Culvert cleaning schemes reduce the risk of flooding

Mackley Winchester Culvert

Mackley is currently working in the Hampshire city of Winchester, where it is carrying out CCTV surveys on a network of culverts across the city, to reduce the risk of flooding.

Once works are complete in Winchester, the project team will move on to Emsworth and Havant to carry out similar works.

The Winchester scheme, part of the Environment Agency’s PDU2 programme, involves first surveying the culverts and then either cleaning, repairing or replacing any that are no longer fit for purpose.

Culverts allow water to flow under a road, railway track or similar obstruction – and blockages can result in flooding.

The Mackley team has set up a compound in a council operated car park and has been liaising with Winchester City Council to arrange a temporary closure of a number of parking bays to give access to manholes for jetting and CCTV surveys.

The council has also assisted with a road closure and provided a temporary route through a car park to enable local residents to access their homes.

Some of the work is taking place on sacred ground at Winchester Cathedral, and the adjacent Pilgrims’ School which is associated with the Cathedral. While cleaning a culvert located within the school grounds, the team came across a WWII rifle (pictured above).

When the works are complete in Winchester, the team will move on to the nearby town of Emsworth to survey a section of culvert with a confined space entry, and then carry out any works that are required.

Following that the team will relocate to Havant to clean out a section of culvert and then carry out repairs to the culvert roof where it has started to collapse.
