Rain Activ

Rain Activ is an award winning SuDS system especially developed to provide highly effective, lower cost, storm attenuation for domestic properties.

The system acts as a buffer during intense storm events. Collecting rainfall from the roof the releasing it into the drainage system at a controlled rate, helping reduce surface water flooding issues.

Rainwater is filtered heavily using a low maintenance, self cleaning filter, then diverted into an underground tank. At a calibrated position within the tank, the water is released though a discharge orifice; Thus meeting a ‘discharge rate’ stipulated by planning authorities.


Uniquely, Rain Activ can combine SuDS with rainwater harvesting- providing a dual benefit to the homeowner.
