The problem

Wapro, in collaboration with their UK partner, Aquatic Control Engineering (ACE), engaged in detailed consultations with Halcrow and the Environment Agency to offer an alternative to the initial specifications for these pumping stations. While the original design proposed the use of stainless steel flap valves, which would necessitate regular maintenance and specialized lifting equipment for inspections and repairs, the collaborative discussions led to a shift in approach.

WaStop® Inline Check valve

Post-consultation, the decision was made to supply and design six WaStop inline non-return valves. These valves presented several advantages over the original concept: they required minimal maintenance, provided in-pipe protection for the membrane, and, crucially, were much easier to install. The design's inherent simplicity allowed Interserve to execute the construction without the presence of a dedicated Installation and Project management team, streamlining the process.

In terms of specifics, the Beam River pumping station was equipped with three NPS 56" WaStops, which, at the time of the project, were the largest WaStops ever manufactured. Meanwhile, Gores Brook saw the installation of three NPS 40" WaStops.

In reflection of this successful collaboration, ACE extends its gratitude to Halcrow, Interserve, and the Environment Agency. They appreciate the opportunity to contribute to this project and commend the professionalism displayed in the scheme's management from start to finish.
