Project Overview

The City of Phoenix is securing a resilient and renewable water supply by rehabilitating the Cave Creek Water Reclamation Plant (CCWRP), the first facility of its kind in Arizona to incorporate Advanced Water Purification (AWP). With 98% of Phoenix’s current water coming from vulnerable surface sources like the Colorado, Salt, and Verde Rivers, the city is investing in advanced treatment technology to ensure a dependable local water source.

Sundt is performing significant upgrades to meet future water needs. The project includes retrofitting existing structures and building new facilities to integrate state-of-the-art treatment processes. Improvements include a new coarse screening facility, rehabilitation of the influent pump station, installation of grit removal systems, installation of primary disk filters, conversion of the existing Aeration basin into a Membrane Bioreactor (MBR) basin, and the addition of reverse osmosis (RO) and ultraviolet (UV) advanced oxidation. These upgrades will enhance water quality and prepare the facility for future direct potable reuse (DPR) capabilities.

Supported by Sundt’s self-perform concrete and transportation teams, the construction effort combines precision engineering with large-scale infrastructure work, including new chemical feed and storage systems, odor control upgrades, electrical improvements and instrumentation enhancements.

Once complete, the CCWRP will supply up to eight million gallons of reclaimed water daily, supporting community growth.
