This explains how to use a simple online calculator, that will design, and size, all the stormwater or rainwater pipes for a building site.
The program will calculate the pipe sizes, grades, invert levels, pit and grate sizes, and the length of funnel sections to reduce the downpipe size.
It also produces a CSV file for download, and a template to past it into.
The spreadsheet also produces a graph of the pipeline elevation.
