Groundwork
Stormwater drainage is a system that channels rainwater as it comes off the roofs of buildings and off paved or unpaved areas to an appropriate and legal point of discharge. The role of the licensed plumber is to design a stormwater drainage system that prevents flooding or contaminants from entering the stormwater water catchment area. Even if you decide not to design the system yourself, as the licensed plumber on site, you will be responsible for ensuring the compliance of the system.
You need to be familiar with the basic principles that guide good stormwater design.
Groundwork provides this.
As you work through the Toolbox you may find that you want to return to Groundwork to help you complete the activities.
