The Water Business Unit provides strategic support across the clean water network, covering both system performance and infrastructure planning. We assess the future hydraulic state of the network in response to population growth and increased demand, support the design and delivery of capital and infrastructure schemes to ensure hydraulic resilience, and work with optimisation teams to enhance overall network efficiency.

Water Recycling (East and West)
Our Water Recycling Business Unit, split into East and West regions, is responsible for the collection, conveyance, and treatment of wastewater across an extensive network. We operate over 76,000 km of sewerage infrastructure and 1,163 treatment centres, ensuring safe and sustainable discharge to the environment while driving innovation and environmental performance.
