Salt River Project Utility Locating

Cardno’s long-term partnership with the Salt River Project Authority is contributing to the safe and stable delivery of power and water to metropolitan Phoenix.

The Salt River Project has delivered power and water to metropolitan Phoenix for more than a century. It consists of two separate entities: the public Salt River Project Agricultural Improvement and Power District, and the privately-held Salt River Valley Water Users’ Association. 

The Salt River Project Agricultural Improvement and Power District provides electricity to more than 900,000 retail customers in the Phoenix area. It participates in the operation of, 11 major power plants as well as other forms of power generation including thermal, nuclear, gas, and hydroelectric.

The Salt River Valley Water Users’ Association delivers nearly 1 million acre-feet of water per year to central Arizona, via an extensive water delivery system consisting of reservoirs, canals, wells and irrigation laterals. 

Cardno was commissioned in 2000 to provide specialized utility locating and designating – preparing 25-30 utility test holes and 7,000 linear feet of designating daily.  

Working as the Salt River Project Authority’s valued partner through their modernization process, Cardno is also assisting with the removal of overhead power lines and relocating them underground as well as replacing old electric cables with new cable.  

To facilitate this work, Cardno first designates the areas so Salt River Project crews can easily identify the new trench route. Any utility conflicts crossing the new trench routes are located using our fleet of vacuum excavation trucks.
