Amey is installing sensors into gullies in a new trial designed to see if they can prevent road flooding.
The trial is taking place in Hampshire and aims to give councils and contractors real-time information on when a gully is getting blocked, as opposed to inspections on a timetabled basis.
Silt levels and water levels inside the gullies are measured and this is fed back to a control centre via web-based software. The information is visually displayed on a map. Based on this information, a gully cleanse can be organised before it floods, thereby avoiding an emergency cleanse. It also means money could be saved as gullies are only cleansed when they are at risk of flooding.
“This is exciting, new technology which should enable us to be much more proactive in terms of preventing gullies becoming flooded, as opposed to dealing with the issue in just a reactive way. We have installed 25 sensors in known ‘high risk’ gullies and are currently collecting information at these sites,” said Amey account director Paul Anderson.
“If these sensors works as well as we hope they will, then it could lead to a radically different approach in Hampshire and elsewhere.”
