Author: V. Kanakoudis and S. Tsitsifli

Year: 2009

Publisher: European Water Resources Association (EWRA)

Description:

The whole world is experiencing water shortage and climate change conditions more than ever, driving all the people involved (governments, water utilities, stakeholders, etc.) to manage water resources more efficiently. Water losses in urban water distribution networks due to leaks and breaks are almost one third of the water supposed to be supplied to the citizens. Water Utilities must take radical measures in order to significantly reduce the levels of Non-Revenue Water (NRW). Therefore, the IWA standard international water balance and some of the related performance indicators (PIs) are being calculated in this paper. The Larisa city case in Greece was chosen as a case study in order to identify the problems faced during the implementation process and find out ways to tackle them. A city in Greece was chosen especially because the country is facing water shortage problems and Greek Water Utilities miss many of the most important data for the implementation of the water balance and the  calculation of the PIs.
