Single Vault Systems

Please refer to the product overview for details of operation. The maximum flows shown are usually the 10-year or 25-year flows taken from the pipe system design chart. Water Quality flows are typically 20 to 30% of this flow. Our designs analyze and can accept the largest expected storm flows, but center their efficiency around the water quality storms. Your local regulations may allow slightly higher than maximum flows, or may require slightly lower flow limits. The chart below is to get you started. Please visit our Links & Downloads section to get a CrystalStream Design Sheet or complete our Online Design Form to get a design specific to your area.

In single vault systems, all elements are in one vault. Flows enter the device from the endwall, top, or either side wall at the front, pass through the treatment elements, and then exit out the back of the device through the endwall, or either side wall. The sizes of our single vault devices are shown below. In some areas, other sizes may be available.
