•Was not included in the most recent Land Use Assumption (LUA)
nor the DAWS projection.
•Adjacent system has no excess Storage or Booster Station
Capacity, therefore:
Storage needs to be 150% of ADD plus fire-flow –need at least
262,000 gallons of storage.
Well would need to meet PDD: recommend 250 gpm minimum.
Booster station must meet PDD + fire-flow. Will require hydraulic
modeling to determine actual size of required booster.

Water Reclamation Services
•Saguaro Bloom Lift Station –No remaining
capacity.
•Sewer Lines –No remaining capacity after
Mandarina is developed
•Water Reclamation Facility (WRF) –No
sufficient treatment capacity. Will need to
build additional treatment capacity in the
existing WRF.
•It is costly to construct another force-main
crossing Santa Cruz River.
•Potential opportunity to work towards a brand
new WRF and a recharge facility west of Santa
Cruz River.
