No public water provider for Watkins was verified in our research, and some Watkins-addressed properties are actually inside Aurora, so backflow rules depend on your exact address and supplier. Check your water bill or the county, and for help with a device, call the number on this page to be connected with a local plumber in Watkins.

Who supplies water in Watkins?
It varies, and the fact sheet couldn't confirm a public provider. Watkins is a rural community with dry-farming and ranching roots, the westernmost community on the eastern I-70 corridor, right on Aurora's border. Adams County's list of water and sanitation districts includes none with a Watkins address, and the county's Water Master Plan says eastern Adams County relies mainly on Denver Basin groundwater, including rural residents who supply their own water from wells. The Watkins post office itself sits inside Aurora city limits, so some Watkins addresses may be in Aurora and on Aurora Water.
What backflow rules apply to me?
If your address is in Aurora and Aurora Water bills you, Aurora Water's cross-connection rules apply, including annual testing of any required assembly. If a district or HOA water system serves you, ask it. If your home has its own well, no utility tracks your devices, but protecting connections still keeps your well clean. The newer neighborhood of nearly 100 homes and the farms around it may fall in different categories, so check your own bill.
Where do I get a permit?
Watkins is unincorporated and split between Adams and Arapahoe counties. On the Adams County side, the One Stop Permitting Center (720.523.6800) requires permits for plumbing modifications. On the Arapahoe side, the county's Building Division in Centennial handles permits. If your property is inside Aurora, the city's Building Division does.
When you call, tell the plumber which county you're in and who, if anyone, bills you for water. That decides where a test report goes, if one is needed. If you're on Aurora Water, the tester should hold an ASSE or ABPA backflow certification, which Aurora requires.
Local note
With a median build year of 2002, much of Watkins' housing is fairly new, but rural connections like hydrants, tank fills and sprayer lines are common. A vacuum breaker on each spigot and an air gap on tank fills go a long way. Drain outdoor devices before the plains freeze, and check them in spring before turning water back on to lawns and tanks.
