The upside a well gives you
A park serving its own water avoids a purchased-water bill that, in some Arizona submarkets, is one of the larger line items on the P&L. During peak season that difference can be substantial. Owners frequently undersell this — if your water expense is low because you produce your own, say so and show the electricity cost of pumping alongside it so the comparison is honest.
What buyers actually want to know
- Capacity versus peak demand. Can the well and storage carry the park at full winter occupancy, with irrigation and a pool if you have one? Peak-season demand, not average demand, is the test.
- Depth, age and yield. When was it drilled, what does the log say, and has yield changed over the years you've owned it?
- Pump and controls. Age, horsepower, whether there is a spare, and what happens operationally the day the pump fails in February.
- Storage and pressure. Tank capacity, booster systems, and whether sites at the far end of the loop hold pressure when the park is full.
- Water quality and treatment. Any chlorination, filtration or softening, and the results of recent testing.
- Compliance status. Whether the system is treated as a public water system because of the population it serves, and what sampling, reporting or operator certification obligations come with that.
- Distribution lines. Material, age, known leaks, and whether the metered production reconciles roughly with expected usage.
- Backup. Is there a second well, a connection to a municipal or private provider, or nothing?
Where to verify Arizona requirements
Requirements depend on your well, your service population and your location, and they change. Do not rely on a website — including this one — for your park's specific obligations. Well registration, drilling and water rights matters run through the Arizona Department of Water Resources. Drinking water quality, monitoring and public water system rules run through the Arizona Department of Environmental Quality. Your county environmental health department may have additional requirements. Confirm your status with those agencies and your own professionals.
What buyers do with problems
Well problems get priced, not avoided — provided they are disclosed and understood. A park with a tired pump, aging galvanized lines and no recent testing will absolutely still be bought; the buyer simply reserves capital for the work. What kills deals is a seller who knows the far loop loses pressure every January and says nothing until the buyer's inspector finds it in week three of due diligence.
Before you spend money
Redrilling, replacing distribution mains or building new storage are large expenditures with uncertain return at sale. Get a read on what the park is worth as-is, with the well as it stands, before you commit that capital. If the work genuinely lifts value more than it costs, that will be visible in the conversation.
