Stormwater Drainage System FAQs
How can stormwater enter our wastewater system?
Stormwater enters wastewater systems through illegal connections, cracks in sewer pipes, or when sewers overflow during heavy rains.
How does stormwater drainage work?
Stormwater drainage systems collect runoff from hard surfaces and channel it into basins or ponds that reduce flooding and filter pollutants before releasing water into natural bodies.
What can go down stormwater drains?
Only rainwater should enter stormwater drains. But oil, chemicals, litter, and waste are often carried into waterways, harming water quality and ecosystems.
What are the best practices for maintaining stormwater systems?
Some of the best practices for maintaining stormwater systems include:
- Regularly clearing debris from drains.
- Inspecting and repairing infrastructure.
- Managing surrounding vegetation to ensure clear water flow.
How can individuals contribute to effective stormwater management?
Individuals can help reduce runoff pollution by installing rain barrels, using permeable paving, maintaining natural vegetation, and avoiding harmful chemicals.
What technologies are advancing stormwater management?
New technologies include:
- Real-time monitoring systems.
- Green infrastructure like green roofs and bio-swales.
- GIS tools for optimising stormwater system design and management.
