Stormwater/Erosion Control

Drain Donut

• Designed for filtration on catch basin grates
• Equipped with a flood level by pass, which allows water to overflow directly into the basin
• Compressible foam rubber donut
• For filtration the filter uses high flow - non woven polypropylene. This allows storm water to pass through the filter to enter the catch basin during normal flow levels
• The filter enwraps the basin grate completely blocking unfiltered water

The DRAIN DONUT is designed for filtration on catch basin grates. It is equipped with a tlood level by pass, which allows water to overflow directly into the basin. The filter poses little danger to traffic because the by pass wall is a compressible foam rubber donut. For filtration the filter uses high flow -non woven polypropylene. This fabric allows storm water to pass through while holding back silt and sediment. Storm water must pass through..the filter to enter the catch basin during normal flow levels. The filter enwraps the basin grate completely blocking unfiltered water.

Installation:
To install, pull the basin grate and wrap the edges of the filter around the grate rim. Then tie the edges in place by pullingthe cord through brass grommets. Drop the filter and grate back into the basin as one unit. For the ultimate catch basin protection use the DRAIN DONUT in combination with the BASIN BAG.
