Attenuation Tanks Frequently Asked Questions

What is an attenuation tank and why is it important?

An attenuation tank temporarily stores excess rainwater or stormwater to control runoff and prevent flooding. It helps protect property foundations, reduces surface water pressure on drainage systems and supports compliance with building and environmental regulations.

When do I need an attenuation tank installed?

You’ll need an attenuation tank if your site struggles with drainage or is at risk of flooding. They’re often required for new builds, extensions and commercial developments to manage stormwater effectively and meet planning or building control requirements.

How does an attenuation tank work?

During heavy rainfall, the tank collects excess surface water, holding it temporarily and releasing it slowly into the drainage system. This reduces flood risk, protects your property’s foundations and helps maintain local water balance.

What types of attenuation tanks do Basetec install?

We install a wide range of systems, including underground attenuation tanks, modular systems for larger sites and both plastic and concrete tanks. We also design and install custom-engineered tanks for complex or bespoke drainage projects.

How long does attenuation tank installation take?

Most installations can be completed within a few days, depending on the tank size and site conditions. We handle every stage from site survey and excavation to drainage connection and reinstatement.

Can attenuation tanks be integrated with existing drainage systems?

Yes. Our engineers design each system to connect seamlessly with existing drains, gullies and soakaways, ensuring efficient flow and compliance with Sustainable Urban Drainage Systems (SuDS) standards.

What are the benefits of installing an attenuation tank?

Attenuation tanks reduce flood risk, protect surrounding land and structures from water damage and provide a low-maintenance, long-term drainage solution that supports both regulatory compliance and environmental protection.

Where does Basetec offer attenuation tank installation?
