Applying pressure management to reduce water losses in two greek cities' WDSs: Expectations, problems, results and revisions
(2014)An overall pressure management project applied in two (Kos and Kozani) different water distribution systems in Greece is presented. The two Water Utilities developed a pressure management strategy. In both cases, Watergems ... -
Basic Principles of a DSS Tool Developed to Prioritize NRW Reduction Measures in Water Pipe Networks
(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 ... -
Combining pressure management and energy recovery benefits in a water distribution system installing PATs
(2017)Gravity can play a beneficial role in certain water distribution networks (WDNs), although sometimes high nodal pressures occur. Excessive pressure may lead to several negative effects regarding the network's operation and ... -
Developing an Optimization Algorithm to form District Metered Areas in a Water Distribution System
(2016)Exploiting the numerous possibilities that unfold from the inter-connection of Matlab and Epanet software, an algorithm is produced in C++ language. The algorithm reads all the significant data of the water distribution ... -
Developing THMs' predictive models in two water supply systems in Greece
(2020)Disinfection is a very significant water treatment process for drinking water safety, as it inactivates pathogens from drinking water. However, disinfection-by-products (DBPs) are formed which are accused of contributing ... -
Estimation of crop water requirements using remote sensing for operational water resources management
(2015)An integrated modeling system, developed in the framework of "Hydromentor" research project, is applied to evaluate crop water requirements for operational water resources management at Lake Karla watershed, Greece. The ... -
Forecasting the residential water demand, balancing full water cost pricing and non-revenue water reduction policies
(2014)The paper examines the factors that determine the residential water demand level in the city of Kozani located in the NW part of Greece. Based on an 8-year (2005-12) detailed sample of residential water demand time panel ... -
Forming District Metered Areas in a Water Distribution Network Using Genetic Algorithms
(2016)Dividing a water distribution network into District Metered Areas (DMAs) is the first vital step towards water loss management. It is a multivariate problem. Techniques based on Genetic Algorithms is a proven way to provide ... -
The joint effect of water price changes and pressure management, at the economic annual real losses level, on the system input volume of a water distribution system
(2015)This study attempts to examine the factors affecting the residential water demand level in the city of Kozani in Greece. Based on an 8-year (2005-12) detailed sample of residential water demand panel data, the values of ... -
A new set of water losses-related performance indicators focused on areas facing water scarcivty conditions
(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 ... -
The optimal balance point between NRW reduction measures, full water costing and water pricing in water distribution systems. Alternative scenarios forecasting the Kozani's WDS optimal balance point
(2015)The paper summarizes the final outcome of a study that lasted three years and deals with NRW reduction measures, the FWC integration in water price and the consumers' response to water price changes. Each term of the above ... -
Policy recommendation for drinking water supply cross-border networking in the Adriatic region
(2017)Cross-border water resources and drinking water supply management are among the basic concerns for almost all Adriatic Sea countries. Adopting measures such as developing common methodologies, tools and techniques addressing ... -
Pressure Management and Energy Recovery Capabilities Using PATs
(2016)Hydro-turbines are widely used in small water energy production plants in order to turn water kinetic energy to electricity. PATs (Pumps working As Turbines) are micro-turbines (small sized compared to the usual ones) ... -
Reaching economic leakage level through pressure management
(2016)High non-revenue water (NRW) values as a percentage of system input volume form a serious problem that many water utilities worldwide have to confront nowadays. There are ways to mitigate the effect by adopting strategies ... -
Soft computing approaches for urban water demand forecasting
(2016)This paper presents an integrated framework for water resources management at urban level which consists of a Neuro-Fuzzy and Fuzzy Cognitive Map-based, (FCM) decision support system (DSS) based on multiple objectives and ... -
Urban water demand forecasting for the Island of skiathos
(2014)We present an analysis of historical water demand data from the utility of Skiathos, Greece and demonstrate suitable demand forecasting methodologies. We apply linear and nonlinear forecasting methods to a three-year time ... -
Water Pipe Networks Performance Assessment: Benchmarking Eight Cases Across the EU Mediterranean Basin
(2015)The high level of the non-revenue water (NRW: water not generating revenues) is a well-acknowledged problem water utilities are straggling with in areas facing water scarcity. High NRW values jeopardize the sustainability ... -
WATERLOSS project: developing from theory to practice an integrated approach towards NRW reduction in urban water systems
(2015)Today almost all Mediterranean countries are facing significant water scarcity problems; therefore, water losses in drinking water supply networks have grown to an urgent problem, requiring the implementation of immediate ...
