The drainpac is a multi-layer filtration insert.  The filtration liner is comprised of a non-woven filter cloth which has been tested and proven to maximize filtration of sludges containing heavy metals and petroleum hydrocarbons,  The insert support grating is comprised of a high-density polymer rated at 7,500 pounds per foot.  The insert support grating and filter are suspended below the drain, thus eliminating any interference with traffic flow.

The DrainPac is a catchment and filtration system for any storm drain system. The retrofit design allows for simple installation and maintenance to any catch basin.

Composed of a flexible storm drain catchment and filtration liner it is designed to contain contaminants and debris prior to discharge into storm drain systems. In laboratory tests conducted by the University California Los Angeles (UCLA), the DrainPac reduced petroleum hydrocarbons and heavy metals to non-detect levels.

There are three parts to the DrainPac:

Metal Support Bracket. The bracket is a metal bar with holes and studs. The holes on the bracket are used to retrofit to any structure. The studs on the bracket support the basket and the liner.

Insert Support Basket. The basket is comprised of a high-density polymer grating rated at 7,540 lbs. per foot. The bottom of the support has a criss-cross configuration that multiplies the ultimate strength value. The basket is supported by the studs on the bracket.

Filter Liner The liner is comprised of non-woven polyropylene. The liner absorbs hydrocarbons and catches contaminated suspended solids. The liner has retainer rings that are supported by the bracket.

The insert support grating and filter liner are suspended below the drain, thus eliminating any interference with traffic flow. The DrainPac system will conform to all sizes, shapes and configurations of storm drains. The only modification is to install a support bracket to the interior drain structure and insert the DrainPac.

The DrainPac system is a cost effective method to reduce pollutants to the EPA's "Maximum Extent Practical." and is a Best Management Practice to assist in complying with NPDES and Clean Water requirements.
