OVERVIEW

Background

Black & Veatch was appointed by United Utilities to deliver a major upgrade of the ageing Oldham Wastewater Treatment Works (WwTW). As part of the wider scheme, full treatment operations at Royton WwTW were to be discontinued, with flows transferred to Oldham WwTW, where new secondary and tertiary treatment facilities were being developed to accommodate the increased capacity.

JK Fabrications Ltd was engaged by Black & Veatch to undertake the refurbishment of the existing Primary Settlement Tank facilities, providing a modern and reliable solution to replace ageing infrastructure that had been in service for over two decades.

Scope of Works

Decommissioning and disposal of six existing rectangular scraper bridges
Detailed design and engineering of six bespoke rectangular scraper bridges
Manufacture of six 15-metre rectangular scraper bridge systems
Supply and installation of associated weir plates
Fabrication and installation of associated pipework

Site installation and mechanical assembly
Testing and commissioning of all equipment
Operational performance verification

Outcome

The project was successfully completed in 2017 as part of the wider multi-million-pound upgrade of Oldham WwTW.

JK Fabrications safely decommissioned and removed the six existing scraper bridges before designing, manufacturing, installing, and commissioning six new bespoke 15-metre rectangular scraper bridge systems. The upgraded equipment has improved the reliability and performance of the Primary Settlement Tank facilities, supporting the increased treatment demands resulting from the transfer of flows from Royton WwTW.

The successful delivery of this project demonstrates JK Fabrications’ expertise in the refurbishment and replacement of critical wastewater treatment infrastructure, delivering complex mechanical solutions safely, efficiently, and to the highest quality standards within live operational environments.
