2.0 STORMCEPTOR® CD SIZING PROGRAM
This section provides a general description about the Stormceptor® CD Sizing Program,
limitations and minimum specifications for installation of the Sizing Program.
2.1
General Description
The Stormceptor® CD Sizing Program version 4.0.0 is proprietary sizing software which
applies a mathematical model to estimate sediment accumulation, hydrology and long
term pollutant removal. The Sizing Program has been calibrated to field monitoring
results from actual Stormceptor® units that have been monitored in North America with a
resulting correlation coefficient (R2) of 0.94 as presented in Figure 2.1.

Figure 2.1 - Calibration Between Simulated and Field Monitoring Results
The Sizing Program is based on continuous hydrological simulation of hydrology, mixing
models and total suspended solids (TSS) settling. The sizing methodology can be
described in three processes:
•
•
•
Determination of flows from geographic historical continuous rainfall data;
Build-up and Wash-off of TSS from impervious land areas; and
TSS transport through the Stormceptor® (settling, mixing, by-pass).
The use of a calibrated model is the preferred method for sizing stormwater quality
structures for the following reasons:
