Implementation of an Integrated Membrane System to Expand Reuse – City of Phoenix Cave Creek Water Reclamation Plant

The Cave Creek Water Reclamation Plant (CCWRP) is one of three wastewater treatment facilities either owned or co-owned by the City of Phoenix (City). The 8 mgd facility was placed in operation in 2002 but was taken offline in 2009 due to slower than anticipated growth in the surrounding area. Due to resumed growth, the City authorized Black & Veatch (B&V) to conduct a Phase I Feasibility Study (completed in 2017) to identify any existing design limitations and evaluate alternatives to improve overall process performance and reduce operational costs. Phase II CCWRP improvements include the design/equipment procurement of membrane systems (MBR and RO) to expand the plants reuse production capacity and improve reclaimed water quality.
