The water industry regulator Ofwat, challenged the industry to reduce the average number of supply interruption minutes per customer to just 3 minutes per annum at the start of the current AMP. The consequence of this measure has seen water companies investing in enhanced pressure monitoring, network resilience schemes and improved processes for managing supply interruptions.
Ofwat have clearly laid out their guidelines for what constitutes a reportable customer in these instances; but are your post-event reporting processes aligning to these guidelines? It only takes 1 large burst event to exceed the 3-minute threshold, leading to costly ODI penalties for the water company.

Quantitative, repeatable process
Hydraulic network modelling is the key to accurately reporting the average supply interruption minutes for each event, offering a quantitative, repeatable process that provides an evidence based, auditable methodology.
HydroCo have developed a bespoke tool to measure reportable supply interruption minutes, which has proven to significantly reduce supply interruption minutes over more traditional methodologies, resulting in more accurate reporting and reduced ODI penalties.
