How does the stormwater drainage system work?
The stormwater drainage system receives rainwater when runoff flows into drainage structures. Gravity moves the water through the pipes until it reaches a waterway. Stormwater systems can be very short, with only one drain and one pipe, or they can be a complex series of drains and pipes that lead to a waterway.
