Working on behalf of the Sumitomo Corp and Brookfield Asset Management, IWS developed a Best Practice Document for non- revenue water management for use within the utility operations in Brazil where they jointly held an equity position.

Following an operational audit carried out by IWS in two of their utility businesses in Brazil, a number of key recommendations were made to improve operational efficiency, and a best practice document was developed to serve as a template and training tool across their entire utility portfolio.

As part of the assignment a number of management and staff familiarisation sessions were held to highlight the key aspects of operational best practice, and key features of the non-revenue water management process.
