REM Weighted Walnut Wattle –  The Weighted Walnut Wattle™ provides homeowners, commercial property owners, municipal employees and construction personnel with a method of significantly reducing urban water runoff pollution.  The Walnut Wattles™ can be placed and physically configured at key locations throughout a site, with the intent of capturing/filtering the water that runs off your project. Typically, the filters are placed at the point on your site where water runs off into the street or into a storm drain.  The filters are flexible and will conform to almost any landscape geometry and can be configured in multiple shapes including U shapes and circles.
