First, Trulia, Zillow, Yahoo and other national sites are frequently out of date and over half of their listings are no longer available. Please use my local website http://www.CentralAZHomes.com to search. It is updated hourly and you can stay on top of what is currently available.
In this case the listing specifies that the water is hauled. Each home will have a different water situation. Water wells are different from home to home. It is not a good idea to lump them different homes in to one category. If the home you are considering has a well, require the seller pay to have the well tested to determine the wells performance.
Be sure you include the Arizona Realtors' Domestic Water Well Addendum in your offer. Even if you can't get the Seller to pay for the Well inspection, pay to have it done yourself. Determine water quality and flow rate and equipment condition.
If you are on a shared well system (like 2-5 other homes sharing one well), you need to talk to the neighbors (all of them) to see how their cooperative is working. Investigate the governing paperwork, check the cash reserves they have, is the well properly maintained, who is in charge, plus much more. Get a lawyer to review the well agreement. Some of these deals are fraught with risk, especially when one owner stops paying their fair share or is having financial difficulties.
Last but not least, I suggest you select a Real Estate Buyer's agent to represent you that is knowledgeable about water wells to help you through the process. Don't forget to check out the septic system too.
