Underground Storage Facilities

Purpose and intended use - This data set is used for analysis by the ADWR Recharge and Recovery group and is displayed in several ADWR GIS applications. Description of USF Program: An Underground Storage Facility (USF) Permit(A.R.S. § 45-811.01) allows the permit holder to operate a facility that stores water in the aquifer. The criteria a USF must meet in order to be permitted include:1. The project must be hydrologically feasible;2. The applicant must demonstrate financial and technical capability;3. The applicant must agree in writing to obtain any required floodplain use permit from the county flood control district before beginning any construction activities;4. The project may not cause unreasonable harm to land or other water users within the area of impact; and5. The project will continue to be monitored to ensure storage does not cause the migration of poor quality water. 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. All surface flows entering and exiting a managed underground storage facility must be measured at the facility boundaries in a manner consistent with the Department’s measuring device rules (R12-15-905 & 906 ). Data creation methodologies, processing, and quality - Locations have been determined using aerial imagery, handheld GPS equipment, or materials supplied by permittees. Underground Storage Facility (71- ) feature class was dissolved over the rechargeUSF feature class and is maintained by ADWR. Each shape was created to reflect the permitted recharge boundaries of basins, wells, and river channels. This is a dissolved version of the LIB.rechargeUSF dataset and is displayed in multiple applications. Data limitations – ADWR staff have worked to improve the accuracy of features within this dataset , however ADWR makes no claims regarding the data quality. For instance, the dataset may not capture all current features of facilities or permits. Please refer to ADWR Data Disclaimer. Currency – This data is updated as new Underground Storage Facilities are permitted/inspected or when inaccuracies come to attention of the Recharge team. Last Updated September 2024. Contact– Hydrogeologist, Planning and Permitting Division, Recharge and Recovery Section, (602)771-8737 [https://www.azwater.gov/form/recharge-contact-form] Attribute information - Program: Number associated with the USF program. This is 71 for USFs. Certificate: 6 digit number which follows “71-” and identifies each underground storage facility Conveyance: 4 digit number identifying a permit’s conveyance number. This typically increases by one whenever a permit modification or renewal is issued for the facility. This number follows the Program and Certificate which when combined follows a format of: 71-xxxxxx.xxxx. Phase: listed if a component is associated with a particular phase in the USF permit Status: Active if currently able to use for recharge. Inactive if not. Map_Label: Name for display on map. Shortened from “Name” Water_Type: Water type that facility is permitted to store, (i.e. CAP, effluent, etc.) Permitted_Volume: Maximum permitted volume for the entire USF. This does not include any phased volumes.
