To facilitate one small step towards a more sustainable future for Bangladesh, a rainwater harvesting system was installed at Baluakandi Dr. Abdul Gaffar High School and College in Munshiganj. The system is designed to serve 1200 students and staffs of the school during rainy season. The program was supported by San Francisco Art Institute, USA. Integration of enhanced knowledge of water, environment, sanitation, energy and sustainability was the prime objective. Workshop on necessity of rainwater harvesting for all the students and teachers was a part of the whole program.
