Plot Attenuation Systems

Our plot attenuation systems consist of multiple parts that come together to create an efficient water storage and discharge system that helps avoid flooding. The first component is a siltblok silt management system, which is designed to be installed upstream of a water storage or attenuation system, whether it be a water tank or a pond or a swale. Siltbloks will filter out any sediment in the water that passes through them.

This filtered water will then enter the second component of this system; the pelican attenuation tank, which is used to temporarily store water before it is discharged through either an oriflo or vortex flow control chamber in a controlled manner into a storm drain.

We offer plot attenuation systems with tank capacities from 2000 litres all the way up to 5500 litres.
