Tucson Water's Drought Preparedness and Response Plan includes specific indicators and actions the utility and its customers can take based upon:
- The level of drought response needed.
- Our use of both groundwater and Colorado River water.
- The attributes of our water system.
- How our customers actually use water.
Tucson Water's plan includes four drought response stages. Once Stage 1 has been declared for Tucson Water's service area, progression through Stages 2, 3, and 4 will be declared based on threats to Tucson Water's Colorado River supplies and/or local system indicators that may have negative impacts on the utility's groundwater supplies.
- Stage 1 — Declared based on regional indicators such as a severe and sustained drought on the Colorado River and/or a State of Arizona declaration of drought in the Tucson region.
- Stage 2 — Declared if an initial shortage (i.e., a shortage that does not affect municipal uses) is declared on the Colorado River, or if local system factors require additional response actions.
- Stage 3 — Declared based on limited reductions in Central Arizona Project (CAP) deliveries to the City of Tucson or if local system factors require additional response actions.
- Stage 4 — Declared based on additional reductions in CAP deliveries to the City o Tucson or if local system factors require additional response actions.
