Rainwater Soakaway Systems

Traditional rubble-filled soakaways, with typically only a 30% void ratio, accommodate ground water until it can soak away into the surrounding permeable ground. Modern soakaway structures have a significantly greater storage ratio of around 95% which gives flexibility in design, either a reduction in excavation and ultimate reduction in cost or by maintaining the same size soakaway, providing greater storage capacity.

The Building Regulations (Part H) now state that whenever possible soakaway or infiltration should be the method for discharging stormwater. This is further endorsed by The Environment Agency and SEPA; both of whom are committed to this highly effective source control technique.
