Excessive water loss from drinking water distribution network is a serious problem in many countries all over the world including Turkey where total water losses is around 45% of the distributed water. Water loss not only cause a critical amount of energy and economic losses but also results in water quality and sustainability problems. Thus it is crucial to determine, reduce and manage water loss. The most effective means of reducing water loss in distribution systems is proven by former studies to be the control of excessive pressures in the network. In this study, an optimization method is developed to minimize leakage in a water distribution system by pressure reducing valves (PRV) usage. The aim is to optimize tolerance, which is the difference between existing and predefined minimum allowable nodal head, while considering pressure head limitations and PRV settings. The leakage is expressed as a function of pressure, due to the strong correlation between them. In addition to that, chance constraint is applied to cover uncertainties in the system which are resulting from the change of roughness height of pipes with time. Network hydraulics and optimization model are solved by simultaneously using EPANET and GAMS, respectively.

Leakage optimization of water distribution networks by pressure control
Köker Gökgöl, Ezgi; Altan, Tomris Elvan; Department of Civil Engineering (2018)
Excess water losses from drinking water distribution network is a serious problem in many countries all over the world including Turkey where total water losses is around 40% of the distributed water. Total water losses are divided into two parts namely (i) apparent or commercial water loss and (ii) real or physical water loss. Apparent water loss is from sources such as illegal water usage (water theft), inaccuracy in customer water meters, and meter reading handling errors. Real water loss is from sources...
Rehabilitation of water supply systems
Toğrul, Nevzat; Merzi, Nuri; Department of Civil Engineering (2015)
Management of water supply systems by an economic and efficient way is a significant issue for water authorities. Selection and operation of water supply elements appropriately to satisfy water need affects the energy consumption of the system. This study aims to constitute a long term rehabilitation plan for water supply elements (only storage tanks, pumps and transmission line pipes are in the scope of the study). A case study has been performed on N8.3 pressure zone of Ankara water distribution network. ...
Experimental Study on Maize Cob Trickling Filter-Based Wastewater Treatment System: Design, Development, and Performance Evaluation
Ali, Imran; Khan, Zahid M.; Sultan, Muhammad; Mahmood, Muhammad H.; Farid, Hafiz U.; Ali, Mohsin; Nasir, Abdul (HARD Publishing Company, 2016-01-01)
In developing countries, good-quality water is contaminated due to the disposal of untreated municipal and industrial wastewater (WW) into natural water reservoirs. Most of the wastewater is not treated properly according to international standards, and usually is disposed of and/or utilized for irrigation without appropriate treatment. The main hurdles in providing wastewater treatment (WWT) in developing countries include high costs, and the poor design, installation, and operation of conventional WWT sys...
Chance constrained optimization of booster disinfection in water distribution networks
Köker, Ezgi; Altan Sakarya, Ayşe Burcu; Department of Civil Engineering (2011)
Quality of municipal water is sustained by addition of disinfectant, generally chlorine, to the water distribution network. Because of health problems, chlorine concentration in the network is limited between maximum and minimum limits. Cancerogenic disinfectant by-products start to occur at high concentrations so it is desired to have minimum amount of chlorine without violating the limit. In addition to the health issues, minimum injection amount is favorable concerning cost. Hence, an optimization model ...
Management of disalination brine in Qatar and the GCC countries
Sezer, Nurettin; Evis, Zafer; Koç, Muammer (null; 2017-06-30)
Reliance on desalinated water has been ever-increasing due to increase in population and over-exploitation of natural fresh water resources. Desalination process produces fresh water at the expense of natural environment. Desalination waste, known as brine, is the major pollutant of seawater. However, there has not been a unique brine management technology that could work effectively everywhere. Therefore, effective processes are required to treat and manage the brine specific to the desalination plants. In...
