Small leaks can waste a lot of water. Phoenix is installing sensors to prevent loss

The City of Phoenix, the Pacific Institute, Target, and Sensor Industries partnered on smart sensor installations at Fillmore Gardens in Phoenix.

Phoenix is looking for every opportunity to conserve water, as it is preparing to face record cuts to its Colorado River supply within the next two years. The city’s smart leak detection program is reminding residents that even small, unseen amounts of water waste can add up.

In partnership with the Pacific Institute, Sensor Industries and Target, Phoenix’s Water Services and Housing departments installed toilet leak detectors in all units at Fillmore Gardens, a public housing community for seniors. A similar installation was done at another senior community, Sunnyslope Manor, three years ago.

According to Phoenix Mayor Kate Gallego, “the program has already saved close to 850,000 gallons of water, reducing the amount of water used at Sunnyslope Manor by nearly 20%. That’s more water than an Olympic-sized swimming pool, all from addressing leaks.”

Max Wilson, the city’s water resource management advisor, says the detectors are an important strategy within a larger effort to protect the city against looming water shortages.

“We’re saddled with a Department of Interior that refuses to lead and headwater states that refuse to try anything above and beyond what they’re doing today,” Wilson said.

“So yes, the Colorado River basin has a problem. But luckily, Phoenix and its partners have a plan and what we’re talking about here today is part of that plan. Developing new and innovative conservation measures to ensure that even the smallest water wastes do not occur in our community. 

City officials hope the program will encourage the public to invest in detectors for their own homes.
