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.
