So, if a small and compact rain barrel isn't what you had in mind, you could always do what Jerry Block did: other than the 20,000 gallon rain water collection system and four massive holding tanks in his backyard in Monte Sereno, CA, his home is pretty ordinary. See what use Jerry has for all that water after the jump ...
20,000 gallons would last some households an entire year. Granted, Jerry has something very green in mind for all that water. In his backyard, Block has about an acre of land on which he grows fruit, vegetables and some tree crops that produce enough food for two people each year. According to Block, his new rainwater collection system is sized appropriately based on the rainfall in Monte Sereno, and the water required to irrigate his land.
Block has considered using water from the system for the toilets, but because rainwater is technically gray water, he'd have do some additional work. The system cost Block approximately $29,000, and was made by Rain Harvesting Systems and Gutterglove.
