Maintenance

The StormChambers are designed with a defined top portal area at the “down-flow” end of the chamber which can be cut out to accept a riser pipe up to 10 inches in diameter. The riser can be used as an observation well and to allow a vacuum truck tube to remove sediment from the underlying patented “SedimenTrap”. The “down-flow” ends of the StormChambers have end walls which are closed on the bottom and function similar to a coffer dam, with most of the sediment depositing into the adjacent sediment trap prior to flowing into the next chamber. This facilitates its removal through the riser pipe located directly above. It is recommended that the sediment traps and clean-out risers, at a minimum, be placed at the first and last chamber of each row of StormChambers which receive the flow from the storm water inlet(s).

Sediment should be removed when deposits approach within six inches of the invert heights of connecting pipes between StormChamber rows, or in sumped inlet structures.  The needs of each site are different and so the necessary maintenance schedule will vary with each site.  To determine the best schedule the sediment traps should be inspected quarterly and after each major storm event.  It is recommended that a logbook be kept of each observation to determine the depth of the water in the StormChamber systems and how quickly the system is dewatered.  Once the performance characteristics are determined a monitory schedule can be created based on the unique needs of the individual site.  Research demonstrates that labor costs for cleaning one SedimenTrap with a vacuum truck is approximately $50.00.

The use of fully grated inlet structures will keep the vast majority of debris out of the StormChamber System. Inlet structures with a 2-4 foot sump are recommended. This will allow for additional capture of sediment that can easily be removed with a vacuum truck or other device before it gets into the StormChamber system. The addition of a Snout, by BMP Inc., or similar structure over the outflow into the StormChamber system will retain flow tables within the inlet structure.

It is highly recommended that the StormChamber system not be opened to receive storm water flows until construction of the site has been completed. Even then, all storm water inlets must be protected from sediment loading until the site is completely stabilized. Complete stabilization implies that the construction site has been cleared of construction-related debris and has incurred at least two storm events sufficient to wash most soil and other particulate matter off impervious surfaces.

Testimonial

  • “Because we have installed several StormChamber systems, a lot of engineers have asked for advice on competing plastic chambers. We have always recommended the StormChambers. They far exceed the competition on cost and ease and speed of installation.”

    Dean Clark General Manager, SECO, LLC, Chelton, WA

  • “Much less expensive and much quicker and easier to install than the 64″ pipe originally speced for the project.”

    Joe Szabo Owner, J&R underground contractors, Milan, MI

  • “Significantly faster and easier to install than pipe. Significantly less staging room needed and a lot fewer trucks to receive and unload.” (The equivalent of 213 LF of pipe nest on one pallet, 1,913 LF on one truck.)

    Bob Dawson Owner, Dawson Company, Woodbridge, VA

  • “We have installed several StormChamber systems because we find them to be a lot less expensive and quicker to install than the competing systems and we can install them in two layers on very confined sites.”

    Ed Shaw Shaw Construction, Reno, NV

  • “We were surprised by the ease of use of the system and greatly appreciated support provided. We are already looking forward to building our next StormChamber project!”

    Erik Gervais PE, Constructions GFL, Brossard, QC

  • The Loudon One project in Ashburn, VA

    “I also like that it can be cleaned by air vacuuming via inspection /cleanout ports instead of using water. Anytime you have to clean something with water, then you have to have a truck that collects the water and the sediments in it. Depending on where you can dump that, it can get much more costly as opposed to going out with a vacuum truck.”

    Steve Pandish Director of Water Resources for the engineering firm of William H. Gordon Associates in Chantilly, Virginia

  • HUGO SIMS METAL RECYCLING FACILITY IN THE BRONX, NY

    “The choice of StormChambers met the design requirements for strength in such a way that the chambers could be stacked three deep with 30 feet of cover, if needed. Strong enough to sustain the impact of 18-wheelers loaded with steel. They also were 30 percent more cost-effective than other options.”

    Dr. Paul Mankiewicz hydrologist and consultant to the City of New York on storm water and related issues and executive director of the not-for-profit Gaia Institute in the Bronx, NY

  • Double-stacked system in Tukwilla, WA

    “It was easy. There were no difficulties once the owner decided on the StormChamber system. The project is holding up to heavy traffic, pump tracks, and cranes.”

    Tom Radice Abbot Construction

  • Charles-Lemoyne Hospital, Greenfield Park, Quebec

    "We were amazed by the simplicity of this system and have appreciated the support from the Soleno team during the entire project. We are already looking forward to designing another project using the StormChamber!"

    Érik Gervais, P. Eng Const. GFL, Brossard, Quebec
