Abstract: Tucson’s One Water Future

Tucson’s mayor and council adopted the One Water 2100 Master Plan on October 17, 2023, with a goal of ensuring a sustainable, high quality water supply into the future. The plan’s outlook spans the next 77 years, bringing us to year 2100. It outlines a One Water approach, which values the interconnectedness of all water: surface water, groundwater, recycled water, and rain and stormwater harvesting. Long-range water resource management through 2100 is accomplished through 16 strategies and 68 implementation actions defined in the plan, which aim to protect the reliability and quality of Tucson’s water supply under changing conditions. Although the plan was just recently approved, we have made substantial progress implementing several strategies for the benefit of Tucson and the region. This talk will focus on the implementation of the plan in its first year (2023) and highlight noteworthy actions that have already been completed. The City of Tucson and Tucson Water are proud of the progress that has taken shape over the past year, and we are excited to share this progress update with the AHS community.
