People for Rainwater

Sustainable rainwater project to secure safe drinking water

Activity grant

Project Description

One of the UN's Millennium Development Goals is to halve the global population without access to safe drinking water by 2015. Bangladesh falls short of WHO standards in this respect with an estimated 40 million people using arsenic contaminated drinking water, and salt contamination is increasing due to rising sea-levels and shrimp breeding. People for Rainwater has been introducing rainwater usage technology developed in Japan as part of international cooperative initiatives since 2000, but has experienced problems such as insufficient tank storage capacity, a lack of maintenance, and a dependency on overseas funding making activities unsustainable. Therefore this project aims to standardize the rainwater technology used by:
(1) trialing standardized low-cost tanks and providing training for local people and leaders,
(2) collaborating with local NGOs to raise awareness,
(3) cultivating technicians,
(4) investigating microcredit needs in relation to tank installation and implementing a pilot scheme.
