DrainPac™ Storm Drain Filter Inserts

United Storm Water's DrainPac™ is a storm water treatment control BMP product that captures and treats urban runoff before it enters the storm drain system. This #1 rated BMP product is capable of retaining 97% of total suspended solids and effectively prevents litter, debris, heavy metals and petroleum hydrocarbons from entering the storm drain system.

DrainPacs™ are custom-made at United's fabrication facility to accommodate any drain size or configuration in a manner that will not interfere with lateral line storm water flow. The experience that United has established in the field of storm water management is always capable of developing the unique solutions that our customers need. United offers a complete service package from fabrication and installation to inspections, cleaning and reporting that helps customers to comply with the Clean Water Act and associated storm water regulations.
