Public Perceptions On Water Reuse Options: The Case Of Sulaibiya Wastewater Treatment Plant In Kuwait

The main sources of water in Kuwait are seawater desalination and groundwater. Reclaimed wastewater effluent could be an additional water source. Its use would reduce the volumes of recycled water being disposed of to the environment and it could reduce the demand for fresh water supplies. The results of a questionnaire survey of more than 1,500 random households residing in 64 districts in Metropolitan Kuwait are presented. The frequency distribution of the education level, knowledge of wastewater reuse, age, nationality and gender of the sample population are presented. In addition, we have presented the results of a survey of attitudes amongst residents of their willingness to use reclaimed water for a variety of purposes. The research analyzes the costs and benefits of using reclaimed water. The study concludes with useful recommendations for both the authorities and the citizens of Kuwait

Water And Other Drinks Consumption Evaluation In Kuwait

The problem of securing and gaining reliable water supplies has been an issue of great importance to the people of Kuwait, ever since the earliest days of settlement in the region. The main objective of this paper is to analyze the Kuwaitis' attitudes concerning water and other drinks consumption. A simple, yet structured questionnaire, which provides the data base for the study was designed, presented, and employed in a person-survey of a random sample of 2,500 individuals residing in the six governorates of Kuwait. The frequency distribution of the type of water (tap, filter and/or bottled), number of classes of water, number of classes of other drinks, and other socio-economic characteristics of the sample population are presented. Results show that although an overwhelming majority of Kuwaitis know that drinking water is health enhancing, most do not drink as much per day as they should. Results also show that people in Kuwait consume a lot of dehydrating drinks. More importantly, this research establishes a baseline of information about public opinion, knowledge, and behavior regarding drinking water and other drinks, so that the impact of public education programs, in particular, may be assessed and measured in the future

Cost/Benefit Evaluation Of Sulaibiya Wastewater Treatment Plant In Kuwait

In May 2001, the Government of Kuwait awarded a build, operate and transfer (BOT) contract to a local company to finance, design, build and operate an advanced wastewater treatment plant (WWTP) at Sulaibiya. The contract has a 30-year life, comprising 30 months of design and build and 27.5 years of operation and management. The total project cost was K.D. 116 million (US 442 million). The Sulaibiya plant currently treats up to 375 million imperial gallons.  It is designed for extension to 600 million imperial gallons and is the first of its kind to be built in the Middle East.  It is the largest in the world to use ultrafiltration (UF) and reverse osmosis (RO) for water purification. Ultrafiltration will remove all suspended solids and will provide a substantial reduction in micro biological activities. The main obstacle against the use of ultrafiltration membranes for WWTP has always been the higher operating cost of ultrafiltration. Up until now, this higher cost has prevented implementation of UF in all plants. A new membrane has been designed with the aim of tailoring it toward lowest total cost of ownership. Typical operating conditions have been used to quantify the following parameters for a potential large scale wastewater treatment system (UF + RO): amortization of investment in UF membranes and equipment; operating costs of the UF system; reduction in operating costs of the RO, when being compared against a conventional treatment system; and the increased output of the RO plant due to higher availability and shorter construction time. The total cost of ownership of a UF based RO plant has been determined (expressed in US/m3 of water produced). Taking all factors into account, the total cost of ownership of a dual membrane WWTP (UF + RO) will be 2–7% lower than the total cost of ownership of on conventional retreatment plant

Water Distribution System Pipe Break Failure Modeling and Analysis: Case Study of Kuwait

The Ministry of Electricity and Water (MEW), as well as other water authorities all over the world, is facing a difficult challenge in assessing the physical condition of its distribution systems. Since the majority of the mains are buried, the MEW must rely upon indirect methods, including analysis of repair records. A case study on Kuwait’s water distribution system using the techniques of survival analysis is analyzed and investigated for modeling the pipe break failures. The proportional hazard model has the advantage of being able to separate the effects of component deterioration on failure due to aging from the effects of site-specific causes. Another desirable feature is its ability to analyze censored data. The sensitivity of the model parameters to sample size and percent censoring is examined through random sampling of the database. In addition, the proportional hazard model is suitable for describing failure rates of components
