Residents of Reading can now sleep easier in times of heavy weather, following construction of a storm tank to help to minimise flood risk.

A huge new circular reinforced concrete slab (pictured) has been installed to complete the tank at Chapel Hill in the district of Tilehurst, to prevent storm surges from overburdening the sewer network.

The slab measures 9.5m in diameter and weighs 100t. It was designed and manufactured by Buchan Concrete Solutions at a cost of £28,000 at the Midlands factory of Roger Bullivant Ltd, the parent company of Buchan. This is the biggest such slab ever to be constructed at RBLís manufacturing facility in Burton upon Trent.

The slab was manufactured in six sections to make transportation easier, and assembled on site. It is supported by the storm tankís precast concrete walls, constructed with segmental rings that extend to a depth of 17m below ground level. Openings in the slab allow operatives to gain access and for equipment to be installed. Completion of the tank will be followed by construction of a concrete roadway on top.

Manufacture of the concrete slab took around two weeks and was completed on behalf of Delta Civil Engineering, a subcontractor to Morrison Construction which works on behalf of Thames Water Utilities.
