According to recent statistics there are still more than a billion people across the globe lacking access to clean drinking water. While researchers and non-government organizations are trying to come up with easy to use water filtration systems, most of them cannot be afforded by people living in such areas. Chris Grant, a Medford-based entrepreneur, has now tried to solve the issue with an innovative rainwater harvesting and purification system that can produce 120 gallons of purified drinking water by harnessing water from one-inch of rainfall.
Chris states that the system is an alternative to having to walk up to 30 miles a day and carry water from a source in a bucket. The Waterport system consists of a roof that collects rainwater through pipes. This rainwater is then relayed to two different filters – the first one making use of sand, gravel and charcoal to remove sediments and odor, and the second is an ultraviolet filter that runs on solar energy collected by a solar panel affixed to the structure.
The result of the filter is 99.9 percent pure water. Waterport costs about $2000 and Chris believes that the primary clients for such a system would be NGOs and people living in developing countries who have the money but no access to safe drinking water. According to Chris, it rains about 20 inches in several parts of the world where access to potable water is limited. While most of this water goes to waste, the Waterport system can use it to produce over 5000 gallons of purified water each year.
