Type II Baffle Box

Precast Stormwater Filtration System

  Download the brochure

The EcoVault® is a Type II Stormwater Treatment System which demonstrates exceptional nutrient removal efficiency and is 3rd party verified to outperform competitors.

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:

 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 may 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.

The EcoVault® Baffle Box Construction

Structure Typically precast, though it may be cast in place, the EcoVault® is constructed of reinforced concrete to provide strength and durability. Its multi-piece construction minimizes shipping and lifting requirements, and features a slab top. Access hatches and an H-20 Load rating are standard features.

Internal Components The EcoVault® features cast-integrated concrete baffles and may contain full-width debris screens. Debris screens are expanded stainless steel with a heavy frame and hatches for full sump access. The elevation of debris screens may be adjusted in the field, a self-adjusting system is available. 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. NutriGone™-C is the standard filter media for the Baffle Buddy™ Cassette Filters. Other media such as Poseidon Pellets are also available to target specific contaminants, such as phosphorus. The filters are typically replaced annually, but may require more frequent changes depending on conditions. Used filters are removed, emptied, cleaned, repaired, and reloaded. This service is available with EcoSense International.

Maintaining an EcoVault®

EcoVault® Baffle Boxes collect large amounts of sediment and debris and require a dedicated maintenance program. This service will require a vacuum truck to remove sediments, accumulated organic matter, and litter. Routine maintenance should be performed quarterly, however, additional maintenance may be required after major storm events.

EcoVault® Sizing

Sizing may vary depending of the specific site conditions and requirements. Custom sizes can be designed.
