"Rain water is a largely untapped resource, especially in many developing countries where clean water is scarce. Water harvesting consists of three main components: a catchment area (generally a roof), a gutter system and a water storage area. The water storage area is by far the most expensive portion of this system, which makes it out of reach for many families. 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."
