Product Benefits

StormChamber™ was designed as an open bottom, high-density polyethylene infiltration chamber BMP which functions in both permeable and non-permeable soils for subsurface retention or detention of storm water runoff and for a water quality BMP. StormChamber™ provides approximately 60% greater storage capacity than similar plastic storm water chambers. It reduces nutrient and other pollutant loadings by taking advantage of the natural biological and physical properties of the soil, directly comparable to the functions of a septic drain field. It also recharges ground water drinking supplies, while concurrently helping to maintain base flow to streams, wetlands, lakes, and ponds, and counter salt-water intrusion.

The StormChamber™ storm water management system provides an environmentally progressive and technologically advanced storage and pollutant removal solution that is more cost-effective and requires less maintenance than other types of underground storm water management systems.

StormChamber™ was developed by biologists, ecologists, and engineers to improve upon older plastic storm water chambers that have been used in the marketplace for over 10 years. StormChamber™ utilizes the same basic corrugated arch shape for structural integrity and exceeds the AASHTO H20 wheel load rating by over two times. StormChamber™ significantly exceeds the storage capacity of existing plastic chambers by over 60%, resulting in a need for fewer chambers, less stone, less filter fabric, less excavation, and approximately 50% less time to install. The side portal feeds eliminate the need for expensive header pipe systems currently used to manifold storm water effluent into rows of chamber systems. The ability to access any StormChamber™ in a system through the side portal feeds also provides great flexibility in engineering and hydraulic design, eliminating circuitous routing of feed pipes from storm water inlet structures to the entry point of a header pipe.

The combined designs of the side portal feeds and the slotted end walls with the provision for a 10" riser located near the "down stream" end wall facilitates sediment maintenance and removal. The open bottom of the StormChamber™ provides maximum infiltrative surface area, unlike the holes of a perforated pipe that easily become clogged. The open infiltration surface area functions similar to a septic drain field for nitrogen, phosphorous and other pollutant degradation with formation of a bio-mat of micro-organisms upon the underlying stone and soil. Pollutants are further degraded as they pass through the soil column. The infiltration of storm water also helps to replicate pre-construction hydrology as it recharges groundwater supplies, maintaining base flow to streams and wetlands and in coastal areas, helping to retard salt water intrusion.

StormChamber™ systems are not limited to areas with pervious soils. In non-pervious areas underground storage can also be provided with regulated outflow. Under these conditions, water quality is still enhanced more than with a pond due to the remediating effect of the bio-mat. Elimination of a pond also leaves land available for other uses.

StormChambers™ may also be used in place of concrete, corrugated metal, or HDPE pipe for storm water conveyance. They are less expensive, quicker and easier to install, and can be inserted directly into a storm water inlet structure, similar to pipe. Significant water quality enhancement over pipe is also achieved, with the associated infiltration benefits. When used in place of pipe for conveyance to ponds, algal blooms are minimized, sediment loading and maintenance is decreased, and pond level fluctuations are minimized by maintaining base flow. The StormChamber™ has a storm water conveyance capacity comparable to a 48" diameter pipe. Conveyance occurs through the StormChambers™ as well as the surrounding stone.
