4 Methods To Prevent Urban Flooding
Four Methods Being Used In Urban Areas To Stop Flooding
Business owners in Lafayette, LA, know that high water entering a property from flooding is an eventual possibility. While the cleanup by a water damage and restoration company can make it “Like it never even happened,” preventing it from happening is more ideal. Keeping sandbags or having a barrier system may reduce the impact, but a largescale system is a key to reducing the high cost of a citywide event.
1. Rainwater Harvesting
Once heavy rains come, they create dirty and polluted stormwater. Instead of letting the water flow down buildings and into streets, many cities have installed systems to collect and store it. Massive tanks can hold thousands of gallons, which can then be used for flushing toilets, irrigating gardens and fighting fires.
2. Permeable Surfaces
A trending more modern flood prevention method is the use of permeable, or porous, pavement. During a storm, the rainwater runs over streets and sidewalks and heads straight for the sewer drains. Porous pavement works to absorb some of the rain, which then gets filtered through the layer of dirt and rock below it. An additional benefit is that this kind of pavement is easier to maintain.
3. Upgraded Sewer Systems
A common cause of high water is a sewer system pushed beyond its capacity. In many cities, the systems are old and have traditional piping that is prone to rust and corrosion. To deter flooding, systems are being upgraded with modern materials and methods to better separate rainwater from the sewer water.
4. Green Roofs
Water brings life, so many cities are encouraging building owners to turn dark, heat-absorbing, rain-collecting roofs into lively green spaces. Covering the roof with vegetation can decrease the overall heat of a city and foliage thrives on rainstorms. Plants are natural water absorbers, so a green roof reduces runoff.
Although high water from flooding is a common issue, new methods and materials are being used to reduce the problem and minimize the damage it can cause.
