An innovative solution adds water quality to every HydroChain storage system
The Filterow is a water-quality component that captures pollutants with filtration in a designated section of a HydroChain storage system. This innovative water-quality component isolates pollutants from the primary storage system and keeps pollutants from compromising the efficacy of the entire system.
Typically installed at each inlet, the Filterow allows treated stormwater to flow into the rest of the storage system without the need for a manifold and eliminates the need to clean out individual storage rows.
The Filterow can be installed as a standalone stormwater treatment component, or as part of a larger treatment train solution.
Material
Fiberglass reinforced composite
Approvals
NJCAT technology verified
Virginia DEQ approved
TSS Removal Efficiency
85.1% cumulative TSS removal
Flow Rate
Proven top-performance pollutant removal
Whether the main storage system is constructed of chambers, vaults or crates, the Filterow is NJCAT-verified for more than 85% removal of total suspended solids (verified to the 2021 NJCAT filter protocol). It is also verified for phosphorous removal up to 40%.
Designed and engineered for maximum flexibility
- Designed to reduce maintenance costs
- Engineered to maximize storage system life
- Simplifies installation integrated internal bypass manifold
- Reduces footprint by removing the need for external piped manifold
- Can be ordered precut for faster installation
- Can be cut on-site for flexibility with pipe connections (up to 12 inches)
With main storage rows of chambers, vaults or Aquamod – a Filterow can be made of any of these chamber models

A simple way to increase the system’s treatment flow rate and filtration area is to expand the Filterow footprint.
Easy inspection and maintenance
After an initial inspection to verify the system is functioning as designed, the system should also be inspected immediately after the first major rainfall or storm event. The schedule for ongoing inspection and maintenance is based on the following factors:
- Storage system size
- Site and environmental conditions
- Drainage area
- Annual rainfall
- Volume of stormwater runoff
- Volume of sediment, dirt, debris and trash
Here's how
- Inspect the Filterow by accessing the inspection ports and adjacent structures to measure the depth of captured sediment
- If the depth of sediment has met the limit outlined in the Filterow O&M Manual, perform maintenance per those instructions
- Use an adjacent structure to access the Filterow with a high-pressure sprayer and vacuum
- Use the sprayer to flush the sediment and debris towards the vacuum
Note: For full instructions see the Filterow O&M Manual.
