The nine-member team is building a rainwater-harvesting unit and filtration system as well as installing six biosand filters. The new tank will provide an additional 2,600 gallons of water for an orphanage in Choimim village that is home to nearly two dozen children, many of whom were abandoned in the tea fields, or abused.
The “first flush” filters will trap the initial rush of rainwater, which is filled with impurities that were resting on the roof (e.g. dust and pollen). The biosand filters purify the dirty water and make it safe to drink. They are very useful in rural and urban areas and are often adopted in areas that lack safe piped water.
