Water Stewardship Australia (WSA) offers a tool, a system and a governance process to engage, recognise and reward water using sites (particularly the private sector) for adopting and implementing collaborative, holistic water management plans intended to achieve four outcomes; sustainable water balance, good water quality, healthy water related ecosystems and cultural sites and good water governance. The water stewardship system is built around the AWS International Water Stewardship Standard (which draws on work started in Australia where WSA developed the world’s first water stewardship standard). It includes a verification system to establish compliance, a multi-stakeholder governance system and a brand to recognise water leadership by industry. WSA supports businesses, industries, governments, catchment agencies and NGOs seeking to engage water using sites in addressing ‘water challenges’ using the framework of the AWS Standard. WSA was a founding member of the international Alliance for Water Stewardship (AWS). It is the current chair of that organisation and operates with and on behalf of AWS in the Indo-Pacific region.
