FP McCann filter bed wall remediation for Notton Sewage Treatment Works

Posted: Monday 9th November 2015

The small Notton sewage treatment works is situated between Wakefield and Barnsley in West Yorkshire and is owned and operated by Yorkshire Water. Constructed over 40 years ago, the waste treatment works involved replacing two 13 metre filter beds with ageing and failing precast concrete walls.

Commenting on the project Paul Tower, Works Manager with Mott MacDonald Bentley said:
“The efficiency of installation of the precast concrete filter bed walls combined with the quality and durability of the factory prefabricated unit, gives us the confidence we are putting in place a system that will perform very well over its 40 year design life. The added assurance of the long-term guarantee, reinforces the commitment and resources that FP McCann has put into this product to ensure its future success.”

Engineering design consultants to Yorkshire Water, Mott MacDonald Bentley (MMB) set out the brief to extend the design life of the existing filter beds by a further 40 years and at the same time with both the beds, pipe work and filter arms in good working order, keeping the plant operational throughout the construction process. Re-cladding with a ‘jacket’ of precast concretewall panels was the chosen option and after a meeting to discuss initial proposals, FP McCann submitted structural designs and costings for the complete supply and installation package for approval.

FP McCann precast concrete filter bed panels are suitable for cladding around existing failing brick walls, precast concrete walls, in-situ cast concrete and natural stone walls. The precast filter bed panels are designed to accommodate handrail fixings to water industry specification.
