Questions about Attenuation and Stormwater Systems

What is an attenuation system and why is it important for commercial developments?

An attenuation system controls surface water runoff, storing excess rainwater and releasing it slowly to prevent flooding on and around commercial developments.

Do you design and install attenuation tanks for new build construction projects?

Yes, Edenway Contractors provides bespoke design and installation of attenuation tanks and sustainable drainage systems (SuDS) for new build projects.

What are sustainable drainage systems (SuDS) and how do they help manage surface water?

SuDS are engineered drainage solutions that manage rainfall and runoff by mimicking natural water processes, supporting flood prevention and planning compliance.

Can Edenway Contractors install attenuation and stormwater systems as part of a complete groundworks package?

Absolutely. We integrate attenuation and stormwater management systems into our full groundworks and civil engineering packages for smooth project delivery.

What types of developments require attenuation and stormwater management systems?

Commercial, residential, infrastructure, education, and healthcare developments all require stormwater management to meet planning and environmental regulations.

How do attenuation systems help reduce the risk of flooding on construction sites?

Attenuation tanks capture and store rainwater, releasing it gradually to local sewers or watercourses, minimising flood risk during heavy rainfall events.

Do you install underground attenuation tanks, soakaways and flow control systems?

Yes, we specialise in installing underground attenuation tanks, soakaways, flow control devices, and SuDS for both commercial and residential schemes.

How do you ensure attenuation and stormwater systems comply with UK drainage regulations and planning requirements?

We design systems in line with UK drainage regulations, SuDS guidance, and local authority planning requirements, supporting compliance documentation on all projects.
