IN Brief:
- Kier has secured two further early contractor involvement commissions under Southern Water’s AMP8 delivery framework.
- The awards cover resilience and nitrate-removal schemes at Hastings, Brede, Beauport, and Brighton East.
- The appointments take Kier’s potential Southern Water construction workload to more than £480m.
Kier has strengthened its water-sector pipeline with two further early contractor involvement commissions under Southern Water’s AMP8 Strategic Delivery Partner framework.
The latest Stage 1 appointments cover the Hastings Resilience programme and the Brighton East nitrate removal scheme. Together, they add further development work to a pipeline that now includes 31 ECI projects for Southern Water, with a combined development-phase value of £104m and expected construction value of more than £480m.
Under the Hastings Resilience programme, Kier will help develop upgrades to treatment processes and water supply resilience across the local network. Work at Brede Water Supply Works includes improvements to rapid gravity filters, high-lift pumping stations, clear water tanks, disinfection systems, and discharge infrastructure, with additional resilience works planned at Beauport Water Supply Works.
At Brighton East Water Supply Works, the scope centres on nitrate removal through new treatment facilities, network reconfiguration, and raw water transfer improvements serving Brighton East and Falmer. The works sit within a wider investment programme shaped by water quality, resilience, environmental performance, and population growth across Southern Water’s operating area.
Across the water sector, AMP8 is moving from regulatory settlement into detailed programme formation, with utilities under pressure to deliver larger capital programmes while maintaining live asset performance. Treatment works upgrades, network reinforcement, nutrient management, leakage reduction, and resilience schemes are all feeding demand for civil engineering, mechanical and electrical work, process equipment, controls, commissioning, and specialist subcontract capacity.
Early contractor involvement has become a more prominent feature of this market because many schemes cannot be treated as isolated construction packages. Water infrastructure work often takes place on constrained operational sites, where temporary works, shutdown windows, process continuity, access, and commissioning strategy need to be understood before designs are locked down. Earlier contractor input can reduce redesign, improve buildability, and give clients a clearer view of programme and cost exposure before main works begin.
For Southern Water, the framework gives access to contractors capable of shaping projects before delivery risk becomes embedded. For Kier, the awards add depth to an infrastructure business already active across regulated sectors, transport, utilities, and public works. Major programme and cost-management activity has also remained active across the wider built environment, with recent growth across major project advisory work underlining how much of the market is being driven by long-duration infrastructure and capital programmes rather than short-cycle building demand.
The practical construction challenge will be delivery discipline. Utilities are being asked to move faster, improve environmental outcomes, and respond to public and regulatory scrutiny, while contractors continue to manage labour constraints, specialist equipment demand, and inflation risk. On live water assets, programme certainty depends on sequencing, access planning, supplier coordination, and a strong commissioning route, not just headline framework capacity.
As AMP8 gathers pace, the strongest opportunities will sit with contractors and suppliers able to combine design input with reliable site execution. Kier’s latest Southern Water awards show how the next wave of regulated infrastructure work is being shaped before it reaches site, with development-phase appointments now defining the construction opportunities that will follow.
