Anglian framework win for Systra: hydrological design lessons for infrastructure teams

30 Second Briefing
Anglian Water has appointed Systra Limited to its hydrological surveys and assessments framework to support capital delivery and environmental programmes across infrastructure schemes in the East of England. Systra will deliver baseline hydrological surveys, flood risk assessment and modelling, impact assessments and post-construction monitoring to inform planning, permitting, detailed design and construction sequencing. The work will influence drainage strategies, flood resilience measures and hydraulic design parameters for new and upgraded assets across Anglian’s network.
Technical Brief
- Hydrological deliverables will directly condition hydraulic structure sizing, freeboard allowances and overland flow routing.
- Flood risk modelling outputs are expected to feed into sequential test arguments for planning approvals.
- Post-construction monitoring will allow calibration of design rainfall–runoff assumptions against observed asset performance.
- Cross-sector experience from transport schemes suggests use of multi-source data: gauging stations, LiDAR and radar rainfall.
- Safety and sustainability are explicitly stated as core design drivers, influencing option selection and construction sequencing.
Our Take
Anglian Water’s recent moves – from the @one Alliance ramp-up and mains renewal push to the Samotics monitoring extension – suggest that Systra Limited’s framework win plugs into a rapidly scaling AMP8/AMP9 delivery machine in the East of England, with strong demand for design and systems integration skills.
With Gleeds already appointed on Anglian Water’s client-side commercial assurance framework, Systra’s role points to a more segmented supply chain where technical, commercial and digital assurance functions are split across specialists rather than bundled into single large programme partners.
Within our 915-item Infrastructure corpus, Anglian Water now appears in several closely spaced pieces, signalling that it is one of the more active UK utilities in letting new frameworks and upgrades, which may set reference standards for sustainability-led procurement in other UK regions.
