Prevent rainwater from carrying trash, debris, and sediment into sewers. These filters are often used on construction sites. They mount inside curb openings, keeping them out of the way of vehicles. Push the foam anchors into a curb opening to hold them securely in place, even during heavy rainstorms. Connect them side by side or cut them to length to fit any drain width.

Reduce lead, zinc, mercury, and other heavy metals in wastewater and storm water while letting water flow through. Shape these flexible sorbents around drain grates and storm drains. The woven polyethylene covering is UV- and puncture-resistant, so they hold up well outdoors and on rough surfaces such as pavement.
