Galliford Try has teamed up with Siemens to accelerate the integration of digital technologies across the lifecycle of water and wastewater projects.

The new model brings together the companies’ complementary solutions and expertise in the water sector to help water companies meet the regulatory, environmental and operational pressures in modernising their infrastructure while reducing time, cost, risk and carbon.

The joint digital tools and sector experience will help water companies solve a range of challenges, such as the ability to identify potential blockages in sewer networks, improve operational efficiency of treatment works and become a net zero industry by 2030.


Due to the early collaboration between Siemens and Galliford Try in advance of future projects, the partnership is estimated to speed up delivery of new tech enabled infrastructure developments significantly.

The partnership will focus on three use cases. Firstly, it will enable optimisation of the wastewater treatment process using mechanistic digital twin technology. The solution optimises energy by up to 20%. It operates in real-time with integration of the control system, or offline and the solution can be offered to support a specific project or offered as a service integrated with sensor and model management.

The second use case reduces storm overflows and pollution incidents. The end-to-end solution, from sensor installation to an application, uses artificial intelligence (AI) to find nine in 10 blockages and automates reporting of overflows in real-time. This is coupled with the opportunity for a UK company to be the first to deploy a proven solution, already operational globally, for catchment level integrated control that reduces overflow volumes from existing infrastructure by 80% in light rain and 19% in heavy rain.

The third use case focuses on reducing the risk and maintenance of sewage pumping stations. This retrofit solution for pumping stations reduces pump blockages by 80% and improves pump performance and risk.
