A Morgan Sindall/Grontmij joint venture (MGJV), has been awarded a circa £26M project from Yorkshire Water Services to improve Scarborough’s bathing water quality.
The project involves the construction of additional storm water storage facilities at Wheatcroft Sewage Pumping Station as well as a new 25m diameter, 35m deep storage shaft at Toll House Pumping Station. The MGJV team will also construct diversion and reconnection tunnels between the existing sewer, Toll House pumping station and a new Combined Sewer Overflow (CSO).
In addition, a new CSO will be built at the Corner Café site whilst the existing pumping station at Scalby Mills pre-treatment facility will be extended and major pumps added. These will discharge into a new 800mm diameter rising main which will be laid for 2km over farmland up to the existing Scarborough Waste Water Treatment Works where the team will construct three new settlement tanks and an ultra violet treatment facility. The treated discharge will then pass through a further 2km of new 900mm diameter pipe to the existing sea outfall.
The completed project will improve the quality of the water which is discharged into the sea during storms.
The Scarborough project has been awarded as part of the AMP5 Yorkshire Water Framework, to which Morgan Sindall and Grontmij were appointed in August 2010. Projects under this framework range in value from £5M to £50M and include clean water and waste water projects from feasibility through design and construction to commissioning and handover.
