Our range of attenuation systems

We offer a full range of sizes for storm crate systems and attenuation tanks. We can custom build your attenuation tanks or storm crates to equate for the amount of water you produce.

Our stormwater solutions enable you to manage stormwater rather than causing flooding downstream. Our compliant stormwater attenuation systems will release the water back into the environment safely, preventing flooding and pollutants entering the waterways.

What is stormwater attenuation?

Stormwater attenuation is a solution used to control flooding and prevent pollutants from entering our waterways.

This is done by taking the rainwater and holding it in a stormwater attenuation tank system and then releasing it at a rate that does not inundate the water system and cause flooding.

Stormwater attenuation is the storage of stormwater for a period of time, and then release it back into a watercourse or sewer network.
