Project Description

Why did the client need our services?

The client was experiencing repeated issues with the existing treatment plant being overwhelmed due to the high water table. They were also struggling with compliance on the treatment plant, partly due to this issue and partly due to the pollution of foul waste with grease from the busy pub nearby using the facility for their wastewater treatment.

Working alongside an independent wastewater consultant, a system was designed to allow the volume and condition of the waste entering the treatment works to be controlled using above ground storage tanks and a new pumping station.


National Trust


Bodiam Castle, East Sussex

Work carried out

Installation of new GRP pump chamber

What challenges were faced?

Bodiam Castle is an area of historic interest, so an archeological dig was carried out during the excavation for the pumping station to check for any items of interest.

The high water table in this location required constant groundwater management through diesel overpumping during the excavation work.

The castle is also a live public site so public safety had to be carefully managed. We were also aware that the storage tanks could overwhelm the new pumping station in the event of a failure as they would continue to fill, so a high level alarm was installed as a build specification in the control panel.

What work was carried out?

Willow Pumps carried out all the necessary civils work for this job, and then successfully installed the new GRP pump chamber with two above ground 10 metre3 storage tanks, all associated drainage changes and the installation of a passive below ground grease trap.
