Tools and techniques

The purpose of this two-day thematic course is to provide you with an understanding of the principles, procedures and tools available for designing and managing a Non-Revenue Water (NRW) Programme in the most efficient and cost-effective way. Thus you will learn how to obtain reduced water losses, reduced pipe burst risks, and reduced energy consumption within a short period and with only a minimum of input data.

Optimal operation, maintenance and rehabilitation of water distribution systems constitutes a complex, complicated and often expensive process. 
DHI’s approach to NRW offers much more than Non-Revenue Water mapping – with short return on investment. Our solution to optimal Non-Revenue Water management works with the data that you have, follows international recommendations and uses a well-proven methodology in order to make your NRW management more structured and efficient – and it pays off from the beginning.
