Identify every claimed water source
Begin with a plain inventory. Is the house served by a water company, a private well, a shared well, hauled water, or more than one source? Which source serves the home, troughs, irrigation, arena watering, and outbuildings? Record the answer as a seller statement until documents and providers support it.
For a well, request the registration number, well log or report, maintenance records, pump information, invoices, testing, and any sharing agreement. Match the reported location and identifiers across the parcel record, ADWR record, title material, and field visit. A mismatch belongs on the open question list.
Read the ADWR warning with the data
ADWR's Well Registry can show registration, owner and driller supplied information, associated rights, and pumping data where available. ADWR also states that registry data is not independently verified. That limit belongs beside every registry finding, not in fine print after a conclusion.
A reported depth, water level, pump capacity, or historical test does not establish current output, reliability, legal rights, water quality, or future supply. Ask ADWR or a qualified water professional to explain classifications and records. Ask qualified counsel about legal rights. Ask a licensed or otherwise qualified contractor to evaluate the current equipment and performance.
- Official record: ADWR registration and available reported well data.
- Seller statement: source, sharing arrangement, service history, and typical operation.
- Field observation: visible equipment, tanks, meters, lines, troughs, leaks, and access.
- Unverified question: current flow, recovery, quality, condition, capacity, rights, and future reliability.
Test the plan, not just the tap
Tell the contractor and laboratory how the property may be used. Household demand and animal demand are not the same question. Arena watering, irrigation, storage, seasonal use, and fire protection questions may change the plan. A buyer selected professional should explain test conditions and what the result does not predict.
Water quality requires a buyer selected laboratory panel and qualified interpretation. Treatment equipment needs a separate condition and maintenance review. No single reading proves that water is sufficient, safe, potable, suitable for animals, or reliable over time.
Keep septic in its own system file
Pima County regulates onsite wastewater systems and publishes a transfer inspection process. The County says the person transferring a property served by an onsite system must retain a qualified inspector within six months before transfer, provide the report and documents to the buyer, and follow the applicable filing steps.
Request available permits, design and maintenance records, the current inspection report, and the seller's documents. Ask the qualified septic professional about system type, location, observed condition, capacity questions, maintenance, and recommended work. A septic transfer report is not a horse facility review, and a real estate agent does not certify either system.
Test a well record is a starting point. it is not a water answer. against the actual parcel.
A listing label is not proof. Pair the record with field observation and qualified review.
