A decision support system (DSS) tool for the assessment of intervention strategies (Alternatives) in an urban water system (UWS) with an integral simulation model called ‘WaterMet2’ is presented. The DSS permits the user to identify one or more optimal Alternatives over a fixed long-term planning horizon using performance metrics mapped to the TRUST sustainability criteria. The DSS exposes lists of in-built intervention options and system performance metrics for the user to compose new Alternatives. The quantitative metrics are calculated by the WaterMet2 model, and further qualitative or user-defined metrics may be specified by the user or by external tools feeding into the DSS. A multi-criteria decision analysis approach is employed within the DSS to compare the defined Alternatives and to rank them with respect to a pre-specified weighting scheme for different Scenarios. Two rich, interactive graphical user interfaces, one desktop and one web-based, are employed to assist with guiding the end user through the stages of defining the problem, evaluating and ranking Alternatives. This mechanism provides a useful tool for decision makers to compare different strategies for the planning of UWS with respect to multiple Scenarios. The efficacy of the DSS is demonstrated on a northern European case study inspired by a real-life UWS for a mixture of quantitative and qualitative criteria. The results demonstrate how the DSS, integrated with an UWS modelling approach, can be used to assist planners in meeting their long-term, strategic-level sustainability objectives.
Forensic Analysis of Horizontal Well Systems - Case Study
Project Location: Eastern New York Client: Public Utility – Major Airport Contamination: Jet Fuel Site Size: 10+ Acres Project Description: Having contracted with a large nationally known Environmental Remediation Company to design and install numerous horizontal well deployed AS and SVE systems to clean up their extremely large plume of JP fuel, a major east coast Client became very concerned that the firm`s systems were not functioning as routinely reported (and hence, remediation was...
Wind-powered water pumping for irrigation and water supply - Case Study
Introduction Access to clean water is of paramount importance for ensuring necessary levels of sanitation and health. According to the World Health Organization over 844 million people lack even a basic drinking-water service, including 159 million people who are dependent on surface water. Globally, at least 2 billion people use a drinking water source contaminated with feces. Contaminated water can transmit diseases such diarrhea, cholera, dysentery, typhoid, and polio. By 2025, the WHO estimates half of the...
Ask the Expert: Oil Analysis in Power Generation
Uptime is one of the key considerations for all power generators. Electricity supply must equal demand at all times. Downtime, especially unplanned downtime, is very difficult to deal with and can be quite costly. Fortunately condition based monitoring can go a long way towards preventing unscheduled downtime and achieving uptime goals in excess of 98%. In particular, on-site oil analysis is a key tool used by power generators to avoid unplanned outages. Power generators are familiar with oil analysis and have...
Application of Lab-on-a-chip Technology in Water Analysis
The Important of Water Analysis Water analysis is essential to ensure its quality or to detect pollutants that should be removed by water treatment. However, water quality does not mean making the water suitable for human consumption; it depends on its end use. For example, completely different quality standards are applied in case of industrial water compared to those applied to drinking water, i.e., drinking water must be fit for human consumption, while industrial water should be free from any contaminants...
