Benchmarking, collecting performance indicators and then comparing performance among utilities of similar size and conditions, is a major tool to improve water utility performance. Several benchmarking activities exist to support the collection of performance indicator data on Danube regional, national and utility level.

The National PI Data Collection is a key activity supported under the Danube Water Program. It resulted in the development of the DANUBIS Data Collection and Management Platform (DANUBIS DCM), which is designed as a separate, online data collection and management platform to allow national institutions to easily collect, validate, manage, share and publish utility performance data.

The Utility Benchmarking Program (UBP) operated under D-LeaP assists utilities in collecting their performance data, in assessing the data to identify areas, where performance improvement is needed, and finally improve the performance through knowledge exchange with peers. stands for Danube Utility Benchmarking and Information Sharing. The PI Database is a regional public performance indicator database of water supply and sanitation utilities in Southeast, Eastern, and Central Europe.
