A soakaway is an underground system that allows surface water to drain safely into the ground. New housing and commercial developments in Wiltshire and Hampshire often require soakaway systems, and under the Flood and Water Management Act, shared soakaways must meet adoptable standards.
In the past, soakaways were often poorly designed by builders or contractors using rubble-filled pits. Today, professional design is essential to ensure compliance, reduce the risk of flooding and deliver a system suited to site conditions.
