TUCSON WATER PREPARES
FOR TEMPORARY CONVERSION TO GROUNDWATER SYSTEM
Tucson Water is preparing to temporarily convert to groundwater wells to provide water service to customers. The conversion will take place starting Monday, September 13 and is scheduled to continue until Friday, October 29. The change in water sources is a result of a scheduled maintenance shutdown of the Central Arizona Project system.
Tucson Water uses renewable water supplies from the Colorado River to meet customer demands. The water is delivered using infrastructure operated by the Central Arizona Project (CAP). The CAP annually shuts down portions of its system as part of its maintenance program.
The temporary shutdown of the CAP system will not affect the ability of Tucson Water to deliver water. While the main transmission pipeline that delivers most of the water into the community will be taken out of service during this period, Tucson Water operates several well fields that are independent of CAP infrastructure.
To prepare for the transition to groundwater wells, Tucson Water crews have been flushing inactive wells to clear any sediments, such as silt and sand particles, that may have accumulated while they were out of service. Some areas within the distribution pipe network may also be flushed at fire hydrants, as sediments can accumulate in pipes over time.
Tucson Water customers should not experience interruptions in water service. However, it is possible that customers might experience sediments flushing through their pipes, or air bubbles, giving the water a white, cloudy appearance. It should be noted that either sediments or entrained air bubbles in water do not present a health risk.
While measures are being taken to avoid these types of problems, customers are advised to flush their water lines at a spigot closest to their water meter if they detect dirty or cloudy water. If the problem persists, customers are asked to contact Tucson Water’s Water Quality Customer Support Unit at (520) 791-5945 during normal business hours, or at the emergency line at (520) 791-4133 all other times.
