NCPI Toolbox
NCPI's Toolbox Program Supports Informed Engineering Design
NCPI’s Toolbox is a group of three programs that calculate Trech Load, Hydraulic Flow and Leastcost for your projects. The programs contained in Toolbox are designed to solve many of the challenges associated with sanitary sewer lines. For additional information or clarification, please contact your NCPI field representative or a member company.
Trench Load
Trench Load is a design program incorporating Marston’s equation for soil loads on rigid conduits and the latest ASTM requirements.
- See the Safety Factor associated with each bedding class for your project.
- Include Live Load calculations and specify the impact factor using AASHTO standards.
- Specify which standard should be applied (ASTM C700, Greenbook Extra Strength, or Greenbook High Strength)
- And much more...

Hyflow
Hyflow utilizes Manning’s Open Channel Flow equations to determine hydraulic solutions.
By entering the desired flow rate and slope, the recommended pipe diameter with depth of flow is instantly displayed.

Leastcost
Leastcost uses historic inflation and interest rates together with life cycle analysis to provide an equitable cost comparison between material options over the service life of an installation.
