Expands conservation and resources with the first public-private partnership of this kind in AZ

Goodyear, AZ – Liberty Utilities is partnering with the Central Arizona Groundwater Replenishment District (CAGRD), to build the state’s first ever public-private reclaimed water recharge facility. The CAGRD is the groundwater replenishment authority of the Central Arizona Water Conservation District (CAWCD) commonly known as CAP (Central Arizona Project).
The CAGRD is statutorily obligated to replenish excess groundwater withdrawn by its members in the Phoenix, Pinal, and Tucson Active Management Areas (AMAs). This new recharge facility will replenish the aquifer, reducing the environmental impacts of pumping and helping CAGRD meet its replenishment obligations with a 100 year, renewable water supply. CAWCD is helping to fund the project in exchange for this water supply.
“Liberty is committed to delivering reliable water to our community,” said Greg Sorensen, President of Liberty Utilities – Arizona. “Building this recharge facility with significant funding from the CAWCD allows us to be able to ensure the health of our aquifer, while minimizing the impact to rates of our customers. We are proud to partner with CAWCD to help assure water for future generations.”
CAP Board President Pam Pickard said, "This program provides the CAGRD with a 100 year renewable water supply, which is required in Arizona, known for having one of the toughest groundwater management laws in the country.”
"Also, the replenishment will occur in the area where the pumping is occurring and where the groundwater levels have declined," she said.
Liberty Utilities has twelve different wells which draw from the same groundwater area, or aquifer. As water gets pumped out, the water level falls. To maintain a balance, the aquifer must recharge at the same rate as water is pumped. Reclaimed water is the most reliable, locally-generated supply available for aquifer replenishment.
High quality reclaimed water is commonly recharged into local aquifers and provided for non-potable purposes throughout Arizona and the West. These uses are regulated by the Arizona Department of Environmental Quality and have been proven to be safe. Using reclaimed water in place of potable water also helps preserve our drinking water supplies for the future.
The reclaimed water will come from Liberty Utilities’ Palm Valley Water Reclamation Plant. The plant creates roughly 3.5 million gallons of high quality reclaimed water a day, which is sold for use in irrigation of parks and golf courses. Surplus water will be delivered by special pipes to the recharge facility. These pipes will not be attached to any potable water lines.
At the recharge facility, which has been approved by the City of Goodyear, the water will be pumped into large, shallow basins where it will percolate into the ground ending up in our local aquifer to help restore water levels that have declined due to past pumping.

In 1993, the legislature created a groundwater replenishment authority to be operated by the Central Arizona Water Conservation District (CAWCD) throughout its three-county service area. This replenishment authority of CAWCD is commonly referred to as the Central Arizona Groundwater Replenishment District (CAGRD). The purpose of the CAGRD is to provide a mechanism for landowners and water providers to demonstrate an assured water supply under the Assured Water Supply (AWS) Rules that became effective in 1995.
