|The Rain Drops by Evan Gant. Rain Drops designed for collecting Rain water from the roof. You just modify the existing gutter system. The rain water will store in many standard plastic bottles, you can use it water your garden or washing your hands! I love this idea!
"The RainDrops system simply allows people to adapt standard plastic bottles to an existing gutter system to collect rain water. This changes water storage from the most to the least expensive part of the system. These are much easier to clean and replace than larger storage units. The repurposing of these plastic bottles will also give value to many bottles that are otherwise headed for landfills. Corruption in the water sector is a real problem in many developing countries. The scalability of this system helps to give more power to the communities in need.
Another large benefit to using plastic bottles as a water collection system is that it fits in nicely with the process called SODIS, which uses a combination of the suns UV rays and heat to remove pathogenic microorganisms that cause disease. This process is spreading across many developing countries due to its effectiveness and low cost. "
