Critical mains analysis offers a method for gauging the significance of a pipe within the water network. The scoring criteria are founded on the consequences of a pipe failure, taking into account the number of customers affected by isolation and those experiencing low pressure.
Risk & Impact
System Resilience
Prioritise Investment
Minimise Supply Interruptions
Typically, the analysis is conducted twice: first, to evaluate the short-term repercussions of a failure, and the second assessment aims to comprehend the medium to long-term resilience of the system through rezoning. Additional weighting may be applied to pipes with subpar resilience.
Recent advancements in modelling software allow water companies to swiftly determine the importance of each pipe using network models. This capability empowers water companies to prioritize mains laying or rehabilitation projects, optimise their capital spending budgets, and minimise the impact of failures on customers.
