Surface water drains normally discharge to a watercourse or indirectly into underground waters (groundwater) via a soak-away. Contamination of surface water by oil, chemicals or suspended solids can cause these discharges to have a serious impact on the receiving water.

Oil separators are therefore installed on surface water drainage systems to protect receiving waters from pollution by oil, which may be present due to minor leaks from vehicles and plant, from accidental spillage or due to deliberate and illegal tipping into drains.

SDS offers a broad range of Separators to meet the specific requirements of each site.
