Stormwater Design Calculator

This calculator is designed to calculate how much on-site drainage storage is needed to meet the Town’s requirements for managing drainage in storm events. It takes into account 20 and 100-year Average Recurrence Interval (ARI) rainfall events.

Note: The calculations provided within the spreadsheet are recommended based on normal rainfall conditions. Excessive stormwater conditions can cause overflow depending on the soil type, e.g. rock, clay, limestone etc.
