Our story

At SRP, we believe in building a better Arizona one innovative step at a time.

    Delivering reliable and affordable water and power since 1903

    Salt River Project, or SRP, is a community-based, not-for-profit organization providing affordable water and power to more than 2 million people in central Arizona.  

    It’s made up of two separate organizations: the “Association,” a private water corporation founded in 1903, and the “District,” an electricity provider formed as an agricultural improvement district and a political subdivision of the State of Arizona in 1937.  
    By providing these essential resources for more than a century, we’ve helped the Phoenix metropolitan area develop and thrive. 

    Our guiding principles have remained the same since our founding – to act in the best interest of the people we serve and strive to help build a better future for Arizona. See how decisions get made.

    It all started with ranchers, farmers and a massive dam 

    Theodore Roosevelt Dam, to be exact. The ranchers and farmers who lived in the area pledged their own land to get the dam built as a way to tame the raging waters of the Salt River. They formed the Salt River Valley Water Users’ Association, the founding group of SRP. Explore more SRP history.

    Our mission is to build a sustainable future in the Valley

    We make decisions through the eyes of future generations, balancing costs and impacts while providing reliable, sustainable water and power — for today and tomorrow. 

    We’re holding ourselves to this with an ambitious set of goals that center on:

    • Reducing our carbon footprint
    • Ensuring water resiliency
    • Meeting customer needs through a modern, resilient energy grid
    • Promoting a sustainable supply chain and reducing waste
    • Engaging with our communities 

    We strive to reflect the communities in which we live and work

    Diversity helps make our communities and businesses stronger – that's why we put it at the heart of everything we do. We’re committed to diversity, equity, inclusion and belonging, and we carry these values into our workplace, our focus on customer needs, and our community investments.  

    In our communities

    We support diversity in the communities we serve through volunteering, financial contributions and educational programs that address underserved needs.

    In our suppliers

    We’re committed to supporting a broad coalition of diverse business partners, including woman-, minority- and veteran-owned businesses.

    In our workforce

    We provide equal employment opportunities in order to gain unique perspectives and solutions that best serve our customers.
