Phoenix Parks To Get Smart Irrigation Upgrades Thanks To $115K Grant

PHOENIX, AZ — Two Phoenix parks are getting smarter irrigation systems thanks to a $115,000 grant from TSMC Arizona, a project city officials say will save thousands of gallons of water while helping keep the parks green year-round.

The grant will fund new Calsense smart irrigation controllers, master valves and flow sensors at Madison Park and Los Olivos Park, allowing the city to better monitor water use, detect leaks and automatically pause irrigation during rainstorms.

With Arizona's monsoon season underway, officials say the upgrades will help eliminate unnecessary watering by shutting off irrigation when rainfall is detected, reducing water waste without requiring staff to manually adjust the system.

The city estimates each skipped irrigation cycle will save about 81,000 gallons of water.

The new technology will also allow parks staff to remotely manage irrigation systems, while built-in flow sensors and master valves can automatically shut off water if a mainline break or other problem is detected, helping prevent significant water loss.

"Water conservation is a top priority for the City of Phoenix and TSMC Arizona, and these investments in our parks illustrate how we can work together to deliver immediate, permanent water savings," Mayor Kate Gallego said. "These smart irrigation controllers at Madison and Los Olivos parks make our green spaces more water efficient."

District 6 Councilmember Kevin Robinson said the improvements will help preserve Los Olivos Park while supporting the city's broader sustainability efforts.

Phoenix officials say the project is part of a larger effort to modernize irrigation infrastructure across the city's parks system and improve long-term water conservation.

TSMC Arizona said the investment also aligns with its own sustainability goals. The company currently recycles about 65% of the water it uses and is working toward a goal of 90%, according to President Rose Castanares.
