Rainwater harvesting has been used for thousands of years. Today, homes from Australia to Hawaii rely on it for indoor and outdoor water supply. Arizona ranchers began collecting rainwater many decades ago. This is an ancient, well proven method of adding high quality water to the community water supply. It works very well in our area with only 12" of rainfall.
Rainwater is better for plants than tap water – no salts or chlorine! There are no legal barriers to the use of rainwater for landscape use.
