The projects have been awarded under Thames Water’s £200 million+ AMP8 framework for Major Projects for Developer Services and Infrastructure Programmes.

The framework is chiefly focused on the provision of infrastructure services required to meet the needs of third parties, such as developers, and covers a range of larger-scale, more complex work including diversions, requisitions and lateral drains.

Adjacent to the Peel Centre at Rushgrove Park, Brent Cross, Barhale will design and construct a new offline foul storage attenuation system. It will comprise a diversion from the existing foul sewer, a 560m3 shaft tank to provide additional storage and to intercept flows from a CSO spilling into the water course and a pumped return to an existing manhole.

The works form part of the London Borough of Barnet’s proposed upgrades to Rushgrove Park which include improvements to the tennis courts.

To serve new housing development and to upgrade capacity for existing residents at Benson north of Wallingford in Oxfordshire, Barhale will build and commission a new 500m foul gravity sewer and 15 new manholes. The new sewer will shorten the route of the existing network and improve resilience.

At South Basingstoke, Hampshire, Barhale will construct a new sewer (590m) and associated manholes at Winchester Road. At Kempshott Lane it will increase the capacity of an existing sewer (484m) and upgrade the existing manholes. The works will accommodate connections to new housing developments. Design work is being carried out by Barhale’s specialist design business, ESL.

Florin Edu, Barhale’s Contract Manager, explained that Barhale was working closely with Thames Water to ensure the successful delivery of all three projects.

“These are important schemes which are either meeting or anticipating growth at each location,” he said. “They are also providing a substantial benefit to existing residents and businesses by increasing network resilience and increasing the network’s ability to cope with increasingly extreme weather conditions.”
