Which of the valves in your water supply network are critical, and would have the most impact if there were a network failure or other valve operations? The Criticality Assessment Manager app within InfoWater Pro works it out for you, enabling you to make the right financial and operational decisions.
A critical valve may only affect a small section of the network if it closes, but would impact a much wider area if it failed to shut when required, and additional valves in the wider network had to be shut instead. Pinpointing these valves requires a thorough understanding of the risk (probability and consequence) posed should the valve fail to shut. The impact is measured in terms of the numbers and types of customers and properties that would experience unacceptable levels of service (e.g. low pressure or loss of supply).
The software identifies and highlights the customers that would be affected and offers many display and reporting options.
You can also score asset criticality – the number of customers with poor service – by combining external GIS data (mainly valve layers) with modelling elements (such as pumps and pipes).
Reasons for failing to close a valve include lack of maintenance (e.g. a seized valve or broken motor), inaccessibility (e.g. in a busy highway or intersection) or unsuitability for manual operation (e.g. large diameter valve). By identifying critical valves, water utilities can effectively prioritize expenditure on solutions (e.g. maintenance, replacement, relocation, SCADA motorization or control).
A typical water utility may have thousands of line valves in its water supply and distribution system and assessing each valve individually may not be manageable. Criticality Assessment Manager in InfoWater Pro is designed to efficiently assess multiple valves in a network, enabling water utilities to accurately evaluate their entire water supply and distribution systems quickly and reliably.
