„Roland Liemberger – Back to Basics – What you need to know about NRW assessment”.


It is already 20 years that the first edition of the IWA Manual of Best Practice, ‘Performance Indicators for Water Supply Systems’ had been published. It included the (then) new standardized water balance and water loss performance indicators. Since then Roland Liemberger has analyzed the NRW situation of water utilities around the world and has provided training to hundreds of engineers in many different countries. In this webinar Roland will explain the basics to those which are relatively new to the topic but also offer a few thoughts and tricks to the more advanced NRW engineer.
