Premier Inn Heathrow T4, Drainage Design
This 160m-long box culvert was designed to act as a foul water storage tank with restricted discharge to the public sewer. Taylor & Boyd’s design of the storage system included hydraulic modelling.
The culvert is fed by a 550m rising main from Crowne Plaza Hotel and a 250m rising main from Premier Inn Hotel, both on the Heathrow site.
Working to precise airport standards the rising main was directionally drilled beneath the A30 carriageway.
The box culvert’s internal diameter is 1.5 x 3.0m. It was constructed in reinforced concrete.
Taylor & Boyd’s engineers worked in close liaison with Thames Water to procure an Impact Study, plus adoption and connection approvals. We supervised the on-site construction, and inspected quality of construction against design.View More Projects
