Worldwide, Bangladesh is amongst the most affected countries with arsenic- and salinity-contamination in its drinking water resources. The combination of very high population density and widespread poverty in the country makes it a difficult challenge to identify appropriate water technologies to alleviate this problem. In the framework of the BRAC WASH II program, the ASTRA project aims to deliver an integrated and multifunctional sourcebook and decision-support tool. This tool is to feature all relevant drinking water methods for the Bangladeshi water sector. The sourcebook is based on a technological inventory aided by an interdisciplinary decision- and implementation-support module. From September 2014, the sourcebook and the decision-support tool are available both as an online portal and an offline booklet at



The ASTRA project aims to contribute to the Bangladeshi water challenge by developing a relevant water technology knowledge base enhanced with a decision-support component. This integrated compendium is designed to aid policy-makers, engineers and even less professional stakeholder groups (i.e. beneficiaries or donors) to help identify appropriate water technologies according to financial, environmental, institutional, technological, social, economic and management aspects.


  • a scientific and non-scientific inventory of current and upcoming arsenic- and salt-mitigation technologies, including alternative solutions in affected areas;
  • viewing of relevant water methods with the help of decision-support criteria, developed specifically for the Bangadeshi water sector;
  • assessment and of water method functionality of the relevant methods;
  • dissemination of the achieved results.
