Stand Alone Rainwater Harvesting System
Rain and Solar Powered Outdoor Shower
by RainSaucers Inc. on August 15th, 2012

Solar powered outdoor showers are becoming more common these days as folks have begun to realize just how easy it is to use the sun to heat water. The residential models we've seen use a garden hose hookup and a black vertical shower tower to get about 10 gallons worth of hot water. Meanwhile camping versions use a 5 gallon black bag which you heat then suspend from a tree. Both are great concepts but they have a major dependency- access  to clean water, which may not be on hand in developing countries. As a RainSaucers fan who frequently travels to Mexico pointed out to us recently, poor rural families have enough trouble finding water to drink and cook let alone take a shower.

So that got us thinking about a solar outdoor shower with its own independent water supply from rain. All it would take is two rain barrels: one painted all-black (for hot water), and one covered in a tarp (for cool water) suspended at least 6 feet off the ground (we have seen such stands, they look like tripods). Each barrel would have its own faucet piped into a third faucet with a shower attachment, just like you would expect. A single 59" RainSaucerâ„¢ would be deployed permanently on the cool rain barrel with the first (hot) and second (cool) faucets left open. After an inch of rain, both barrels would have 5 gallons (the open faucets allow for simultaneous fill), enough for a nice shower. When the sun comes out the black barrel would be in full sun for maximum heat while the covered barrel would stay cool under the tarp and shade from the RainSaucerâ„¢. The user could then adjust the release of hot and cool to find the right temperature. For privacy, a rope run between the cool barrel stand and a tree or post could easily support a shower curtain.

P.S. If anyone reading this is interested in such an application of the RainSaucerâ„¢, please contact us. We would be happy to support such testing.
