Water purification has been a major problem on barangay molos, along with the difficulty in giving a solution to their problem in fecal coliform presence in the source of their drinking water. Despite the DOH programs regarding water sanitation, the barangay still has less knowledge on water purification methods and resulting to the basic ones such as chlorination and boiling which has a major disadvantage on the taste of the water. The team has thought of implementing a lecture and demonstration on small biosand filter and solar disinfection, promoting it on every households. Small BSF and Sodis is by evidence a very effective method in eliminating the coliform present in the barangay's drinking water source. It has proven that it is cheap, accessible and effective in purification, during the lecture and demonstration the barangay has opted for an actual workshop bringing along the needed materials for the construction of the Small BSF and the PET bottles.
