Witches Hat Drain Guard

Protect water systems from sediment and pollutants with witches hat drain guard catch basin inserts
The witches hat drain guard is a stormwater management product — it prevents oil, grease, dirt, sediment and trash from stormwater entering drains. 70% of all storm drains lead directly to open waterways without treatment, so our drain guard is engineered to filter stormwater waste before it becomes a water system problem. Its geotextile fabric and easy installation make it ideal for industrial facilities, construction sites, and parking lots where stormwater runoff is likely to carry oil, eroded soil, debris, and fuel contaminants from cars.

Two product types:
1. Oil and sediment type — removes up to .87 gallons of hydrocarbons as well as dirt, sand, and other contaminants.
2. Trash and debris type — explicitly designed to catch larger items and floatables like leaves, cigarette butts, and paper goods.

Our witches hat drain guard exceeds 80% sediment removal efficiency, so it complies with NPDES, 40 CFR 122.26 (1999) when used as Best Management Practice in Stormwater Pollution Prevention Plans.

It is easily installed in most drains; raise the grate, place the witches hat drain guard over the opening, and carefully lower the grate back in place. As a final step, pinch the fabric in place to keep it secure.
