The Water Decontaminator catch basin insert filter system is available in a sealed housing with drain valve. In sites where there is a possibility of a hazardous material spill these filters will contain 100% of the spilled material. Valve can be opened during rain events for filtered flow. Water passes trough standard Water Decontaminator filters before draining into storm drain. An unfiltered overflow valve is included for high flow rain events.

• Contains hazardous material spills in an easy to clean stainless steel housing.
• Pre-valve filters remove suspended solids, heavy metal, oils and other contaminants from stormwater runoff.
• Secondary unfiltered overflow valve for high flow rain events.
• Valve can be adjusted to increase settling time and maximize filtration.
• Sampling port built into filter cap allows for taking effluent stormwater samples.
