Chopper pumps used in Thames Water¡¯s ¡Ì410m sewer upgrade project
As part of Thames Water¡¯s sewer upgrade project, the utility used Vaughan Chopper pumps to cope with increase capacity at the treatment works.
The utility is increasing sewer capacity at its Beckton and Crossness sites in East London to cope with a predicted population incase of 10% by 2021.
The projects, valued at ¡Ì190 million for Beckton and ¡Ì220 million for Crossness, will boost the site¡¯s treatment capacity by 44%.
The aim is to also reduce the volume of storm sewage that often overflows into the Thames water course during and after heavy storm events.
A key part of both projects involves the extraction of biogas from the organic waste within the sewage processed at both sites.
Extraction of the gas is performed by 12 anaerobic digesters across the two sites and each digester uses a pair of Vaughan HE6W10-277 Horizontal Chopper Pumps driven by 30kw/4 pole WEG motors, selected and supplied by P&M Pumps.
The WEG motors include ATEX conforming EExd ratings.
Matt Harvey, director at P&M Pumps, said: ¡°This application is extremely demanding as the load on the chopper pumps can be exacerbated by the substantial debris that can sometimes reach the pumps in spite of the upstream filters.¡±
