The document summarizes the BRAC WASH program intervention in Bangladesh. The program aims to improve sanitation coverage, hygiene practices, and reduce water-related diseases in 150 upazilas selected due to high poverty and arsenic contamination. The program uses approaches like forming village committees, capacity building, and school education. Evaluation of 30,000 households found improved water safety practices but sustainability issues. Ownership of sanitary latrines increased across economic groups, and reported water-related diseases reduced overall.
