 DASH
- Detention and Sewer Hydraulics TM
Software Program from the American Concrete
Pipe Association provides design engineers
and other users with a complete set of
design tools to prepare, calculate and
evaluate comprehensive storm water detention
systems using concrete pipe.
The
software program consists of four modules:
Storm
Water Detention Volume Calculation -
This module allows the user to select one
of four methods to calculate the volume
of detention storage for the project, including
TR-55, TR-20, HEC-1 and the Modified Rational
Method. The program database contains information
on how to obtain rainfall data for each
method. All the inputs are done in a Windows'
environment.
Storm
Water Detention System Design - This
interactive design module allows the user
to lay out pipes of any shape and size
to scale and alerts the user when the volume
required for the project has been reached.
The program will determine the required
class of concrete pipe for the given loading
condition, calculate the cost of pipe,
fittings and backfill material (if unit
costs are known) and print a cost report.
If unit costs are not known, the program
will print a quotation request form. The
final layout diagram can also be printed.
Storm
Sewer Design Calculation - This module
consists of a powerful design tool to assist
in storm sewer design. The program will
calculate flows for each pipe in the system
using the rational method and then calculate
the required pipe size and slope, and invert
elevations of the pipe at all downstream
manholes. The user may adjust the size
and slope of the pipes and provide additional
drops at manholes to modify the design
as desired. The program will then recalculate
all other design parameters. Once the design
is complete, the program will display a
checklist comparing capacity of each pipe
to the design flow; and flow velocity to
the design velocity.
Sanitary
Sewer Design Calculation - This module
provides a useful design tool to assist
in sanitary sewer design. The program will
calculate flows for each pipe in the system
using population densities, average per
capita flow rates and peaking factors.
It then calculates the required pipe size
and slope, and invert elevations of the
pipe at all downstream manholes. The user
may adjust the size and slope of the pipes
and provide additional drops at manholes
to modify the design as desired. The program
will then recalculate all other design
parameters. Once the design is complete,
the program will display a checklist comparing
capacity of each pipe to the design flow
and flow velocity to the design velocity.
