Stormwater drains are designed to divert rain and melting snow from your property and into larger storm sewers. However, if the drainage system fails, water can quickly accumulate on your property, leading to flooding. Here are some things you should know about stormwater drains:
1. Blocked stormwater drains are typically divided into two types: detention and infiltration. Detention drains collect rain and snowfall directly on the ground below, while infiltration drains allow water to slowly permeate the soil and eventually reach a larger drainage system.

2. A blockage in a stormwater drain can cause flooding on your property. Water accumulates in the drain until it reaches a point where it cannot flow freely anymore. This can cause roofs to leak, foundations to sink, and waterways on your property to overflow.
3. If you notice any signs of flooding on your property, don’t wait – call an expert! A blocked stormwater drain is usually easy to fix but can quickly become a costly problem if left untreated.
There are a number of factors that can contribute to stormwater drain blockages, including:
- Construction debris: Debris such as bricks, lumber, rocks, and concrete block drains and can cause flooding.
- Tree roots: Roots from trees growing near a stormwater drain can grow into the pipe and obstruct it.
- Overflow from individual sinks or showerheads: If one sink or showerhead overflows frequently, excess water will flow toward the nearest stormwater drainage system.
Stormwater drainage systems are designed to carry only a certain amount of water at a time, so when too much water comes in contact with an overflow area orifice, it can create a blockage.
