(NASDAQ: GWRS), a pure-play water resource management company, today announced that its subsidiaries, Global Water – Santa Cruz Water Company, Inc. (GW-Santa Cruz) and Global Water – Ocotillo Water Company, Inc. (GW-Ocotillo), have recently filed Designation of Assured Water Supply (DAWS) applications with the Arizona Department of Water Resources (ADWR). If approved, the applications would expand the assured water supply in portions of the company’s service areas and support additional anticipated long-term residential and commercial growth. GW-Santa Cruz, the company’s largest water utility, serving one of the fastest-growing areas in Pinal County, Arizona, has an existing assured water supply of 22,914 acre-feet per year from the Maricopa-Stanfield Sub-basin aquifer, which underlies the City of Maricopa just south of Phoenix—one of the largest supplies in the region. This existing assured water supply has provided a strong foundation for growth in and around the City of Maricopa. It is a city of approximately <a href="https://www.globenewswire.com/Tracker?data=zUZpsewzwEXxru-SHiIkfDXDzo60V7BgJB6OR9stDUNlue0ZLrUoxOveSRjiRCkGT8YFj34ger5-FKvx7gk-vGyepeT-baIcaNgBnQBFQx5fkpSx1_uSmO9L7-k6Ik1U2e-NRB-lpmgebIGDy4NUL2o15sY4bgjkGhW4Zwb3t30=" rel="nofollow" target="_blank" title="78,000">78,000</a><a href="https://www.globenewswire.com/Tracker?data=VOt104K-g6LZvMh-lUHJZWxNW45PKTwyn7d3K1DwL3Uuuj2T8YCY9cRgJXBT_DdJ9D7lHfCUFyY39kW6BEZwmBMAFNLClF2eAb1hn6UqwqEo-Ili4BcPJRsUax_vgbRfd5e7fIF03cSmlVjIVgzlyg==" rel="nofollow" target="_blank" title="residents"> residents</a>, up from approximately 1,000 residents at incorporation in 2003. The city used 12,156 acre-feet in 2025, representing just over 50% of GW-Santa Cruz’s existing assured water supply of 22,914 acre-feet per year.          The new DAWS application for GW-Santa Cruz seeks to increase its assured water supply from 22,914 acre-feet to 27,466 acre-feet, or approximately 20% above the current designation. Global Water estimates this would allow for growth in and around the City of Maricopa to approximately 177,000 residents, more than double today’s population. The proposed increase is driven by additional recycled water supplies including from the company’s Southwest Plant and the proposed use of Groundwater Savings Credits under Arizona’s Ag-to-Urban program, which together are intended to broaden the utility’s water resource portfolio and support future development across its northern and southwestern service areas. Arizona’s Ag-to-Urban program is intended to facilitate the transition of agricultural land to urban development while reducing long-term groundwater demand. In January 2026, a developer in GW-Santa Cruz’s service area filed its initial application with ADWR under the new Ag-to-Urban program for the conversion of agricultural land to urban development that allows for the creation of Groundwater Savings Credits. If approved, the proposed credits could be applied as part of the DAWS process to support additional assured water supply, consistent with Arizona’s evolving water policy framework. For GW-Ocotillo, which serves approximately 2,000 water service connections in and around Pima County, Arizona, consisting of seven water systems acquired from the City of Tucson in 2025, the company filed a DAWS application for assured water supply of 1,128 acre-feet. Taken together, the two DAWS applications have the potential to meaningfully expand Global Water’s long-term water resource position in Arizona, and the company believes that the proposed additional assured water supply would support resilient growth for the foreseeable future. Global Water recently reported that active service connections increased 5.7% year over year to 68,885 as of March 31, 2026. The company anticipates decisions on the GW-Santa Cruz and GW-Ocotillo DAWS applications by the fourth quarter of 2027. “The pending DAWS applications for GW-Santa Cruz and GW-Ocotillo reflect the importance of proactive water resource planning in supporting responsible growth across our service territories,” said Ron Fleming, president and CEO of Global Water Resources. “If approved, these designations would further expand our ability to serve residential and commercial development while benefiting customers and the communities we serve through long-term water security, recycled water utilization and regional planning.” The pending GW-Santa Cruz and GW-Ocotillo DAWS applications reflect Global Water’s strategy of pairing disciplined water resource management with community growth in Arizona. The company believes these actions underscore its commitment to supporting customers, developers and municipalities with sustainable water, wastewater and recycled water solutions across its service areas.
