Interceptors and risers are not designed to withstand water table height in excess of the top of the unit when buried. If there is a possibility that ground water will come into contact with a grease interceptor or solids interceptor, the unit must be installed with an anti-flotation anchor kit. At risk areas include but are not limited to tidal surge areas, floodplains and areas that receive storm water. Features: Four polypropylene sling style tie-down straps Two aluminum anchor plates (hold-down force achieved by backfill weight)
