1. In what ways should OV ensure an available water supply?

CLOSED: This discussion has concluded.
  • Resident Guidance: According to a statistically projectable survey, 68% of OV residents think OV’s biggest challenge will be maintaining the water supply.   
  • Existing Conditions:
    • Oro Valley (OV) has reduced groundwater pumping to historic lows. Since 2005, groundwater pumping has been reduced by over 50%. Groundwater pumping has been offset through Central Arizona Project (CAP) water deliveries and use of reclaimed water for turf irrigation. OV should continue to reduce its reliance on groundwater by increasing the deliveries of other water resources such as CAP and reclaimed water.
    • The Colorado River is over allocated so reductions in its use will be required from all its users. OV has anticipated and planned for a 25% reduction to its CAP water allocation. Approximately 25% of OV’s CAP allocation is not delivered and is stored in nearby underground aquifer storage facilities for future use, if needed. This stored water is referred to as Long Term Storage Credits (LTSC’s). A 25% reduction to OV’s CAP allocation is sustainable but could limit OV’s annexation growth potential without changing how OV manages its water resources.
