Place Based Thinking

The Place Based Thinking team delivers some of the largest and most complex projects across the @one Alliance. Made up of six Senior Project Manager teams, we oversee 19 catchments, covering key sites such as Whitlingham, Flag Fen, Great Billing, Cotton Valley, Bedford, Colchester, and Ipswich Cliff Quays. These projects involve managing all parts of the network from rising and gravity mains, pumping stations, high spilling overflows, and water recycling centres.

Water

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.
