The Transmission and Distribution Section (water infrastructure) consists of more than 500 miles of transmission/distribution pipe, over 18,000 valves, more than 3,600 fire hydrants, and some 34,000 water meters. There are two pressure zones within our system.

Transmission-Distribution Section

The transmission/distribution lines (pipes) range from 2 inches to 48 inches in diameter. Pipes are made from various materials such as concrete, steel, PVC, or other material.  The age of the pipes and valves are from 60+ years old, to newly installed.
 
 Due to the age of the majority of our infrastructure, leaks and breaks do occur. Our employees are on call twenty-four hours a day to repair line breaks or leaks.

If you see a leak in the street, alley or parkway,
call (928) 373-4600.

If it's AFTER hours, call (928) 783-7601.

This section maintains a valve exercise program, a hydrant maintenance program, a water quality flushing program, and also flushes lines due to water complaints and/or during construction projects. They install new water services and water meters, and perform Blue Stake locate requests in a timely manner.

 All water distribution system technicians are qualified and certified operators as required by the Arizona Department of Environmental Quality. These technicians must complete continuous educational and safety trainings to maintain their certifications and enhance their professional development.

Flushing

Why We Flush

Fresh drinking water is one of our most valuable and perishable commodities. Flushing improves the water quality that is delivered to our customers by moving fresh water into areas that suffer from low water demand. One of the main variables that reduce water quality is time (water age) and dead end water mains. There are over 450 dead ends in our water distribution system. Most of these dead ends are results of cul-de-sacs, undeveloped subdivisions, water pressure zones, and expansions for future growth.

 A New Way of Thinking

20 years ago, Water Systems Designers and Engineers thought the more water storage available, the better. That statement still has some truth to it today if you're only thinking of emergency conditions. It was also believed that once water entered the distribution system, the water quality would remain the same. Today's way of thinking is to have the capacity to produce and deliver the water quickly, while maintaining enough water for emergencies. The Environment Protection Agency (EPA) conducts research and implements new regulations to help us keep our water safe. The Utilities Department has been diligently working on optimization of its water treatment process and water distribution system to deliver high quality water that meets or exceeds all regulatory requirements.
