EcoVault® Type II Baffle Box
Precast Stormwater Filtration System
The EcoVault® is a Type II Stormwater Treatment System which demonstrates exceptional nutrient removal efficiency.
EcoVaults® are designed and hydraulically checked for each installation; usually precast (concrete) and delivered completely assembled with the exception of very large units (which may be cast on site). As a standard, all internal components, debris screens, baffles, filters, spreaders etc. are stainless steel, PVC and concrete.
The Florida Department of Environmental Protection minimum standard for Type II Baffle Boxes is a load reduction effectiveness of 19.05% Total Nitrogen (TN) and 15.5% Total Phosphorus (TP). However, a 2014 independent study demonstrated that the EcoVault® easily exceeds the FDEP minimum standards, and outperforms competitors’ Gross Pollutant Separators (CDS Hydrodynamic Separator by Contech and Nutrient Separating Baffle Box by Suntree Technologies).
EcoVault® verified removal rates:
|
• Total Phosphorus: 57% • Fecal Coliform: 77% |
• Zinc: 79% • TSS: 91% |

The EcoVault® multi-stage filtration system provides separation, screening, and filtration
EcoVault® design features allow for a quicker settling velocity, ensuring maximum particulate capture.
The EcoVault® will remove coarse organic materials and debris, e.g. grass clippings, leaves, litter etc. and will trap and store them above the static water line, greatly reducing decomposition and nutrient leeching. Debris screens span the entire width of the EcoVault®, creating extensive storage volume, while allowing for continuous flow treatment. The EcoVault® will remove sediments, heavy metals, nitrogen, phosphorous, oil, and grease.

Internal Components
The Baffle Buddy™ Cassette Filter is a high flow filter integrated into the last baffle wall of the EcoVault®. It becomes the final internal weir.
To reduce maintenance costs, Baffle Buddy Cassette Filters are replaceable and contain the specific patented EcoSense filter medium; (NG-A, NG-B, NG-C, NG-Fe, etc.) for your EcoVault, and specific to the targeted contaminants you want captured.
Maintaining an EcoVault®
Servicing the EcoVault® is simple with unique accessible hatches, and requires a vacuum truck to remove the sediments, accumulated organic matter, and litter. This maintenance should be performed on a regular and, as-needed, basis (before, and following storm events, etc.), as well as before your filter replacement service.
Filter maintenance for the EcoVault® is simple. The addition of specially designed hatches makes them easily accessible for periodic inspections, vactor-truck service, or filter change(s). In order for the filter(s) to perform as designed, it is recommended they be replaced either annually, or semi-annually, depending on the local conditions, and as recommended by EcoSense. The cassette-style cartridges are recycled, inspected, cleaned, and refilled with the applicable media blend, reducing replacement costs. Quarterly inspection of the EcoVaults is recommended to ensure the debris screens are not getting clogged with larger organic matter, and the chambers are not filling up with sediment.
