CST - Model CrystalClean -Dual Chamber Stormwater Separator

In twin vault systems, the trash screening basket and two of the three baffles are in the front vault. A third baffle, the spill protection reservoir, and the coconut fiber filter are in the second vault. Flows enter the device from the endwall, top, or either side wall of the front vault, pass through the treatment elements in that vault, and then cross over to the second vault via a connector pipe. The flows then pass through the remaining elements in the second vault, and exit out the back of that vault through the endwall, or either side wall. The two vaults can be parallel, as shown in the sketch above, or in line. They also can be set up in other arrangements to accommodate your storm drain design. You may want to look at the sketches in the “Array” section of products to see other possible arrangements. The sizes of our twin vault devices are shown in the Technical Details tab. In some areas, other sizes may be available.
