Project: Woolston Sewage Treatment Works Upgrade
Client: 4Delivery
Site Owner: Southern Water
Contract Value: £4 Million
Contract Term: 36 Months

Woodhams are proud to be part of the engineering team building the new sewage treatment plant in Woolston, Southampton. We have provided the mechanical design, manufacture and installation of the Primary and Secondary Works packages – from initial conception until completion.

The package included installing pumps, pipework and mechanical ancillary to provide a temporary treatment facility whilst phased demolition took place. We were then contracted to manufacture and build the primary process works for the new sewage treatment plant alongside the temporary works to ensure no treatment downtime. steel-structure-sewage-plant-installation

One of the main difficulties was site access and storage. Woodhams solved this issue by setting up a local off-site facility to assemble and manufacture bespoke mechanical items e.g. pump skids, steel structures, stainless steel distribution chambers and stainless steel pipework.

This facility allowed Woodhams to pre-assemble and transport the majority of the installation to site, giving us flexibility to provide a ‘just in time’ capability. This increased efficiency and decreased waste by receiving goods only as they were needed in the production process, thereby reducing costs.

Programme dates have continuously changed throughout the duration of works, which has meant we have had to be flexible and proactive as an organisation to ensure we limit costs on any delays or disruptions to our works. At Woodhams, we believe communication is key, which is why we ensure we hold weekly meetings, both internally and externally, and ensure we keep our clients updated with regular written and verbal communication.

We are proud to have received excellent feedback from our client, 4Delivery, which confirms our commitment to project management, health and safety and quality control.
