The work will improve phosphorous removal and flow monitoring to meet water industry national environment programme (WINEP) targets for England.

It forms part of Yorkshire Water’s £500m investment in Phosphorous removal – part of its ongoing commitment to ensure future facilities meet current and anticipated water quality targets.

Central to the scheme is the transformation of the primary treatment capabilities through the replacement of several of the 14 existing primary settlement tanks, with three new, larger tanks and two new primary sludge pumping stations.

The project will take advantage of off-site manufacturing to pre-cast the concrete wall sections before they are assembled on site to form the new 8.5m deep, 45m diameter settlement tanks.

An existing beck will be diverted to make way for the construction of the tanks.

Mark Wood, Barhale’s regional director for Yorkshire and North East England, said: “Effective management of phosphorous levels can make a big difference to the quality of water in our rivers and streams.”

Steve Milling, BarhaleEnpure JV Framework Manager said: “The award of this design and construct contract follows a prolonged Early Contractor Involvement phase of more than two years. Through this period, the BarhaleEnpure JV design team worked closely with Yorkshire Water and Stantec to refine the outline design and introduce significant value engineering changes.

“We look forward to delivering a cost-efficient plant design which, when commissioned, will be well able to meet the new Phosphorus standard.”
