The Boat Houses, Christchurch Meadows Oxford
This contract was to install a new wastewater drainage system on the boat house island in Christchurch Meadows. Due to the nature of the ground make up and the proximity of the river Thames and Cherwell it was always going to be an interesting job. There were several challenges to overcome the first being to move the plant onto the island.

This was a deep system and at its lowest point was approaching 3 meters. Pumps were used constantly to control the ground water throughout the works and earth supports to retain ground stability and allow access. Due to the height and pressure of the ground water, precast chambers were used rather than a more traditional construction to ensure the system remained sealed.
