The use of fresh water storage tanks is common in rural
areas of Arizona with limited or diminishing water resources.
Homeowners living in remote areas with low-yield and
seasonally dry wells or no wells must depend on water that
is trucked in with tankers and stored on site to cover basic
living necessities. Well owners with low-yielding wells may
also rely on large holding tanks and booster pumps to collect
well water before home delivery with the aid of a pressure
tank. Emergency situations such as fires and water utilities
shortages may also require the short-term storage of fresh
water to cover the basic needs of dispossessed or displaced
persons.
