Construction is now about halfway complete on the Phoenix’s first advanced water purification plant, a $300 million project designed to convert wastewater into high-quality drinking water. The facility is part of the city’s Pure Water Phoenix program, an initiative aimed at expanding Phoenix’s use of highly treated recycled water as drought, population growth, and pressure on traditional water sources continue to reshape water planning across the region.

The advanced purification plant is expected to become more important over the next decade as Phoenix works to diversify its water portfolio and reduce dependence on more vulnerable supplies.

Workers at the Cave Creek Water Reclamation Plant filled one of the new treatment basins with 1 million gallons of water, a symbolic step underscoring the scale of the project and its role in the city’s future water supply.

Construction on the facility began in 2024 and is expected to be fully operational by 2029. It’s expected tp have enough to serve an estimated 25,000 to 30,000 homes.
