The Drain Warden with Gutter Guard installs internally into the stormwater outlet with the benefit of being unobtrusive for vehicles and pedestrian traffic. Water entering the drain passes through a geotextile filter combined with a highly absorbent hydrophobic polypropylene sock. Whilst silt, trash and debris are captured in the filter, hydrocarbons, oils and fuels are absorbed in the suspended sock. The Gutter Guard attached to the Drain Warden, blocks excess water from the drains curb side opening preventing further debris from entering. In situations of excessive waterfall, the Drain Wardens built in overflow features prevents water backing up.
