Soakaway
A pit excavated in the garden and filled with rubble or a proprietary plastic crate system, designed to receive surface water or rainwater discharge and allow it to percolate gradually into the surrounding ground. Soakaways must be located at least 5 m from any building to avoid undermining foundations and sited where the soil has sufficient permeability. A percolation test should be carried out before relying on a soakaway.
