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.
Get Schooled in Water Safety and Microbial Monitoring with LuminUltra Academy
It’s not often you come across a company so committed to educating its customers and partners that it develops an entire suite of training courses, but that’s exactly what led to the creation ofLuminUltra Academy. Access to this new, web-based training and certification center is available to anyone with an interest in learning more about how to monitor and manage the risks posed by microorganisms in water systems. LuminUltra Academy was developed by the team at LuminUltra, a firm dedicated to...
Case study - Monitoring underground water resources in Brazil
Monitoring underground water resources in BrazilThe Coca-Cola FENSA plant in Mogi das Cruzes is responsible for bottling mineral water supplied from two ground water sources. The plant is a benchmark for environmental sustainability projects. With this pioneer project the Mogi das Cruzes plant was the first of the Coca-Cola FENSA Group to install an online analysis monitoring, using the OTT PLS and OTT DuoSens datalogger, along with other Hach technologies. Monitoring Solution The monitoring system consists of...
How much will a zero liquid discharge system cost your facility?
With increasing stewardship of environmental protection, both nationally and internationally, many industrial facilities and effluent regulators are strengthening strategies to reduce industrial process waste by implementing zero liquid discharge (ZLD), a process that limits liquid waste at the end of your industrial process to—as the term suggests—zero. A more recent example of how ZLD is being recommended for tightening effluent regulations is the new mandates passed by the U.S. Environmental...
Economic feasibility of rainwater harvesting systems: a systematic literature review
Rainwater harvesting (RWH) systems are increasingly being used as an alternative source of water supply. However, their installation is not often financially feasible. The feasibility analysis of such investments is carried out by traditional techniques that have uncertainty limitations. Thus, the objective of this study is to describe how the studies concerning the economic feasibility of RWH systems have been conducted, thus identifying trends of current studies through a systematic review. We performed a...
Case study - SEAWATCH Vietnam
After a series of marine disasters in Vietnam a project was initiated on the initiative of the United Nations (UN) to improve the typhoon forecasting and warning system, described and defined in the UN report "Strategy and Action Plan for Mitigation Water Disasters in Viet Nam".The United Nations (UN) initiated a plan to mitigate the effects of natural disasters occurring in Vietnam. The UN report "Strategy and Action Plan for Mitigating Water Disasters in Vietnam" recommended several measures to be taken. To...
