How to prevent stormwater flooding in your area


Heavy rainfall is a major cause of concern in cities because due to lack of pervious surfaces the water does not get managed in its natural way? While storm drains are in a place to prevent waterlogging from concrete roads, paths, and buildings, they fail in case of heavy rainfall that may lead to clogging of drainage pipes. And, thus floods are commonplace in cities. Waterlogging can cause severe damage to the infrastructure and may badly impact the health of citizens. Water being an excellent solvent carries away everything falling in its path, and cause non-point source pollution. To deal with these issues, we need to recreate the urban infrastructure in such a way that the rainwater is managed in its natural way. While it is difficult to change the entire infrastructure, we can make certain additions to our residential and commercial complexes to achieve stormwater neutrality. Here we have shared a few tips in this regard.

1) Install stormwater attenuation plant

A stormwater attenuation tank helps in preventing flood by collecting the entire rainwater falling on a residential or commercial campus. Once it stops raining, the stormwater detained in this tank can be diverted into the main stormwater drainage network at a moderate rate, thereby preventing pressure on its pipes. Alternatively, this water can be reused for washing cars or gardening.

2) Implement green infrastructure practices

Green infrastructure practices, such as bioswales, permeable pavements, green roofs, and green streets make combined use of soil and green plants to restore the natural hydrological balance. Planting trees can help in preventing floods as they are excellent water absorbers and also controls the flow of rainwater. Plus, they also help in preventing soil erosion and promote surface water recharging.

Green infrastructure solutions, such as rain gardens, permeable pavements, green roofs and infiltration planters also provide recreational benefits.

With the above-mentioned techniques, you can achieve stormwater neutrality. These techniques are easy-to-implement, cost-efficient, and require lesser maintenance.

What are soakaway crates & How does soakway crates work?

Soakaway cases act as a more progressed sort of an old-fashioned jettison or pit. These were customarily packed with rock and utilized as a range for stormwater and abundance surface water to douse into. This strategy can still be utilized but it comes with a few issues. the foremost issue is that, definitely, under locale accumulates soil and flotsam and jetsam which stock up the purge space inside the discard giving the water no place to run into, rendering nonexistent put futile after time. Soakaway frameworks incorporate no such issue. The cellular cases are made to act as an underground supply to assemble the stormwater from determined rain. The cases, made up of plastic which clip together effectively to form a box structure, are commonly utilized in different distinctive ventures from commercial to the household. What is a soakaway crate? A soakaway case is routinely a plastic carton that licenses water to saturate through the soil instead of making a construct-up of surface wat

What is Stormwater attenuation &how does it work?

There’s no address around it – the climate is taking a turn for the more regrettable. In later a long time extreme storms and flooding have gotten to be commonplace, and indeed in the event that they hadn’t, winter is fair around the corner – with floodwaters undermining potential long-term harm to buildings and infrastructure. So how can you secure yourself from the harm and chaos caused by the coming storms and the rising tide of floodwater?   The reply is Stormwater Weakening. But what does that mean?    Attenuation relates to the capacity of abundance stormwater amid the top of a storm, taken after by controlled discharge of the put-away water. The rate of discharge is outlined to be lower than the rate of runoff from a location earlier to advancement, successfully mirroring the common streams from the location.   Why attenuation is necessary   The development of difficult surfaces (rooftops, patios, carports, etc) on regions of arriving that were already undeveloped, changes the w

What Are the Implications of Stormwater Mismanagement? How to Deal with Them?

Heavy rainfall is a cause of concern for urbanities because due to the scarcity of pervious surfaces, the water does not get managed in its natural way. In a rural setting, most of the water is absorbed by tree canopies and soil. However, in cities, this natural system is replaced by big buildings and concrete surfaces. As a result, flooding and waterlogging are commonplace. While cities generally comprise a well-designed stormwater drainage network, it fails to work properly during the time of increased peak discharge. When a higher volume of water does not get removed from the concrete surfaces, it keeps on gaining weight. As a result, large volumes of water cause structural damage and erosion. When runoff water does not infiltrate through the ground, it carries away all the dirt and pollutants to the storm drains. When this polluted water is drained away to the rivers, it affects the aquatic ecosystem. The excessive amount of pesticides and fertilizers in the water suppo
