£2M Bedfordshire storm tank upgrade: design and performance notes for engineers
Reviewed by Tom Sullivan
First reported on New Civil Engineer
30 Second Briefing
A £2M upgrade to increase storm storage capacity at Anglian Water’s Poppy Hill Water Recycling Centre in Bedfordshire is nearing completion, aimed at holding larger storm inflows before treatment. The project focuses on expanding storm tank capacity to reduce combined sewer overflows to local watercourses during intense rainfall events, in line with tighter UK water quality and discharge consents. Civil and geotechnical teams will be watching performance under first major storm events to assess tank hydraulics, settlement behaviour and inlet/outlet structure resilience.
Technical Brief
- Construction sequencing must manage differential settlement risks between new tank foundations and existing process structures.
- Commissioning strategy should include live storm event proving tests on inlet screens, weirs and overflow structures.
- Updated operating procedures and confined-space permits will be required for inspection and maintenance of enlarged storm facilities.
- Similar UK WRC upgrades are increasingly driven by tighter storm overflow obligations under revised environmental permits.
Our Take
In our database, Anglian Water features in multiple recent stormwater and storage schemes in eastern England, signalling a coordinated programme of smaller (£2–3M) and larger (£18M+) upgrades rather than isolated interventions.
The Bedfordshire works at Poppy Hill Water Recycling Centre sit alongside Anglian Water’s larger Walton-on-the-Naze storm tank project, suggesting the operator is standardising storm storage enhancements across both coastal and inland catchments to manage extreme rainfall and overflow risk.
With 918 Infrastructure stories and 2,492 tag-matched pieces on projects and safety, Anglian Water’s repeat appearance underscores how UK water utilities are currently among the most active infrastructure clients in our coverage, particularly for resilience and compliance-driven upgrades.
