The Global Water Tool is a free and easy-to-use tool for companies and organizations to map their water use and assess risks relative to their global operations and supply chains. It compares a company’s sites with validated water and sanitation data on a country and watershed basis. The tool also helps companies understand their water needs in relation to local conditions, such as water availability (current and projected), water scarcity, access to safe drinking water sources and sanitation, as well as population and industrial growth. This online, Excel-based platform takes a company’s water usage data and maps its operation sites with external water and sanitation datasets. Looking beyond operational water use, supplier site locations may also be mapped as well.
