18 in. High StormChamber® Systems

Capture large volumes of stormwater runoff with a smaller footprint than traditional underground systems with the StormChamber® system. 18 in. high arched modular stormwater chambers can be laid out in unique configurations to fit job site requirements, and stacked to increase storage capacity while maintaining usable space above ground.

Key Features

Holds significant volume compared to other same size stormwater chambers on the market
Minimum installed storage for start unit 48 cu.ft., middle unit 43 cu.ft., end unit 48 cu.ft., closed unit 70 cu.ft.
Internal chamber volume start unit 24 cu.ft 24 cu.ft., middle unit 23 cu.ft., end unit 24 cu.ft., closed unit 25 cu.ft.
Designed for strength due to thermoformed high-density weight polyethylene (HMWPE) material; withstands extreme environments, and exceeds the AASHTO H-20 design load
Simple install - internal crossover eliminates expensive header pipe manifold system; modular chambers overlap to form rows; side portal feed connects rows, provides greater flexibility and hydraulic design
Easy maintenance - saves water and money by removing sediments from SedimenTrap™ devices using an air vacuum truck rather than jet cleaning with water
Long life expectancy - designed by engineers, ecologists, and biologists to ensure maximum efficiency and effectiveness

Applications

Detains, infiltrates, and conveys stormwater runoff; modular system maximizes storage volume with a smaller footprint than traditional concrete and stone systems; easy to maintain
Works in commercial, industrial, municipal, and residential settings to manage stormwater runoff; ideal for installing underneath parking lots, playing fields, and landscapes
As part of a complete stormwater management system, the StormChamber® system works with a capture device or drainage inlet to detain, infiltrate, and convey collected stormwater

Installation

Excavate trench
Line walls with non-woven filter fabric
Add SedimenTrap™ devices
Add hard stone & woven stabilization fabric
Place overlapping chambers into trench & screw together
Cut portal holes for pipe (read installation manual for details)

Maintenance Tips

Use riser pipe connected to SedimenTrap™ device as an observation well and inspect with flashlight and stick

Air vacuum when deposits approach within 6 in. of the invert height of connecting pipes between StormChamber® rows
Determine maintenance schedule with quarterly inspections and logbook
Maintenance without SedimenTrap device is done with water jet method

Materials & Sustainability

StormChamber® unit is made of thermoformed high-density weight polyethylene (HMWPE)
StormChamber® systems are made in the USA
