WATER FOR TODAY, WATER FOR TOMORROW
Marana Water Sustainability Outlook
“Town of Marana Water’s Designation of Assured Water Supply from the Arizona Department of Water Resources recognizes that Marana Water can reliably serve up to 7,580-acre-feet per year from our aquifer for over 100 years.
As a Designated Provider, Marana Water is required to maximize the use of renewable supplies and help to attain and maintain the aquifer management goal for Safe-yield.”

Does Marana Water have enough to meet current and future demands?
Current and Committed Water Demands
In 2020, Marana Water used roughly 37% of the supply recognized in its designation to serve current customers. Under the Assured Water Supply program, roughly 26% of the recognized supply is reserved for customers in platted developments. The remaining 37% will serve future customers in developments not yet fully platted.
Does Marana have sufficient groundwater?

The figure to left shows significant water level declines over a period of aquifer overdraft from 1940 to the turn of the century. The figure at right shows how, since the turn of the century, water providers have reversed this decline by importing CAP water, recycling water, conserving water, and/or replenishing groundwater. Together, the figures show the importance of sound management of our aquifer and water resources.
Marana Water actively partners with other local water providers, stakeholders, and local and federal agencies to ensure the sound management of our water resources. For more information, visit the 'LEARN MORE' links below.
What does the colorado river shortage mean for Marana?
In 2022, the first-ever Tier 1 shortage will reduce the available water supply for the Central Arizona Project (CAP) by about 30%. This level of shortage will impact agricultural water users; water supplies for cities and towns will not be affected. Marana Water’s CAP water supply will not be reduced by this Tier 1 shortage.
