Where can I get water?
Arizona water, in three numbers
of Arizona's 1,490 active public water systems have an unresolved drinking-water violation on record.

official statewide lists of water haulers. No Arizona agency publishes one, which is the reason this site exists.
Hauling is permitted county by county (A.A.C. R18-4-125); those permit lists are not published online.
What to do
My water is out right now
- Search your address above and call the haulers listed. Ask about emergency or same-day delivery, and confirm they serve your road, not just your town.
- Standpipes usually are not walk-up. EPCOR's Rio Verde Foothills station needs an account and a PIN before you can draw water, so signing up is step one, not step two.
- If you cannot reach anyone, call your county emergency management office. They coordinate water assistance during outages and can point to bulk distribution if it exists.
- For drinking in the meantime, bottled water from any store is safe. Do not drink from a well or a tank you suspect is contaminated.
I rely on hauled water
- Know your tank size and roughly how many days it lasts. Order before you are near empty, since haulers schedule days ahead and demand spikes in summer.
- Ask any hauler whether they carry potable water specifically. Construction water and dust-control water are hauled by the same kind of truck and are not for drinking.
- Ask where they source from. A hauler drawing from a permitted public system is drawing water that gets tested.
- Keep a second hauler's number. Single-supplier dependence is exactly what went wrong in Rio Verde Foothills in 2023.
I have a private well
- Nobody tests your well for you. Private wells are outside EPA and ADEQ drinking-water rules, so testing is on the owner.
- Test at least annually for bacteria and nitrate, and in Arizona also consider arsenic, fluoride and uranium, which occur naturally in some aquifers here. Use an ADHS-licensed lab.
- Look up your well in ADWR's registry to confirm depth and construction details before you assume anything about it.
- If the water level is dropping, note it. Regional decline shows up in the well and subsidence data this site reports as background context.
I'm buying property without a water connection
- Search the address here first. If no provider serves it, no utility is obligated to bring water to that lot, ever.
- Ask specifically whether the parcel has a 100-year assured water supply determination. Lots split without one are how Rio Verde Foothills happened.
- Get the well's actual production rate in writing, not the seller's description of it.
- Price hauled water into your monthly costs before you buy, not after.
My tap water looks, smells or tastes wrong
- If you have a provider, look up its record above, then request its Consumer Confidence Report. Every community water system must give you one and it lists what was detected.
- Report the problem to your provider first and write down when you reported it.
- If they do not respond, ADEQ's Safe Drinking Water Program takes complaints about public water systems.
- Discoloured water after main work is usually sediment. Persistent taste, smell or illness is worth escalating rather than waiting out.
