At SRP, water awareness is always top of mind. For more than 100 years, we’ve been hard at work building relationships, integrating new technologies and developing more infrastructure to ensure a resilient water supply in the desert we call home.
Learn where your water comes from, what we’re doing to protect it and how you can help.
Discover where your water comes from
SRP manages and delivers about half of the Valley’s water supply.
Water originates from a 13,000-square-mile watershed and then travels through the Salt and Verde river systems, reservoirs, canals, irrigation laterals and water treatment plants to reach you.
The rest of the Valley’s water comes from the Colorado River, wells and other sources.
Planning for droughts and floods
For nearly 120 years, SRP has provided a reliable water supply despite our desert conditions, dry winters, floods, monsoon downbursts and hot summers.
Through strategic planning, development of infrastructure, data collection and analysis and research, we’ve been able to keep our water supply resilient and reliable despite harsh climate conditions.
Building a water supply to last for generations
We have a variety of projects dedicated to building and protecting the Valley’s water supply today and tomorrow, including:
Storing surface water in dams
Six dams on the Salt and Verde rivers and one on East Clear Creek allow SRP to store water for use during drought. Dams are constantly monitored and managed to maximize water supply.
Storing water underground
SRP works with Valley cities and towns to store water underground through the Granite Reef Underground Storage Project (GRUSP) and the New River-Agua Fria River Underground Storage Project (NAUSP).
Measuring snow and water flow
SRP measures water flows with tools like SRP Flowtography® and SRP Snowtography®.
Adapting to climate change and uncertainty
We also research the impacts of climate change to the hydrologic cycle with partners in academia to better prepare for the future.
Keeping all Arizonans in mind
In addition to providing water to Arizonans within SRP’s service territory, we’re also building water resiliency in municipalities like Goodyear and Payson.
Supplying water to a growing population
Water is our most precious resource. That’s why we’re collaborating on projects to increase water storage capacity for future use, including:
- Working with the Bureau of Reclamation to replace capacity lost to sedimentation in the Verde reservoirs and adding additional storage by raising the height of Bartlett Dam.
- Working with the Army Corps of Engineers at Roosevelt Dam to extend the time water can be stored in flood control allowing the water to be used instead of being spilled down the river.
- Partnering with federal agencies, northern Arizona cities and customers to strategically thin 500,000 acres of forests in northern Arizona by 2035 to protect against catastrophic wildfires
- Working with Central Arizona Project (CAP) on an interconnection project that would allow water stored in SRP reservoirs to be pumped into the CAP canal and delivered to customers outside of SRP’s water service territory.
