Whiston Lane in Knowsley has been subject to a major flood event in December 2017 caused by intense/prolonged rainfall. Investigations were carried out and further monitoring was needed.
A number of properties at Whiston Lane in Knowsley have been subject to internal flooding during periods of intense/prolonged rainfall. This has been a problem for some years and without changes, this was set to continue costing potentially thousands & thousands. Also, the emotional turmoil the residents were enduring each time it rained needed to be addressed.
KaarbonTech, in conjunction with Tarmac, supplied and installed 6 Gully Sensors and 2 Culvert Sensors in Knowsley.
A new land drainage system has recently been installed alongside extensive re-modelling/landscaping work which will help to prevent the potential reoccurrence of a flooding incident. We were keen to add extra resilience and saw the installation of gully sensors as an effective way of complementing the works previously completed.
The water level information from the sensors ensured that when a further severe weather event in June 2019 occurred the event was successfully managed proactively (rather than reactively) and a potential flooding situation was prevented.
The sensors proved invaluable during the recent spell of wet weather as we were able to continuously remotely monitor the water levels in the culvert and gullies.
Using remote intelligence, we were able to instruct proactive gully cleansing at the optimum time during the wet weather period and also visited the site to reassure residents and provide floodsax. As an additional precaution the sensors are linked to Tarmac’s out-of-hours emergency response system and are set to send an alert to the Duty Manager should water levels rise to a critical level.
Having all this data is incredible. Gully and culvert alarms notify us of dangerously high water levels."
