Slashing refurbishment time • Fabricating weir gates in-house proved a bonus when it came to saving time and minimising disturbance on a refurbishment scheme at Cookham Weir slashing installation times onsite. Installation of the gates required a section of the weir complex to be drained before work could begin. Once the weir gate sections had been isolated, ECS was able to install the new gates with min- imal fuss due to the exact fit of the gates within the existing structure. This minimised dis- turbance on the watercourse and to the surrounding envi- ronment, a key proviso for the Environment Agency. The highly oxygenated water at Cookham Lock also makes it a hotspot for fish, with everything from pike to barbel utilising this stretch of river. To improve safe fish migration, ECS designed and installed two Larinier fish pass channels in redundant gate bays to allow the movement of fish up and downstream. Fish are channelled into a 'ladder' which incorporates 'rungs' that the fish can move through, with each rung offer- ing fish a chance to rest before tackling the next section. The whole project ensured minimal disruption to the environment whilst improving the natural fish population. Jamie Wesley, contracts manager at ECS, says: "Our expertise and experience working with the Environment Agency means we take on these projects with the utmost confidence. Our comprehen- sive fabrications workshop ensures we not only protect ONSITE REFURBISHMENT ECS was able to install the new gates with minimal fuss due to the exact fit of the gates within the existing structure. The ten new weir gates form part of a larger project replacing ageing assets along the River Thames the environment during the project, but also provide a reli- able cutting-edge solution for the end user." ECS has more than 20 years' experience in delivering relia- ble and cost-effective engineer- ing solutions, specialising in bespoke design and construc- tion of water, energy and envi- ronmental processing and management projects. In conjunction with key supply partners, It has the expertise and capacity to design and install a wide range of water control engineering projects. With in-house fabri- cation services, which have CE Marking approval to EXC3, well equipped and highly skilled engineers can also complete structural steelwork, bespoke fabrication work and access metalwork to the highest standard.

The Nottingham- shire-based fabrication and water control specialist was contacted by Jackson Civil Engi- neers, working for the Environ- ment Agency (EA) to replace ten weir gates and install two fish passes at Cookham Weir, ensur- ing the continued reliable con- trol of water levels at the tourist hotspot for years to come. Cookham Lock denotes where the River Thames meets Chiltern chalk at Cliveden Cliff, where the surrounding woods and picturesque landscape attract anglers, walkers, river travellers and bird watchers from across the country. Due to the sensitivity of the area, ECS was first choice due to its focus on completing pro- jects quickly and in an envi- ronmentally sensitive manner, minimising disruption onsite. The new weir gates form part of a larger project replac- ing ageing assets as part of the EA's continued investment in water control facilities along this stretch of the River Thames. ECS designed, manufac- tured and installed all the equipment for this project including a significant drives and controls upgrade. It car- ried out the work in-house at its dedicated fabrications cen- tre, allowing the gates to be delivered in ready assembled, ECS Engineering Services designed, manufactured and installed all the equipment for this project including a significant drives and controls upgrade.
