A rainwater pit, also known as a stormwater pit, serves as a collection and drainage point for stormwater runoff from surfaces like roofs and driveways. It channels this water away from properties and streets.
Understanding Stormwater Pits
Here's a breakdown of the key aspects of a rainwater/stormwater pit:
- Purpose: To collect and manage stormwater, preventing flooding and water damage.
- Function: They act as temporary storage for stormwater. The water then drains into drainage pipes and is carried away.
- Location: Strategically placed to capture runoff from roofs, driveways, and other large surfaces.
- System Integration: Stormwater pits are part of a larger stormwater drain system.
How it Works
- Collection: Stormwater flows into the pit from surrounding surfaces.
- Storage: The pit temporarily holds the water.
- Drainage: The water gradually drains out of the pit through connected drainage pipes.
- Dispersal: The drainage pipes carry the water to a designated discharge point, such as a waterway or treatment facility.
Example
Imagine heavy rain falling on your roof. Without a stormwater pit, the water would accumulate around your house, potentially causing flooding. Instead, the water flows into the pit, which then directs it away through underground pipes.
