InfoWorks addresses Critical link
Analysis
Wallingford Software, a leading developer of hydraulic modelling and network data management software for the worldwide water industry has revealed plans to release Critical Link Analysis.
Wallingford Software, a leading developer of hydraulic modelling and network data management software for the worldwide water industry has revealed plans to release a new tool, Critical Link Analysis, that will feature in the next release of InfoWorks This additional tool, used to identify critical network links, has been developed in response to the requests of modellers worldwide and is planned for launch towards the end of the autumn

InfoWorks CS Software For China Sewer Masterplan
InfoWorks CS, the hydraulic modeling solution for urban drainage, has been selected as the modeling platform for a major sewer project in the Chinese provincial city of Hangzhou.
When asked why the tool was needed, Paul Banfield, Sales Director of Wallingford Software Ltd explained:.
"Pipes fail.
Some failures have a greater impact than others, in terms of the resulting number of customers without supply and the number of customers with unacceptable pressures.

SIAAP adopts InfoWorks CS for Wastewater Planning
SIAAP, a major French wastewater management organisation, has purchased InfoWorks CS, the leading software solution that integrates asset and business planning with urban drainage network modeling.
Examining these impacts for each asset identifies the critical links those with a high impact if there is a failure.
The risk associated with each pipe can then be calculated, with risk defined as the probability of failure multiplied by the impact of failure.
The probability can be inferred from data on the pipe condition and type that is stored in InfoWorks." InfoWorks has always enabled the estimation of the criticality of a single pipe by setting up a specific run of the model.
The new function automates this for every pipe in an input list provided by the user.
One by one these will be analysed by the model, simulating the effect of the failure of each pipe.
The tool will run an automated analysis report to evaluate the effects of link failures, offering both standard options and criticality options.
These will include a list of items such as links, analysis criteria, and Nodes to Ignore, burst duration and parameters.
The model is one step ahead of the traditional approach.
With breakdown occurrences you isolate the failure by closing the valves and by providing an alternative supply.
The operator would then assess the effect on a sample of customers with insufficient supply and investigate possible ground water intrusion.
The preventive approach (and more suited solution) of automatic criticality assessment is to use the model to identify 'critical' links, design a response strategy, test alternative solutions and ensure alternative supply.
Detailed analysis reports will be available showing local versus remote effects, residual pressure, duration, remote residual pressure, remote duration and maximum pressure.
Analysis into burst flow, pipe burst versus pipe failure, orifice at the end of the link, pressure related flow with explicit detail of burst size (based on a üstandardı leak) and burst duration will be accessible.
The Result Files will include added reporting files so that a file for each base model and each critical pipe will be obtainable.
Reports, (available in summary or detailed format) will include Standard, Simulation and Service level reports.
Paul Banfield concluded: "The launch of the new Critical Link Analysis tool will reap great benefits to modellers by helping them effortlessly identify ücriticalı links, devise response strategies, test other solutions and ensure alternative supply.
Now, the risk of unplanned interruptions can be ameliorated.
By applying the analytics and reports together with research, controlled contingency plans and preventative strategies can be successfully implemented.".
