Prinsco Stormwater Storage Solutions
HydroCAD provides full support for the stormwater storage products offered
by Prinsco, Inc.
including HydroStor® stormwater chambers and all dual-wall
pipe products including GoldFlo®, GoldFlo WT®, EcoFlo
100® and GoldPro Storm.
partnership allows Prinsco products to be easily used within any HydroCAD model
for stormwater storage, detention, or infiltration. HydroCAD includes
complete Prinsco storage definitions, plus an interactive chamber
wizard for easy layout, pricing, and modeling of
underground storage systems.
Prinsco pipe products are supported in
HydroCAD-10 "build 4" or later.
HydroStor HS75 and HS180 are supported in HydroCAD-10 "build 14"
or later. The latest HydroStor HS31 will be supported in HydroCAD 10.1-5a,
which also provides updated end-cap storage.
How storage is modeled
storage typically appears in a HydroCAD model as part of the
storage definition for a "pond". In the simplest case, HydroCAD
calculates the total available storage, including the interior of the chambers
plus the void space in any surrounding stone.
For a more complete analysis, a full stage-storage curve is calculated so that
an inflow or runoff hydrograph can be routed through the pond. The resulting analysis indicates the water
levels attained throughout the rainfall event, as well as any discharge
that may occur through outlet devices or infiltration into the surrounding
Flexible storage options
Each HydroCAD pond may include an unlimited number of storage definitions as required
to describe its overall storage characteristics. This makes it
easy to model complex storage arrangements, such as a combination of multiple
chambers, catch basins, or other contributing volumes.
But the most significant feature is the ability to embed (bury) chambers in a
bed of stone, and have HydroCAD automatically calculate the combined
storage at any water surface elevation. This makes it easy to determine
the storage for virtually any configuration of storage chambers, without
resorting to any manual calculations.
HydroCAD can also model almost any imaginable storage arrangement, including
layered chambers of different sizes combined with auxiliary storage from
adjacent pipes and catch basins, and even the above-ground areas (parking lot)
that may provide overflow storage for certain events.
Prinsco stormwater products
Setting up a pond to use Prinsco chambers or pipe storage is a simple process:
Just pick the desired product and size from the drop-down lists, and specify the number
of chambers (pipe lengths) plus their elevation. The HydroCAD chamber wizard
automatically calculates the overall size of the system based on the
manufacturer's recommendations, or you can customize the layout to suit your
definitions for Prinsco dual-wall pipe are based on the actual inside diameter and
displacement as listed here.
