Aquatic weeds and water delivery are typically not a good combination. When weeds are growing in CAP’s 336-mile closed system, they tend to slow water flow by causing excess friction. When the vegetation dies, it floats to the surface and eventually restricts water flow to the pumps by clogging the trash racks. If our rake systems can’t keep up, the pumps will shut down due to vibration, cavitation, or just a lack of water. In many water conveyance systems, drying out the canal or using a good dose of aquatic herbicide is used to control or eliminate weed growth. However, CAP delivers water to municipal and agricultural customers 365 days a year, so drying out the canal isn’t possible and chemical treatment can’t be used. So at CAP, we invite a special guest to the salad bar!

Safety is a daily priority in every job at CAP, and last week that commitment was renewed at CAP’s seventh annual Safety Week.  

Employees attend classes at CAP’s Headquarters that focused on making employees’ daily lives safer, whether they are at work or at home. Various safety-related topics were covered such as confined spaces, first aid, snake handling and more.

We live in the desert, but we keep an eye on the snow in the Rocky Mountains.  That’s because CAP’s source of water is the Colorado River and more than 90 percent of the river’s flow originates as snow in the Rocky Mountains of Colorado, Wyoming and Utah.

Earth fissures in Arizona aren’t new, but recently a two-mile long fissure in Pinal County made the news, bringing to light one of the consequences of extensive groundwater pumping. Fissures like this can pose a risk to homes, buildings, roads and even the Central Arizona Project (CAP) system.
