The RainDrops system allows people to adapt standard plastic bottles to an existing gutter system to collect rain water. The repurposing of these plastic bottles will also give value to many bottles that are otherwise headed for landfills.
A 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.
