Liberty Utilities to Construct West Valley Water Recharge Facility for CAGRD

11/20/2014

The Central Arizona Groundwater Replenishment District (CAGRD) is partnering with Liberty Utilities to build the state’s first ever public-private reclaimed water recharge facility. The CAGRD replenishes excess groundwater withdrawn by its members in the Phoenix, Pinal County and Tucson areas. This new recharge facility, located in Goodyear, will replenish the aquifer, mitigating the impacts of pumping, and providing CAGRD with a 100-year, renewable water supply to help meet our replenishment obligations. CAWCD is helping to fund the project in exchange for this water supply.

 

Aquifer-card

Liberty Utilities has 12 wells, pumping from the same aquifer that this project will recharge. As water gets pumped out, the water level falls. To maintain a balance, the aquifer must be recharged, or replenished, 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 (A+) reclaimed water a day, which is sold for park and golf course irrigation. 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, 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.

How Wyoming Cloud Seeding Can Benefit the Colorado River

by Mohammed Mahmoud, Planning Analyst

Cloud seeding is the process by which silver iodide is released into the atmosphere using flares from ground-based generators (or aircrafts) to enhance the formation of cloud droplets. The resulting precipitation from winter cloud seeding increases the volume of the snowpack and the subsequent runoff from the snowmelt.
