ODA Primary Sewer and Pumping Station

Delivering an iconic pumping station as part of the Olympic development site. Barhale was awarded a £21 million contract by the ODA, to design and construct a primary foul sewer and pumping station, as part of the Olympic Park development.

The Primary Foul Drainage is a park wide utility which collects, conveys and discharges flows from the main venues, buildings and residential developments during the Olympic, Transformation and Legacy Modes. The system receives flows from the secondary foul drainage system and conveys flows by gravity to a terminal pumping station which discharges to the Thames Water Northern Outfall Sewer.

This highly complex, multi-disciplinary scheme included the construction of 2km of deep sewer in tunnel, 13 No. shafts ranging in size from 4.5m to 12.5m diameter and a large pumping station which formed the centre-piece of the contract.
