A Constructed Underground Storage Facility Permit allows for water to be stored in an aquifer by using some type of constructed device, such as an injection well or percolation basin. A Managed Underground Storage Facility Permit allows for water to be discharged to a naturally water-transmissive area such as a streambed that allows the water to percolate into the aquifer without the assistance of a constructed device.  Information regarding the criteria a facility must meet in order to be permitted as a USF is included in A.R.S.  § 45-811.01
