Construction Stormwater Products
                        "Stormwater Compliance Made Easy"

Sedi-Sock Dewatering Filter

Picture
The Sedi-Sock Dewatering Filter is an environmentally friendly option to help achieve regulatory compliance with water quality discharge standards. Effectively de-water sediments and fine particulates down to 100-microns while achieving excellent flow rates in excess of 150-gpm. Huge cost savings compared to vacuuming, transporting and off-site waste for disposal.

Applications:
  • Fire Sprinkler System/Utility Box dewatering
  • Trench/Ditch Excavation Area dewatering
  • Tank/Sump & Containment dewatering
  • Process Water Filtration for Reuse
  • Filtration of Water from Pressure Washing Operations

Catch Basin Sediment Filters

Picture
Adjustable frame Catch basin Sediment Filters to meet your construction Temporary Erosion Sediment Control (TESC) BMP Requirements. Adjusts from 12"x12" up to 30"x30" catch basin grate sizes to meet your NPDES construction permit requirements

This catch basin sediment filter is made from a hi-strength geotextile fabric material that captures sediments, debris and gross solids, and is cleanable and re-usable and has 2 ports for adequate overflow protection.




Round Catch Basin Sediment Filters

Picture


Round Adjustable Catch Basin Sediment Filters for your round catch basins or dry wells. Filters sediments, solids and debris from surface water impacts. Adjusts from 18" to 36" diameter.

Has adequate overflow protection when the filter becomes full and comes with heavy-duty nylon lifting straps for easy removal. Meets EPA  utility drainage, as well as Temporary Erosion Control and TESC BMP Requirements.




ADSORB-it External Catch Basin Filter Berms

Picture
The ADSORB-it external catch basin filter berm is a flexible collar for fitting around grated inlet catch basins that prevents the direct mobilization of heavy sediments and works with your catch basin sediment/debris filter helping them to last longer and achieve below benchmark testing levels.

The external Catch Basin Filter Berms come in 4' and 6' standard lengths and with either a 4" or 6" tall boom, as well as longer custom lengths for larger type catch basin structures are available.  Additional protection can be achieved by adding adsorbent filter media contained within the filter berm to provide the treatment of fine particulates, total suspended solids (TSS) and metals such as zinc, copper and lead from polluted storm/surface water runoff.

Construction Debris CB Filters

Picture
The Construction Debris Catch Basin Filter has been designed as a large debris filter keeping heavy sediments and objects from entering storm drainage structures. Ideal for use at construction sites, heavy vegetative and landscape areas.

Made from a hi-flow geotextile fabric material wrapped around and reinforced by heavy-duty wire mesh on the inside, allows the flow of rainwater through the fabric while keeping sediments and debris from entering your drainage structure.

Can be adjusted to fit around all sizes of grated inlet drains and catch basins and can be washed and re-used many times over.

ADSORB-it Contour Ditch Booms

Picture
The ADSORB-it Contour Ditch Boom & Bio-Swale Filter is ideal for use at construction sites in small drainage ditches, swales, channels, culverts and spillways to prevent the mobilization of sediments and debris from impacting off-site and protecting water quality.

The ADSORB-it fabric allows the unrestricted flow of storm and surface water through the filter while trapping oils, sediments, suspended solids and debris.

The ADSORB-it Contour Ditch Boom has a 3" floatation boom across the top with a ballast chain on the bottom to allow it to conform to the shape of the ditch or waterway. The ADSORB-it fabric material is cleanable and reusable material that can be washed and used again many times over.
