2016/2017 NATIONAL PERFORMANCE REVIEW
2015/2016 National Performance Review data is included in the The International Benchmarking Network for Water and Sanitation Utilities (IBNET) database. This enables international comparisons of some performance indicators which can be accessed here.
Indicators in the national performance review do not always match IBNET indicators exactly. An FAQ sheet outlining the assumptions that have been used to map National Performance Review Indicators with IBNET can be accessed here.
