Sarival Water Reclamation Facility - Residential - Arizona Water - Liberty

When operational in 2024, Liberty’s Sarival Water Reclamation Facility (“Sarival WRF”) will be able to treat 4 million gallons per day (MGD), bringing the total wastewater treatment capacity for Liberty – Litchfield Park to 10.55 MGD. This will allow Liberty to better meet the demands and needs of our growing Goodyear and Litchfield Park communities.

The Sarival WRF will also help support Liberty’s sustainability initiatives by producing Class A+ quality effluent, the highest level of reclaimed water, which can replace potable water for activities such as park or landscape irrigation, artificial lakes or other water features, and more.

The reclaimed water treated by the Sarival WRF will also be recharged back into the local groundwater aquifer at our Sustainable Effluent to Aquifer Project (SEAP). This will help replenish groundwater levels and supplement our water supplies, supporting our customers’ potable water needs and helping our communities to be more resilient during times of drought.

As our communities continue to develop and grow, our new water reclamation facility will help Liberty to continue to provide safe, reliable wastewater service to our customers, and uphold our commitment to environmental stewardship.

McDowell Force Main Project Progress

The McDowell force main project is vital to continue providing safe and reliable wastewater service to our customers while also upholding our commitment to environmental sustainability. This project enhances our ability to address the evolving needs and demands of our expanding communities in Goodyear and Litchfield Park.

Crews will be installing a new 18-inch water reclamation pipeline along McDowell Road from the Sarival Avenue intersection to the N. Bullard Avenue intersection. Once the new Sarival WRF is complete, this pipeline will be used as the effluent line to convey re-use water to the SEAP and re-use locations.
