Barhale’s United Utilities storm overflow scheme: design and risk notes for engineers
Reviewed by Joe Ashwell
First reported on New Civil Engineer
30 Second Briefing
Barhale has secured a United Utilities contract to deliver a storm overflow reduction scheme on Micker Brook at Bramhall, Stockport, aimed at improving downstream water quality. The project will focus on upgrading combined sewer overflow infrastructure and associated network assets to cut spill frequency and volume into the watercourse. Civil and geotechnical teams can expect significant works around live sewers and constrained urban corridors, with tighter spill consents likely to drive higher storage requirements and more complex hydraulic control structures.
Technical Brief
- Works are located at Bramhall, Stockport, implying tight interfaces with existing residential and local highway infrastructure.
- Delivery will require coordination with United Utilities’ operational teams to maintain service continuity during construction.
- Urban setting points to constrained laydown areas and likely phased traffic and pedestrian management arrangements.
Our Take
Barhale’s work for United Utilities in Stockport comes on the back of multiple recent water-utility wins in our database, including shaft and tunnel schemes for Severn Trent Water and Thames Water, signalling that it is consolidating a niche in complex underground water infrastructure across the UK.
The Bramhall detention shaft tank project mirrors Barhale’s June 2026 stormwater shaft scheme near Stoke-on-Trent for Severn Trent Water, suggesting the contractor is leveraging repeatable shaft-storage designs to meet tightening storm overflow and WINEP-style regulatory requirements.
Within our 923-piece Infrastructure corpus, Barhale now appears frequently in ‘Projects’ and ‘Contract Award’ items tied to major UK water companies, indicating that utilities such as United Utilities, Thames Water and Severn Trent are favouring established civils specialists for regulatory-driven resilience and overflow reduction programmes.
