The rainwater harvesting is a water management strategy that is becoming more and more common around the world. Due to the decrease in fresh water resources, development of rainwater harvesting systems (RHS) gain importance. This system, which is used to store the rain reaching the earth and use it to supply various types of water demands, is very easy to install. In this study, a water balance model (WBM) is run with different rain harvesting tank (RHT) sizes to find the best RHT sizes for a set of buildings at Middle East Technical University (METU) campus. A cost-benefit analysis is conducted to evaluate the financial feasibility of various RHT sizes and their performances are evaluated using performance indicators such as reliability, stormwater capture efficiency, water saving efficiency and overflow ratio. Generally, 25 m3 RHTs are found to result in the maximum net benefit for building groups of METU. However, dormitory buildings which are used by relatively more residents for longer times during the year and have smaller collection areas, require more collector area for their RHSs to be profitable.

Rainwater Harvesting Analysis for Northern Cyprus
Ruso, Mustafa; Akıntuğ, Bertuğ; Kentel Erdoğan, Elçin; Sustainable Environment and Energy Systems (2021-2)
Rainwater harvesting is a sustainable water resources management technique to harvest, store and reuse rainwater through rainwater harvesting systems (RWHSs). This study aims to determine the optimum rainwater storage (RWS) tank size of a RWHS to minimize the cost of water supplied from the utility network, wastewater cost and the RWS tank cost to attain the maximum financial benefit and analyze the rainwater harvesting potential for Northern Cyprus. A Linear Programming (LP) model is developed to achieve t...
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. ...
Water footprint assessment of mining and processing of gold
Güney, Emre; Demirel, Nuray; Department of Mining Engineering (2022-1-3)
Water management in mining industry has strategic importance due to the increasing water scarcity. Water Footprint Assessment (WFA) is a systematic way that provides an assessment of sustainable water management from multiple perspectives. The main objective of this study is to analyse the water footprint of mining and processing of gold and identifying hotspots of carbon in pulp (CIP) gold processing using WFA and life cycle assessment (LCA). In this study, after determining the goal and scope, data was co...
Investigating the applicability of water sensitive urban design techniques for Güzelyurt, Northern Cyprus
Elham, Jahani; Akıntuğ, Bertuğ; Sustainable Environment and Energy Systems (2017-2)
Water Sensitive Urban Design (WSUD) is a method used to mitigate the negative effect of urbanization on the water cycle. Due to a high percentage of impervious surfaces in urban area and reduction in the share of infiltration and evaporation, a considerable amount of rainfall is converted to runoff. This increase in runoff portion in urban areas causes serious problems for public and private properties. Moreover, the impact of climate change on more intensive rainfall events would cause serious problems tha...
Water recycling and reuse in soft drink/beverage industry: A case study for sustainable industrial water management in Turkey
Alkaya, Emrah; Demirer, Göksel Niyazi (2015-11-01)
The aim of this study was to investigate water conservation and reuse opportunities in a soft drink/beverage manufacturing company. Water use analysis and benchmarking were carried out to determine the areas and processes where significant water saving potential is present. Based on evaluations, water recycling and reuse practices were realized in cooling systems. As a result of applying these practices, the total specific cooling water demand of the company was reduced from 14.4 to 1.2 m(3)/m(3) product or...
