WSO has been at the forefront of providing comprehensive water audit services to operators of public water supply systems since 2002. Our experienced personnel use the latest methodologies that are prescribed by the International Water Association and the American Water Works Association. We place particular emphasis on the validation of data used in the water audit and use statistical techniques to develop confidence grades for the audit results. Rigorous testing of the data ensures that your audit results are as accurate as possible.
WSO has also developed AuditSolve™, our own water audit software, to collate and present the water audit data and results in a standardised format. The software is designed to aid the user in making sense of the overwhelming quantity of data that is generated by a comprehensive water audit. The software incorporates the calculation of an extensive range of key performance indicators including ILI (infrastructure leakage index). It also includes variance analysis for calculation of overall audit accuracy and real loss component analysis.
