Applying an integrated methodology toward non-revenue water reduction: the case of Nicosia, Cyprus
Kanakoudis, V.; Tsitsifli, S.; Demetriou, G. (2015)Non-Revenue Water (NRW) is one of the major issues water utilities are facing today, especially in areas with severe water scarcity conditions. The WATERLOSS-DSS, a user friendly decision support system (DSS), was developed ... -
Assessing the performance of urban water networks across the EU Mediterranean area: The paradox of high NRW levels and absence of respective reduction measures
Kanakoudis, V.; Tsitsifli, S.; Samaras, P.; Zouboulis, A. (2013)The aim of this paper is to assess the performance level of water distribution systems (WDS) in six areas located in four Mediterranean countries, and evaluate their common characteristics. The second modification of the ... -
Basic Principles of a DSS Tool Developed to Prioritize NRW Reduction Measures in Water Pipe Networks
Kanakoudis, V.; Tsitsifli, S.; Cerk, M.; Banovec, P.; Samaras, P.; Zouboulis, A. I. (2015)Non-revenue water (NRW) in urban water distribution networks is a very demanding task to handle. NRW impacts are economic (lost revenues), environmental (water and energy losses) and social (inefficient water pricing ... -
Defining the level of the Non-Revenue Water in Kozani, Greece: is it a typical case?
Kanakoudis, V.; Tsitsifli, S.; Kouziakis, C.; Lappos, S. (2015)Water Losses in pipe networks usually represent the biggest "water use" due to the high leakage occurring. Water utilities are forced to apply effective Non-Revenue Water (NRW) reduction strategies, as climate change ... -
Domestic water pricing in Greece: a spatial differentiation
Kanakoudis, V.; Papadopoulou, A.; Tsitsifli, S. (2015)This study investigates the differentiation of the water pricing policies applied by the Greek Municipal Water Utilities (GMWU) in several regions. GMWU are being characterized by individual management framework with a ... -
DOMESTIC WATER PRICING IN GREECE: MEAN NET CONSUMPTION COST VERSUS MEAN PAYABLE AMOUNT
Kanakoudis, V.; Papadopoulou, A.; Tsitsifli, S. (2014)The water utilities in Greece that are responsible for the development of domestic water pricing policies, are municipal enterprises (called DEYA). They are public agencies that are autonomous and have almost identical ... -
Evaluating the performance level of a water distribution network under unbalanced operating conditions - The case of Kos Town (GR)
Kanakoudis, V.; Tsitsifli, S. (2010)The need for a common international terminology is growing the last few years regarding the performance evaluation of urban water distribution systems, due to the wide diversity of definitions used across the word (even ... -
Integrating the Carbon and Water Footprints' Costs in the Water Framework Directive 2000/60/EC Full Water Cost Recovery Concept: Basic Principles Towards Their Reliable Calculation and Socially Just Allocation
Kanakoudis, V.; Tsitsifli, S.; Papadopoulou, A. (2012)This paper presents the basic principles for the integration of the water and carbon footprints cost into the resource and environmental costs respectively, taking the suggestions set by the Water Framework Directive (WFD) ... -
A new set of water losses-related performance indicators focused on areas facing water scarcivty conditions
Kanakoudis, V.; Tsitsifli, S.; Samaras, P.; Zouboulis, A.; Banovec, P. (2013)As almost all Mediterranean countries are facing water scarcity problems today, water losses in drinking water supply networks have grown to an urgent problem, needing immediate confrontation, representing a too valuable ... -
On-going evaluation of the WFD 2000/60/EC implementation process in the European Union, seven years after its launch: are we behind schedule?
Kanakoudis, V.; Tsitsifli, S. (2010)Although the European Union (EU) has made some considerable progress regarding protection of water resources (tackling significant problems at national and at EU level), increased efforts are still needed to get and keep ... -
Overview of the River Basin Management Plans Developed in Greece Under the Context of the Water Framework Directive 2000/60/EC Focusing on the Economic Analysis
Kanakoudis, V.; Tsitsifli, S.; Azariadi, T. (2015)The most important piece of legislation towards integrated water management in Europe is the Water Framework Directive 2000/60/EC (WFD) based on the river basin. During its implementation each Member State (MS) should ... -
Pipe Networks Risk Assessment Based on Survival Analysis
Tsitsifli, S.; Kanakoudis, V.; Bakouros, I. (2011)Integrated management of pipe networks should include methods for monitoring, repairing and replacing deteriorating components (usually pipes), but also methods and everyday operating practices towards a proactive risk ... -
Predicting the behavior of a pipe network using the "critical Z-score" as its performance indicator
Tsitsifli, S.; Kanakoudis, V. (2010)The paper deals with pipe reliability assessment in two networks using the Discriminant Analysis and classification (DAC) method. The pipes of each network are divided in two groups based on whether they failed at least ... -
Results of an urban water distribution network performance evaluation attempt in Greece
Kanakoudis, V.; Tsitsifli, S. (2010)The need for efficient water resources management is currently more pressing than ever, considering population growth and increased reliability requirements, under climate change conditions. On average, one-third of the ... -
