Water Stewardship
● Project Blue will not deplete any Tucson Water resources available to the City today, and will therefore not result in deductions to Tucson Waters current assured Water Supply portfolio. Since Project Blue is replenishing all water losses and will be providing water in excess of consumption, it will be a Water Positive customer. Water positivity will be achieved through two correlating mechanisms which in sum are Water Positive:○ Tucson Water will charge a rate for all water used at the Project to include the Tucson Water cost to increase Tucsons water portfolio; and○ Project Blue will fund local water projects within the region or bring new water supplies to the region to augment and supplement Tucsons replenishment efforts.
● This commitment towards water positivity is a contractual obligation, outlined specifically in the Development Agreement with the City. All potable water consumed will also be replenished via the Water Positivity requirements in the Development Agreement. The Development Agreement also includes punitive language that does not allow for long term use of potable water for industrial purposes.
● Selected projects need to be located within watersheds that connect to Tucson Waters supply portfolio, must demonstrate measurable benefits to water quality, quantity, or availability and contribute to Tucson Waters Assured Water Supply as regulated by ADWR.
● Potential projects may include bringing additional water supply and long-term storage credits into the basin, supporting potable reuse through funding advanced treatment technologies or public education; implementing PFAS removal treatment at wellheads or treatment plants; restoring rivers and wetlands to enhance infiltration; developing green stormwater capture infrastructure; or advancing water conservation through initiatives like Advanced Metering Infrastructure for early leak detection or funding efficient toilet replacement programs.
● Project Blue has aligned its approach to water stewardship with Guiding Principles from Tucson Waters One Water2100 Plan, including delivering reliability, reinforcing resiliency, enhancing the communitys quality of life and achieving accessibility.
