How to sustain rooftop rain water harvesting initiatives in coastal Bangladesh?

Well designed and hygienically managed rooftop rainwater harvesting systems can offer proper drinking-water to communities, one of the important goals under SDG6.

As part of the WASH Alliance SDG program in Bangladesh, two coastal municipalities – in Satkhira and Barguna district – have been selected to pilot an innovative business approach to implement rooftop rainwater harvesting systems. The aim is to improve access to clean drinking water for the communities, since currently, 17% of the population have to walk over 30 minutes to the nearest water point. Often these are contaminated as well. Also, using rainwater will reduce usage of the scarce groundwater resources.

The sustainability of the program activities is secured by

  • Strengthening the capacity of WASH-entrepreneurs;
  • WASH-entrepreneurs offer design-build and maintain services to beneficiaries and
  • Beneficiaries are financially capacitated through micro-credit support.

Last Wednesday RAIN, an Aidenvironment brand, trained an enthusiastic team of NGO Hope For The Poorest (HP), municipal officers and other SDG-partners on the technical aspects of rooftop rainwater harvesting. Especially those aspects that help to sustain the systems, including necessary water quality pre-cautions.

This training was a first step in the Dutch-Bangladesh cooperation in the Coastal Belt of Bangladesh. Next steps of the pilot will be;
the identification of beneficiaries and suitable locations for rooftop rainwater harvesting systems, as well as, capacitating existing WASH sector entrepreneurs on rooftop rain water harvesting.
RAIN will support HP with technical expertise.
