Wyke Gardens Dual Manhole Study

Through their expert tunnelling experience and customer care, the Barhale team at Wyke Gardens, Ealing, were able to greatly reduce long standing flooding in to the River Brent, whilst maintaining traffic flows and customer relations in a densely populated area of west London. The Wyke Gardens storm water network in west London had a history of regular flooding and discharges into the River Brent. These discharges were polluted with foul water flows from 40-50 illegal or misconnections to the storm water network.

Barhale was selected by Thames Water to:

Construct a new CSO chamber and online storage tank to reduce the discharge events and provide a new static screen to remove the solids from any overflows.

The works were based in and around the busy A406 (North Circular Road), leading to and from the Hanger Lane Gyratory System – one of the busiest junctions in London, which incorporates 10,000 vehicles an hour.
