Water, Wells & Septic in Cave Creek
Water is the make-or-break item in Cave Creek residential property due diligence. The area uses multiple water sources and many properties rely on private wells and on-site septic. Understanding the water picture on any specific parcel before you close is not optional.
Water Sources
The Town of Cave Creek's water system is served by Central Arizona Project (CAP) water. The Desert Hills water system relies on groundwater wells supplemented with CAP water. Many residents in the broader area use private wells entirely. Confirm the water source and provider for any specific parcel from the Town or County before assuming anything. For a private well, confirm permit status, depth, yield, and allowed uses with the Arizona Department of Water Resources. A new well requires a Notice of Intent to Drill before drilling.
Well Due Diligence
A well inspection for a residential property requires a 6-hour sustained pump test — not the 4-hour minimum sometimes accepted in residential transactions. What matters for an equestrian operation is GPM under sustained draw and recovery rate after pumping stops, not just whether the well produced water during a short test. A conservative daily water estimate for four horses, dust control, and a maintained arena in an Arizona summer runs 100 to 150 gallons. The Arizona Department of Health Services recommends testing private wells for arsenic, coliform bacteria, fluoride, lead, nitrates, TDS, and uranium — arsenic is a documented concern in parts of Maricopa County groundwater. A seller who cannot produce a recent pump test and water quality report should be treated as a property where neither exists.

Sewer is not available everywhere in Cave Creek. Properties on acreage typically use on-site septic. In Maricopa County, a septic system must be inspected within six months before ownership transfer, and the buyer must file a Notice of Transfer within 15 calendar days after closing. Evaluate septic capacity against the planned number of occupants and any accessory dwelling before you close.
