Avra Riparian Restoration and Groundwater Replenishment

The Pima County Avra Valley Wastewater Treatment Facility (AVWWTF) site, located near Snyder Hill and Sandario Roads, currently produces 1.2 million gallons per day (mgd) of wastewater.  Most of the effluent produced is released into several percolation ponds.  Please see the Avra Riparian Restoration and Groundwater Replenishment Project report for more information.
