Nirmala, Primary school Teacher, Chennai,

“Our school serves nearly 60 children, and previously, we lacked safe drinking water. Thankfully, our situation has improved significantly since we received Terrafil water filters and our children and are really happy.”

“Previously, women and girls here had to defecate in the open, facing dangers from animals and harassment from people hiding in the bushes, especially under the worse conditions of the rainy season with knee-deep floods. Now, with access to proper toilets, we are free from the fears of open defecation and can feel safe from both human and animal threats. This change has greatly improved our dignity and quality of life.”

“I had my toes amputed due to an accident. Over time, I developed gangrene and water used to ooze out when I tried to balance my weight and walk. So I needed assistance to find a secluded spot to and did not eat during the day when my wife was away due to this. With an ecosan at home, I eat well and use the toilet independently. Thanks to Sanitation First for helping me regain my dignity and live a normal life.”
