Main Goal: to provide the means for at least 20% of the community to have access to clean potable water. This would mean developing water filtration systems that will be easily built, maintained, and used by the people in the community.
Main Design: currently we are actively developing our version of a biosand filter. This would be a water filter unit made of a concrete shell and filled with native sand. The unit operates by creating a mini-ecosystem within the filter to naturally remove bacteria, protozoan, and various undesirables. The large volume of sand will also work to mechanically remove particles from the water just like the ceramic filters in the bucket units, which disallows anything larger than 5 microns from passing through. Each unit is designed to provide enough water for 6 people per day.
