Chertsey STW

Shay Murtagh recently partnered with Galliford Try to complete a critical project at Chertsey Sewage Treatment Works (STW) in Egham, North West of London. The project, commissioned by Thames Water, required the construction of a robust storm tank designed to manage excess water during storm events.

Our team undertook the installation of a 30-metre diameter in-situ reinforced concrete sloping base. This base was constructed with precision and expertise, involving a substantial volume of concrete to ensure a solid foundation for the storm tank.

Following the completion of the base, a 27.3-meter diameter and 7-meter high prestressed post-tensioned concrete tank was erected. This tank was specifically designed to accommodate large volumes of stormwater. One of the more complex tasks involved was the integration of large-diameter pipes, which were cast on-site to ensure an exact fit and seamless operation within the system. These critical connections were integral to the overall function of the storm tank, ensuring efficient water management during peak flows.

Throughout the project, quality and precision were key priorities. The construction was managed in collaboration with R. Betts Construction, a trusted long-term subcontractor, ensuring that every aspect of the work was completed to the highest standards. As with all our projects, we focused on delivering a solution that meets stringent environmental and quality requirements.
