10.0 System Sizing
To assist in the design of the HydroStor chamber systems, a Chamber System Design Aid (XLS)
calculator is available on Prinsco's website, www.prinsco.com. This calculator enables the user to
input the design criteria and estimates the quantities needed for the system. Contact your local
Prinsco representative for further information on use of the calculator.
10.1
Sizing a HydroStor Chamber System
The design of a detention or retention system is the responsibility of the design engineer for the site
being developed. The following steps provide guidance and information necessary for the design of
the HydroStor system. All calculations and design functions must be accomplished and approved by
the design engineer. If you need technical assistance with the layout or design of the HydroStor
system contact your local Prinsco representative.
STEP 1:
The determination for the volume of water to be stored is the sole responsibility of the design
engineer based on local codes, regulations, and design practice.
STEP 2:
To determine the number of chambers needed, divide the amount of storage required by the
volume of the chamber selected. The volume of storage available per chamber is provided in Table
9.
