Wastop installed in Thames Gateway

Environment Agency | Thames Gateway England | Flood protection

The problem

The Thames Gateway is an area of land in the southeast of England that stretches along the River Thames from the City of London eastwards through Thurrock and Bexley and on to Southend in Essex and Sheerness in Kent. Over the next 20 years, 120 000 new homes will be built and 180 000 new jobs will be created.

The Environment Agency has built two large pumping stations and refurbished a tidal sluice as part of ongoing works to alleviate flooding in the local area. These pumping stations provide a significant level of flood protection to large areas of Barking and Dagenham. Aquatic Control Engineering consulted closely with Halcrow and the Environment Agency to provide an alternative solution to the original specification for these pumping stations. The original concept outlined a stainless steel flap valve solution, requiring maintenance and lifting equipment for inspections and repairs.

Solution

WaStop^® Inline Check valve

After consultation it was decided to include six WaStop inline non-return valves into the project. These were not only cheaper than the external style valve, but they also offered lower maintenance, in-pipe protection for the membrane and, more importantly, easier installation.

Three of the WaStops that were installed in the Beam River pumping station – measuring 1400mm (NPS 54”) in diameter – were the largest to have been made at the time of project. The three WaStops at Gores Brook are 1000mm (NPS 42”) in diameter.
