Tables 4, 5, 6 and 7
provide cumulative storage volumes for the SC-160LP, SC-310, SC-740 and DC-780 chamber systems.
This information may be used to calculate a detention/retention system’s stage storage volume. A spreadsheet is available
at
www.stormtech.com
in which the number of chambers can be input for quick cumulative storage calculations.
Product Specifications: 1.1, 2.2, 2.3, 2.4, and 2.6
