More effective leak detection
Previously, Tønder Water Utility only had the numbers from the pumping station to go on. If the total volume of water sent to Rømø was high compared to their experience and the historic data from the SRO system, it might indicate a leak. To localise it, the utility had to manually read and exclude one street at a time during night time, when it would cause least inconvenience. Today, the quantity that is pumped is compared automatically to the consumption in each district, making it easy to categorise the actual loss.
“With District Analyser, we go directly to leakage localisation. Before, two men could spend nine nights to track down a leak, with another week for preparatory work. Today, we can do it all in two or three days. There is a lot to save in terms of time and money,” says John Pies Christiansen. “It is about discovering where we can act most effectively – and that requires data. Driving around looking for a half cubic metre is like looking for a needle in a haystack. And it’s no good to just send in the whole cavalry.”
“With the overview we have today, we can also identify rising tendencies and be proactive,” explains Christian Møller. Among other things, this means that the supply company has improved the service it offers its customers. “Now that we have both data and knowledge, we also feel like we have a responsibility to use it to help our customers.”
