Places to get water
Our own directory, compiled from public records and research
Standpipes, refill stations and water haulers. No Arizona agency
publishes a statewide list of these, which is the gap this site
exists to fill. Entries come from company records, utility
announcements, news coverage and local knowledge, and each one shows
where its details came from and when.
Limits: businesses close, phone numbers change and
service areas shift. Distances are measured from a company's
registered address, not from the edge of where it will actually
drive, so a hauler further away may still deliver to you and a close
one may not. Call before you count on any listing, as with any
directory.
Water haulers
Federal Motor Carrier Safety Administration (FMCSA) census
Arizona licenses potable water hauling county by county
(A.A.C. R18-4-125), and those permit lists are not published online.
Haulers do drive trucks, though, and trucks are registered federally,
so we search the FMCSA carrier census for Arizona carriers whose
business names indicate water hauling: 74 companies across 36 cities.
Limits: matching on names is imperfect in both
directions. A hauler named something like "Sunrise Transport" won't
be found, and lookalikes have to be excluded by hand: "Winston Water
Cooler" is a plumbing supplier, "Buckeye Water Conservation &
Drainage District" is an irrigation district. Companies listed may
haul only construction or dust-control water rather than potable.
Public water points
OpenStreetMap, ODbL
962 mapped drinking-water points across Arizona, contributed by
volunteers. These fill the gap outside the communities the directory
covers in detail, so that a search anywhere in the state returns
something.
Limits: most are drinking fountains, park taps and
campground spigots. They are useful for filling bottles or a jug and
are not a way to fill a household storage tank. They
are also unverified by us, and a volunteer-mapped tap may have been
removed years ago.
Your water provider
ADWR Community Water System service areas
The official boundaries of Arizona's community water systems, used to
answer who serves a given address: 846 mapped service areas. Each
carries an ADEQ ID, which is the same identifier the EPA calls a
PWSID, and that is what links your provider to its federal compliance
record.
Limits: 113 systems in the source data have no
mapped boundary at all, so they can never match an address and are
excluded. A provider may also serve customers slightly outside its
mapped area. If the site says no provider serves you but you receive
a water bill, believe the bill. For much of rural Arizona, though,
"no provider" is the true and important answer: no utility is
obligated to bring water to that parcel.
Safety violations
EPA Safe Drinking Water Information System, via ECHO
Federal drinking-water compliance records for every active Arizona
public water system, refreshed quarterly. Health-based violations are
reported separately from total violations, violations that are still
unresolved are counted on their own, and anything since 2021 is
flagged as recent.
Limits: a violation is not automatically a health
emergency. Many are monitoring or reporting failures, meaning a
system did not test or file on time rather than that anything was
found in the water. Records also run back decades, which is why raw
totals are shown alongside recency rather than on their own. No
violations on record does not guarantee your water is safe today.
Private wells are not covered at all: they fall outside EPA and ADEQ
drinking-water rules, so nobody tests them but you.
Wells
ADWR Wells55 registry, combined with the GWSI monitoring index
Wells55 is Arizona's well registration database: every well drilled
in the state must be registered, including exempt domestic wells.
That is roughly 218,000 records. GWSI, the Groundwater Site
Inventory, is a much smaller network of about 46,800 sites where
water levels are physically measured. The two are combined, treating
points within 60 metres of each other as one well, for about 257,000
in total.
Limits: GWSI on its own is a monitoring sample, not
a census, and undercounts real wells roughly ninefold, which is why
it is not used alone. GWSI also includes springs and sites predating
the 1980 registry, so not every point is a registered well. Depths
and drill years are recorded inconsistently and are often blank. The
Wells55 data reaches us through a public mirror published by the
Arizona Association of Conservation Districts rather than directly
from ADWR, so its refresh date is not something we can confirm.
Regulatory context
ADWR AMA/INA boundaries and Assured Water Supply determinations
Active Management Areas and Irrigation Non-Expansion Areas are the
parts of Arizona with real groundwater regulation: all 11 are
included. Assured and Adequate Water Supply determinations record
where a subdivision had to prove a 100-year water supply before it
could be approved: 5,594 of them.
Limits: this is background, not a verdict on your
water. Being inside an AMA does not mean your supply is secure, and
being outside one does not mean it is not. Rio Verde Foothills sits
inside the Phoenix AMA and still lost its water access in
2023, because the problem there was the absence of a provider and of
supply determinations on split lots, not the AMA boundary.
Turning an address into a location
U.S. Census Bureau geocoder, with Photon for suggestions
Addresses are matched by the Census Bureau's public geocoder, which
knows US address ranges. Type-ahead suggestions come from Photon,
which is built on OpenStreetMap. All of it runs in your browser: your
address is never sent to us and nothing is stored.
Limits: the Census geocoder does not know every
rural address, and rural addresses are much of the point of this
site. When it cannot find one, the site falls back to the coordinates
of the suggestion you picked and labels the result as approximate.
