Cartridge Vaults To Be Installed In RI
A cartridge vault system planned by John Rocchio Corporation of Smithfield, RI. They will be installing a 40 cartridge vaults known as StormSafe™ Treatment System manufactured by FABCO Industries, Inc., in the Town of Marion, MA. The installation is part of a 10 year, multi-phase infrastructure improvement project that is projected to cost the town $5.2 million. The project is taking aim at replacing outdated and deteriorating sewer pipes, drainage systems, roadways, and sidewalks that not only are an eye sore, but also have been the cause of some environmental issues. As a result of these problems, namely the sewer pipes and drainage systems, there is an abundance of polluted stormwater being discharged into the local harbor.

FABCO worked with the Town Engineer, CDM Smith of Providence, RI to determine the most effective means of stormwater filtration for the storm sewer shed of Ryder Lane. Relative to other filtering systems, the StormSafe™ cartridge vault is designed to provide a highly effective treatment solution within a small footprint, which matches the needs presented by the Town Engineer as they worked with predetermined space limitations.
By utilizing the same proven filter technology as the StormBasin™ product line, a Massachusetts Stormwater Technology Evaluation Project (MaSTEP) listed technology; the StormSafe™ cartridge vaults can reduce concentrations of targeted stormwater pollutants, and allows for flexibility in design. Both of these factors being of utmost importance to this project solidified the decision to include StormSafe™ within the project specifications. Additionally, commitment to long-term success was shown within the specifications that resulted in the FABCO supplying 3-years’ worth of cartridges to the Town of Marion Department of Public Works for the cartridge vaults.

StormFilter is a passive, flowthrough storm water filtration system. It consists of rechargeable media cartridges housed in a concrete vault. The vault is composed of three bays: a pretreatment bay, a filter bay, and an outlet bay. Heavy solids are removed at the pretreatment bay. Flow then passes through the media filled cartridges that trap particulates and adsorb dissolved materials such as metals, hydrocarbons, and orthophosphate. Treated water empties into an underdrain manifold that discharges to the outlet bay.
Application: The StormFilter is a self contained, underground vault system appropriate for treating runoff from parking lots, industrial sites, and roadways. The design is well suited for areas where space is limited and treatment needs are high. Advantages: · Various media – Seven different types of media are available for the filter cartridges. Of particular interest is an iron infused media capable of removing dissolved phosphorus. Pleated fabric and perlite are reportedly effective for removing fine sediments. Other media are well suited for removing hydrocarbons and soluble metals. ·
Flexible configurations – StormFilters are available as pre-cast vaults, cast-inplace units, and pre-cast filters designed to be installed in storm drain drop inlets. Cast-in-place units can be quite large, involving over 100 individual filter cartridges. Drop inlet units are designed to handle small flows at individual locations with one cartridge per unit.
· High pollutant removal capacity – StormFilter media cartridges appear to be effective for removing dissolved pollutants and fine sediments. Independent studies suggest high dissolved phosphorus removal rates associated with the iron infused media. · Pretreatment may be required to remove coarse sediment to prevent clogging of cartridges. Disadvantages: · Yearly maintenance may be time consuming and expensive.
Each cartridge weighs roughly 150 pounds and must be replaced at least once per year. · Smaller StormFilters (such as the drop inlet units) may not be capable of filtering high flows. · Caltrans reports unfavorable performance in Southern California.
