Benchmarking by our solutions team, highlighted that water consumption stretching back for 15 years was far higher than it should be and justified on-site audits to get to the route of the problem.
The initial site surveys led to the adoption of further sub-metering and the introduction of PIR motion sensors to control flushing which contributed to an initial consumption reduction of 18%.
Having accounted for all the internal use, the team undertook a supply tracing exercise, that was further complicated by the absence of water services plans. The latest technology of online leak detection microphones was used on the underground pipes, to ensure that the site could continue to operate normally whilst the survey work was undertaken. Further leaks were identified and led to the installation of isolation valves to section out the site’s underground pipework and cap a section of unused pipework.
For a different property, an on-site assessment of over 750 metres of underground piping identified the need for the installation of meter isolation valves to measure the consumption for which the property owner and their tenants were each responsible and also identified underground leakage that was in need of urgent repair.
All in all, a holistic approach to yield reduced costs, lower consumption and improving the related carbon footprint
