Liberty’s Sustainable Effluent to Aquifer Project (SEAP) in Litchfield Park, Arizona.

National Protect Your Groundwater Day is recognized on September 5, 2023, to promote the importance of protecting and conserving groundwater. It also serves as a reminder that actions on the surface can impact the groundwater that is treated and eventually delivered to communities and people who then drink it, bathe in it, and clean with it.

Most of the water that Liberty delivers to customers’ homes and businesses is pumped from underground sources called aquifers. The pumps at Liberty’s well sites draw the groundwater to the surface where it is then treated to comply with state and federal water quality standards.

Liberty works to protect and preserve groundwater supplies by investing in sustainable solutions. One way Liberty does so is by helping to recharge local aquifers. In Arizona, A+ quality recycled water from Liberty’s Palm Valley Water Reclamation Facility (PVWRF) is delivered to Liberty’s Sustainable Effluent to Aquifer Project (SEAP), which has a series of basins spanning across 57 acres. The recycled water is then injected into each of the basins and seeps into the ground, which acts as a natural water filter before eventually refilling the aquifer. “What’s unique about this project is we replenish the same aquifer we pull from to supply drinking water to our customers,” said Eric Pena, Operator III at Liberty in Arizona. “This helps to safeguard the drinking water supply for customers now and in the future.” Learn more about how Liberty is helping to protect water supplies on the Liberty website.

Liberty offers other resources to help you gain a better understanding of the importance of protecting groundwater. For example, you can learn how to build a groundwater model with your family to see how groundwater moves, how actions on the surface can impact water supplies, and why conservation is so important. Or, if you want to get involved, read more about the impact human activities can have on groundwater supplies and how you can help protect groundwater. Learn more about groundwater and conservation at
