Municipal Flood Prevention

4/21/2021 (Permalink)

It is nearly impossible to control natural factors that lead to high water conditions, but many communities try to take steps to reduce the risk of flooding. Various methods of flood control are regularly practiced, such as

  • Reforestation
  • Levee, dam, and reservoir construction 
  • Floodwater diversion, including the use of floodways

Many of the modern methods used in urban and rural areas today have their roots in ancient flood prevention practices. 

Sponge Cities 

This method is commonly used in China and involves creating an urban environment where water can hold, clean, and then drain water naturally. This ecological approach involves using rainwater for daily living, such as irrigation gardens, flushing toilets, and recharging aquifers. 

Flood Plains and Overflow Areas

Vast areas of open land around rivers play vital roles in water management and natural flood protection. Additionally, many city planners include "parks" at lower levels than the surrounding neighborhood. These overflow areas become ponds during storms or heavy rainfall and may save surrounding homes from water-filled basements. 

Separate Systems for Storm and Wastewater

Many cities have taken an important step by running separate underground pipe systems for draining rainwater out of the sewer systems. This reduces the burden on wastewater treatment plans and improves the efficiency of functionality. Additionally, city workers take steps to keep sediment, debris, and other items out of the sewer system.

Sustainable Drainage

This refers to replacing non-permeable materials with permeable solutions. For example, a concrete walkway up to the front door won't absorb any water, concrete is non-permeable. However, a decorative stone walkway or a gravel path can absorb water. The more water is absorbed by the ground, the less risk of high water and can help stop flooding. 

Flood prevention is a continued study that involves improved efforts. If you want tips on how you can help in prevention efforts before high water situations, talk to a flood remediation professional in your area.
