Recent research presented at the IWA Water and Development Congress in Buenos Aires (2017) has shown that the global volume of NRW is estimated to be 346 million cubic meters per day or 126 billion cubic meters per year. Conservatively valued with only USD 0.31 per cubic meter, the cost/value of water lost amounts to USD 39 billion per year. Sadly, around 80% of these losses occur in low and middle income countries.

Learning Objectives

Non-revenue water (NRW) management can deliver significant health, systems, and financial and economic benefits, but not all professionals know where to start. This training will provide participants with an understanding from assessing Non-Revenue Water to developing and implementing improvement plans.
The workshop will be tailored to meet the requirements of the mixed audience you normally expect at the IWA World Water Congress. A role play will be convey the key messages in a way that will make it interesting and useful for key decision makers and other non-experts which are not so close to technical details.

After this training, you will have a good understanding on:
How to assess the NRW problem in a water utility
Preparation of an NRW reduction plan
Simple ways to do an initial cost benefit analysis
Problems of starting to engage in comprehensive NRW

On top of these learning objectives, participants will have the chance to directly be in contact with top experts from around the world.
