Major remodelling and extensions to a 1930’s built college to increase pupil capacity to 1100.

A major challenge at the site was the lack of availability of storm water sewers near the site and an existing foul water drainage network that had been extended at various times. Design checks showed that the exiting main foul drains under the building were running in excess of design capacity, leading to significant risk of blocking and surcharging.

Careful assessment of foul drainage flows and diversion of parts of the existing network allowed us to allow for the additional discharge from the extensions whilst reducing design flows in the foul drains to more acceptable levels.

The lack of storm water sewers and nearby watercourses, along with a very high water table required careful consideration of storm water disposal. Shallow drainage infiltration blankets were adopted which included overflow systems to distribute surface water run-off to areas of the site where infiltration was more effective.
