How does storm drain work?
Storm Drain 101 They work by diverting rainwater and melting snow and ice into nearby bodies of water. Every time it rains, water runs off of your roof, through your gutters, and into the street. It picks up debris and pollutants along the way from your home and yard (and the street).
What is stormwater and why is it important?
Stormwater is rainwater or melted snow that runs off streets, lawns and other sites. When stormwater is absorbed into soil, it is filtered and ultimately replenishes aquifers or flows into streams and rivers.
How do you use storm water?
- Irrigation. Irrigation is the most common use of harvested water and therefore examples and case studies are more plentiful for this use.
- Water features.
- Sanitary sewer flushing.
- Street cleaning and dust control.
- Vehicle/building washing.
- Fire suppression.
Why is stormwater a problem?
Uncontrolled stormwater runoff has many cumulative impacts on humans and the environment including: Flooding – Damage to public and private property. Eroded Streambanks – Sediment clogs waterways, fills lakes, reservoirs, kills fish and aquatic animals. Widened Stream Channels – Loss of valuable property.
What is the difference between stormwater and rainwater?
However, rainwater can also be used for low-risk purposes such as washing clothes, washing cars and filling up swimming pools. Stormwater is basically the rainwater that lands on the ground such as roads, gardens, footpaths, driveways, gutters, down pipes, runoffs and lawns.
How do you get storm water?
Dig a trench. Use a shallow, gravel-filled trench to catch and slow runoff, especially at the base of a slope or alongside a driveway or patio. For slopes, consider creating a dry creek to catch, slow down and direct runoff, perhaps to a rain garden (see below).

Wastewater pipes should not be connected to the rainwater system. If the rainwater gutters and gullies are connected to the wastewater drain, rainwater could overwhelm the drain and cause flooding.
What kind of pipe is used for a storm drain?
Corrugated plastic pipe is ideal for storm sewer systems, such as underground retention/detention systems as it has the structural strength and watertight joint systems to control runoff quantity and rates of release.
How do you solve stormwater problems?

- wash your car on grass or gravel or take it to a car wash.
- reduce use of pesticides, herbicides and fertilisers.

Is storm water and surface water the same?
Stormwater that does not soak into the ground becomes surface runoff, which either flows directly into surface waterways or is channeled into storm drains, which eventually discharge to surface waters. It does not flow to a wastewater treatment plant.
How does storm water become contaminated?
