Our design of the Maida Vale Flood Alleviation Scheme has eliminated sewer flooding to almost 200 properties

The Maida Vale area was served by three Bazalgette, sewers all about two metres in diameter and built in the late 19th century. However, these sewers did not have the capacity to transfer additional flows brought about by increased permeable areas and changes in climate. This resulted in extensive flooding to properties in the surrounding urban areas during severe storm events. Due to the sheer density of the urban area and the limited available space to build, part of the solution required flows to drop 13 metres into a tunnel and storage facility. To achieve this, a vortex type control structure was required to ensure flow could be safely and efficiently dropped to a low level.

Acting as design partner, we undertook this project as part of a joint venture with contractors Murphy, Barhale, and Clancy Docwra on behalf of Thames Water by Optimise. A demanding timescale was a vital consideration for our team. Key tasks were run in parallel, including the hydraulic modelling and detailed design. This ensured that we and our Optimise partners had sufficient time to undertake the construction. As all construction work was carried out within an extremely busy urban environment, risk to the public was given great consideration and noise impact was kept to a minimum.

Our solution required separation of the flooding area from the sewer network. We achieved this by transferring flows to a 20-metre diameter, 26-metre deep storage shaft which pumps stormflows back into to the receiving sewers, when conditions allow. This has also been achieved through extensive hydraulic modelling to aid the development of a means of allowing the base / foul flow to remain connected to the existing sewer network, whilst ensuring that there is no risk of storm flows from the existing system causing flooding.

The Maida Vale Flood Alleviation Scheme was awarded the Keep the Public Fully Informed (Communication) Award by the National Joint Utilities group.
