Parkeston Pumping Station

Client: Environment Agency
Value: Variable

Jackson completed vital restoration works Parkeston Pumping station in north-east Essex as part of the Asset Refurbishment Programme of Works (APRoW) for the Environment Agency.

UV Lining Installation

In 2018, Jackson refurbished a series of structures conveying the River Ramsey below the railway which runs through Parkeston International Port to the Stour estuary.

The existing failed flap valves in the balancing chamber located on the north side of the railway have been replaced. Three further penstock valves have been replaced with flap valves in the Pumping Station located adjacent to the southern side of the railway. The project also involved the installation of UV lining to repair one of the failed culverts.

Weedscreen Replacement

In 2019, Jackson replaced the weedscreen at the lower end of the Ramsey/Dock River which also required piling to both river banks, new steel work and associated Reinforced Concrete pile caps and flood walls.

A new bypass over pumping pipework has been installed to enable dewatering in the event of an emergency if and when required.

The Dock River cannot naturally flow into the Stour estuary, all water, including flood water, must be pumped into the culverts beneath the railway into the tidal estuary. These pumps can hold a maximum of three cubic meters of water a second.

The new weedscreen works will provide a safer more effective means of clearing and maintaining the structure to prevent vegetation from blocking the pumps.

Jackson Site Agent, Lee Dunne said: “This scheme is a culmination of years of hard work and collaboration between Jackson and the Environment Agency under the ARPoW scheme.”

“Now complete, this will improve the functionality of the weed screen ensuring a safer means of maintenance of the pumping station for all Environment Agency operatives.”

“In turn the new emergency bypass pipework guarantees that the Environment Agency are able to dewater the channel in the event of a failure of the main pumps."

Throughout the project, the team worked inside a live port and working closely with port security to minimise disruption to port operations.
