Attenuation Tank Installation: Reducing Risk with Wavin StormForce

Written by Wavin UK | Nov 13, 2025 11:23:08 AM

As climate change intensifies and urbanisation expands, the pressure on surface water infrastructure continues to grow. Flooding is no longer a rare occurrence—it’s a recurring challenge for developers, contractors, and local authorities. One of the most effective solutions to mitigate this risk is the installation of attenuation tanks, which temporarily store excess stormwater and release it at a controlled rate. But successful attenuation tank installation requires more than just the right products—it demands expert design, seamless logistics, and guaranteed compliance. That’s where Wavin StormForce comes in. 

Why Attenuation Tanks Matter 

Attenuation tanks are a cornerstone of Sustainable Urban Drainage Systems (SuDS). These underground structures help manage stormwater runoff by holding water during peak rainfall and gradually releasing it into the drainage system. This prevents flash flooding, reduces pressure on sewers, and supports environmental sustainability. 

Wavin’s AquaCell attenuation tanks are modular, scalable, and designed for fast, efficient installation. Whether used in residential developments, commercial sites, or infrastructure projects, AquaCell units offer high load capacities and flexible configurations to suit a wide range of applications.  

Common Risks in Stormwater Projects 

Despite their benefits, stormwater projects often face significant risks: 

  • Delays in installation due to poor planning or product availability 
  • Non-compliance with evolving legislation and local authority requirements 
  • Cost overruns from unexpected site challenges 
  • Performance issues from incorrect design or installation 

According to Wavin’s guide on reducing risk in stormwater projects, these challenges can be mitigated through early engagement, expert design, and a clear understanding of regulatory frameworks such as the Flood and Water Management Act 2010 and Ofwat’s Sewage Sector Guidance

Real-World Success: Hatfield Station & Lingfield Gardens 

StormForce has already proven its value in high-profile projects across the UK. At Hatfield Station, one of the busiest commuter hubs, Wavin delivered a bespoke attenuation solution to manage surface water from a new multi-storey car park. The StormForce team handled everything—from design to installation—ensuring minimal disruption and maximum flood resilience. Read the case study  

Similarly, at Lingfield Gardens, Wavin collaborated with Obsidian Homes and CB3 Consult to install a 395m³ attenuation tank that met Welsh Water’s strict requirements. The project involved just-in-time delivery, structural and hydraulic calculations, and a full turnkey service—all managed by StormForce. Read the case study
