Hampton and Kempton Water Treatment Works (WTW) are key Thames Water sites for the supply of potable water to London residences. Both sites were without a permanent recirculation system for bed conditioning of their slow sand filters (SSF); the beds are currently drained using mobile diesel pumps and flexible hoses. Installation of a permanent recirculation system provided significant technical challenges for acceptable pump operation, particularly in achieving suitable pump inlet conditions due to the limited space available for the pump installation and the flow rates required.
Bedford Pumps secured both contracts with Thames Water by providing industry leading technical support and guidance on the design of the pump inlet chambers, which enabled suitable inlet flow conditions for stable pump operation to be achieved. A canister, specially designed by Bedford Pumps, plus a unique benching arrangement from hydraulic model testing consultants, Hydrotec Ltd, was key to the success of this project.
Bedford Pumps are to supply 16 dedicated WRAS/DWI approved vertically mounted submersible canister pumpsets, to provide a permanent water recirculation system for the SSF beds at Hampton and Kempton WTW.
Bedford Pumps are delighted to be working once again with Thames Water to satisfy their pumping requirements.
