With increased production of surfaces impermeable to water in construction, including buildings, car parks, loading bays and road pavements, the natural drainage process is altered and increased stormwater runoff in respect of both volume and flow-rate is required.

In many cases this increase in volume is not a problem as the local sewer will have a sufficient capacity.

However in many situations the local network is running full and would be adversely effected by any increase in flow or volume. These problems can be removed by an increase in the size of the stormwater sewer or watercourse, in the form of a Tri-Cel Attenuation system.

The Tri-Cel Attenuation Systems offers a complete solution to your the stormwater attenuation requirements and utilises a tried and tested method of attenuation. KMG are able to provide a complete package of design, specification, and supply of Tri-Cel attenuation systems.
