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 ... -
Assessing the impact of dmas and the use of boosters on chlorination in a water distribution network in Greece
(2021)Disinfection is one of the most important water treatment processes as it inactivates pathogens providing safe drinking water to the consumers. A fresh-water distribution network is a complex system where constant monitoring ... -
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 ... -
Epidemiological investigation of Legionella pneumophila serogroup 2 to 14 isolates from water samples by amplified fragment length polymorphism and sequence-based typing and detection of virulence traits
(2016)The aim of this study is to explore the dispersion, clonality, and virulence of Legionella pneumophila serogroups 2 to 14 in the Greek environment. Eighty L. pneumophila serogroup 2 to 14 strains isolated from water ... -
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 ... -
Evaluating the performance level of a water distribution network under unbalanced operating conditions - The case of Kos Town (GR)
(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 ... -
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 ... -
Identification of Suitable Locations in a Small Water Supply Network for the Placement of Water Quality Sensors Based on Different Criteria under Demand-Driven Conditions
(2022)Drinking water quality monitoring in real time is of utmost importance to ensure public health. Although water utilities, following the related legislative framework, monitor drinking water quality through samplings, the ... -
An integrated urban water management scheme: From source to tap
(2018)Urban water systems have great potential in water and energy saving. A thorough water losses component assessment can reveal this potential and drive utilities into a proper water management scheme towards a more sustainable ... -
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 ... -
Micromixing efficiency of particles in heavy metal removal processes under various inlet conditions
(2019)Water quality problems are a persistent global issue since population growth has continually stressed hydrological resources. Heavy metals released into the environment from plating plants, mining, and alloy manufacturing ... -
