Black & Veatch is to work up plans for a huge flood defence scheme for Berkshire and South West London.
The firm will carry out the appraisal study for the River Thames Scheme, which would protect 15,000 properties, mainly between Datchet and Teddington.
Plans for a £300M scheme in this region were unveiled by the Environment Agency in 2009. The area suffered heavy flooding in 2003 and again last winter.
The latest appraisal study will see GBV – a joint venture of construction firm Galliford Try and consultant Black & Veatch – assess feasibility, undertake outline design and create a business case.
If it goes ahead, the scheme will see creation of a flood channel running parallel to the River Thames between Windsor and Shepperton.
The capacity of the weirs at Sunbury, Molesey and Teddington will be increased; and the Desborough Cut widened.
“To facilitate this we will be undertaking outline design, and a diverse range of environmental, geotechnical, hydraulic and economic assessments; drawing upon experience gained on the Jubilee River, Olympic Park, and Thames Tideway projects,” said GBV director Matthew Nott.
