The main reason behind stormwater management is reducing runoff and storing as much water as possible. This increases water availability for various purposes. Furthermore, it helps reduce the pollutants that flow into the rivers and lakes due to runoff.
This article will discuss the importance of the management of stormwater in detail.
Importance of Stormwater Management
Effective management of stormwater can benefit in many ways. Some of them are as follows:
- Maintaining the Natural Hydrologic Cycle: It helps in the effective maintenance of streams, aquatic life, lakes, and the natural hydrologic cycle. It also helps in replenishing groundwater and ensuring sufficient availability of water.
- Preventing Undesirable Stream Erosion: This management technique reduces the speed of the water running to streams and rivers. As a result, it helps in minimising soil erosion.
- Reducing Risks of Flooding: Areas with effective stormwater management have a low risk of flooding. Thus, they are less likely to witness the negative impact of floods after a heavy downpour.
- Protecting Quality of Water: Stormwater management prevents contaminants like grease and oil from entering the river. So the quality of water in streams, lakes, oceans, and groundwater does not degrade much.
- Avoid Soil Erosion to a Certain Extent: Stormwater runoffs can erode the rich soil cover, degrading the productivity of the land. Hence, it becomes mandatory to manage stormwater effectively, especially in sloppy regions.
- Preventing Sanitary Sewer System Overflow: Proper management of stormwater avoids water overflow.
Stormwater Management Solutions
Some of the solutions that have proven to be effective in managing stormwater are as follows:
- Green Roofs: This refers to the cultivation of crops on the rooftop of houses. Green roofs help in managing stormwater, reducing pollution and saving energy costs.
- Swales: These are used to transport water in small drainage areas with low run-off. They filter pollutants and slow down their run-off.
- Rain Barrels and Cisterns: This is a cost-effective way to harvest rainwater from rooftops. You can then use this water for domestic purposes.
- Vegetated Filter Strips: These are dense vegetation bands that direct the water run-off. They can also be used to manage run-off on roads, highways and parking lots.
- Sand and Organic Filters: These help in removing particulate metals, pollutants, and floatables from run-offs.
To design an effective stormwater management plan in Adelaide, the local catchment council and Brown Hill Keswick Creek Stormwater Board started the Brown Hill Keswick Creek Stormwater Project. The project involves many stormwater management solutions and can help you understand how the large-scale stormwater management plan works and how it can benefit people.
Stormwater management plays a crucial role in safeguarding our communities and the environment. We can mitigate the adverse impacts of stormwater runoff through effective stormwater management practices and ensure a sustainable future.
