Drought is defined as an extended period of below normal precipitation on a watershed. Cycles of drought and surplus conditions in regional water supplies are a normal occurrence.
Surprise receives drinking, agricultural, and landscape water from three sources: groundwater, reclaimed water, and Colorado River water (surface water from the Central Arizona Project). Currently, Surprise relies solely on groundwater for drinking water purposes. Reclaimed water is used primarily for agricultural and landscape irrigation; some surface water from the Colorado River is also used for irrigation purposes.
Surprise has a diverse water portfolio including groundwater, Colorado River water, and reclaimed water, and has obtained water credits through water recharge.
The Colorado River is Arizona's largest source of surface water, and the Central Arizona Project (CAP) canal delivers just over half (about 1.5 million acre-feet) of Arizona's allocation to central and southern Arizona. Surprise’s annual CAP allocation is 10,249 acre-feet.
The City’s water conservation program provides resources, workshops, and rebates to educate and promote the efficient use of water across all sectors in the community including residential, commercial, HOA, and industrial uses.
