring the health of millions of acres of forest is only possible through partnerships and funding. To begin this process, SRP partnered with the National Forest Foundation to create the Northern Arizona Forest Fund.
Conservation remains one of the most effective ways to reduce water consumption across the Phoenix metro area.
SRP has engaged in a multitude of conservation efforts, including lining canals and enhancing water delivery systems to minimize water loss by seepage.
Meanwhile, we support a host of educational programs meant to increase efficient water use. This includes our annual Water Conservation Expo and partnerships with the Environmental Protection Agency's WaterSense® and Water-Use It Wisely programs. SRP also collaborates with other water agencies.
Did you know that SRP, in partnership with municipalities and water agencies, stores water underground to protect against drought and improve water system operations?
Water banking, as the process is known, takes advantage of areas where soil conditions are just right to send water quickly back into the natural aquifers that exist beneath the Valley.
New River-Agua Fria River Underground Storage Project
The New River-Agua Fria River Underground Storage Project was completed in 2007 and is permitted to store 75,000 acre-feet per year.
Granite Reef Underground Storage Project
More than 325 billion gallons of water have been stored underground at the Granite Reef Underground Storage Project since its opening in 1994.
As the competition for water increases with Arizona’s growth, the need for collaboration will continue to grow.
SRP actively works with stakeholders throughout Arizona to address concerns about water supplies.
We’re also pursuing unique agreements to increase the Valley’s water supply. A recent agreement with the Gila River Indian Community is designed to make several million acre-feet of water supplies available to water users in central Arizona.
SRP has partnered with EPA WaterSense to promote more efficient appliances in homes and businesses. And we’re evaluating the use of technologies, such as GateKeeper, to automate control of the canals as water moves through our system.
New technologies such as desalinization of ocean water are also being explored.
