One of the most important factors, while designing a water distribution system, is the storage tank capacity in terms of costs. When the storage tank volume is increased, more water can be stored, the water distribution system works more efficiently, and energy costs can be decreased. Population growth, interest rate, the cost of the water distribution system elements and energy prices have major effects on the storage tank capacity. The software model of the study area, N8.3, was optimized, and the daily energy costs of the 24 hour period simulation analysis were analysed. Costs of 24 hours period simulation of the scenarios, daily energy costs, were calculated for the years between 2015 and 2085. Results showed that the daily energy costs of the network decreased if the storage tank size increased. When the storage tank capacity is large enough, the storage tank can store more water in the lowest price intervals, and feeds the network for a longer period in the highest cost intervals. The requirement of the largest storage tank, which is selected within the scope of this study, occurred at the year 2055 when the interest rates are low. When the interest rate are high, the annual cost of the storage tank is greater than the annual costs of low interest rates. As a result of this, the largest storage tank requirement occurred later, after the year 2075, when the interest rates are high.

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. ...
Automated calibration of water distribution networks Apaydın, Öncü; Merzi, Nuri; Department of Civil Engineering (2013) Water distribution network models are widely used for various purposes such as long-range planning, design, operation and water quality management. Before these models are used for a specific study, they should be calibrated by adjusting model parameters such as pipe roughness values and nodal demands so that models can yield compatible results with site observations (basically, pressure readings). Many methods have been developed to calibrate water distribution networks. In this study, Darwin Calibrator, a...
Spatial data analysis for monitoring and prediction of selected water quality parameters in reservoirs: Porsuk Dam reservoir case Yenilmez, Firdes; Aksoy, Ayşegül; Düzgün, H. Şebnem; Department of Environmental Engineering (2014) In the design of a water quality monitoring network, selection of water quality sampling locations is crucial to adequately represent the water quality of the water body when high costs of analyses and field work are taken into account. In this study, a new approach was proposed to identify the representative water quality sampling locations in reservoirs and lakes using geostatistical tools for estimation of spatial distribution of selected water quality parameters. To do so, kernel density estimation (KDE...
Operation of water distribution networks Şendil, Halil; Merzi, Nuri; Department of Civil Engineering (2013) With continuously increasing urbanization, consumer demands and expansion of water supply systems, determination of efficient pump schedules became a more difficult task. Pumping energy costs constitute a significant part of the operational cost of the water distribution networks. This study aims to provide an effective daily pump schedule by minimizing the energy costs for constant and also for multi tariff of electricity (3 Kademeli Elektrik Tarifesi) in water distribution network. A case study has been p...
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 ...
