1. Can I turn my swimming pool into a cistern?
Yes, the swimming pool can be used as the rainwater storage tank. Precautions include using a food-grade lining (especially if water is to be used on vegetable gardens), ensuring structural integrity of pool system either with crates or poles and ensuring the cover is sealed to prevent mosquito problems.
2. How can I tell how many inches of water I will get depending on the month/during the year?
3. Are there requirements for how many inches of water a cistern needs to capture?
Originally the rebate required systems to capture 1” of rainfall for the roof area the system was capturing from. This was incredibly complicated to manage, so the amount was changed to a flat rate, but given that these are expensive systems and the goal is to capture water for future use, we encourage people design their systems to capture at least 1” of rainfall or more, to maximize the amount of water they can collect. More information is available on our Workshops and Project Plans web page.

In the county, see the Pima County of Ordinances, Title 18 – Zoning, Chapter 18.07.030, Land Use Regulations, Section R. Rainwater Harvesting System .
