Size

Once you have designed the layout for your stormwater drainage system you must size the pipework for the system. There are two sizing methods that you can use depending on the project type.

When sizing your stormwater drainage system you will need to comply with the requirements of AS/NZS 3500.3. You will need access to this standard to complete the activities in this topic.
