In the desert Southwest, water rights can make or break a property investment. Understand what you're buying before you sign.
Water is precious in Arizona, and understanding water rights is essential for any property purchase, especially outside municipal water systems.
## Types of Water Rights
### Surface Water Rights Rights to use water from rivers, streams, and lakes. In Arizona, these are largely adjudicated and can be very valuable.
### Groundwater Rights Arizona has three groundwater management systems: - Active Management Areas (AMAs): Most regulated - Irrigation Non-Expansion Areas (INAs): Moderate regulation - Remainder of state: Relatively unrestricted
## AMAs Explained
Active Management Areas include Phoenix, Tucson, and other high-growth regions. Within AMAs: - New subdivisions must prove 100-year water supply - Well drilling is restricted - Water banking and credits are common
## Due Diligence for Buyers
### Municipal Water If connected to city water: - Verify service is established - Check monthly rates - Confirm no special assessments
### Well Water If using a well: - Test water quality - Verify well permit - Research aquifer sustainability - Check neighboring development plans
### Hauled Water Some rural properties require hauled water: - Factor in ongoing costs - Verify storage capacity - Understand restrictions
## Investment Implications
Water rights can significantly affect property values. Agricultural land with senior water rights may be worth multiples of similar land without rights.
