Founded upon 52 years of operating experience, EPS Group has grown from an electrical and pumping services business in to an innovative, internationally exporting group, headquartered in Mallow, Co. Cork and focused upon the water and wastewater and clean technology sectors.
Coppermills Water Treatment Works is located in north London adjacent to the Walthamstow Wetlands, a 300-acre reservoir system providing approximately one third of London’s drinking water.
Challenges to the supply of water from Coppermills were identified by Thames Water with effective capacity being reduced during periods of algal bloom. These periods of bloom placed an increased workload on the existing 24 rapid gravity filters within the treatment works, which in turn could restrict output to 380Mld, limiting headroom in the London supply demand balance.
As a solution it was decided to build an additional 12 rapid gravity filters to augment the existing infrastructural capacity on site. The overall project was co-ordinated by SMB as part of the eight2o delivery alliance and collaboration was supported by EPS/MWH through their MEPS JV.
EPS Group undertook the concept design, design and off-site construction of 12 filter flumes in stainless steel to provide 200MLD capacity, using an off-site ethos to maximum effect while massively reducing health and safety risks when compared with traditional construction methods.
This 18-month programme of work and off-site ethos saved £6 million in preliminaries, in addition to a 40% reduction in carbon. A total of 3,400 tonnes of pre-cast concrete was installed in 18 weeks; with zero temporary works or formwork and zero accidents on site.
