Why Stormwater Mismanagement is a Big Problem? How to Prevent It?


While rain brings happiness and cheers to everyone’s face, excessive rainfall is a cause of concern for urban dwellers. When rainwater falls on the impervious city surfaces, it does not get absorbed; rather it starts accumulating and causes waterlogging. The stagnant water often becomes the breeding ground for mosquitoes which is a vector of many life-threatening diseases. Plus, as water is an excellent solvent, it can carry away dirt and pollutants lying on the concrete surfaces. When this dirty water is drained to the nearby water bodies via stormwater drainage networks, it disturbs the aquatic ecosystem. Plus, when consumed by human beings, it causes several water-borne diseases, such as diarrhoea, hepatitis A, cholera, typhoid, amoebiasis.

To prevent all these issues, it is important to manage the stormwater properly. In this write-up, we have shared a few tips in this regard.

1)  Install a stormwater attenuation plant- A stormwater attenuation tank can collect the entire rainwater falling on a residential or commercial campus. The water captured by this tank can be later released to the Greenfield areas or stormwater drainage network by using a flow control device. In this way, it helps in preventing floods. Moreover, it allows us to control the quality of water before releasing it to the nearby stormwater drainage network. Therefore, it helps in preventing non-point source water pollution.

2)  Introduce more pervious surfaces- In a natural setting, soil can absorb more than 50% of the rainwater. By replacing the concrete pavements, we can ensure that more water is absorbed by the ground. As soil is an excellent water filter and a natural absorber of water, introducing it to your garden and streets can help in preventing water pollution and floods.

3) Implement green infrastructure practices- Green infrastructure practices, such as bioswales, vegetated rooftops, and absorbent gardens make the combined use of soil and green plants. By controlling the flow, volume, and quantity of water, they help in preventing floods and water pollution.


Apart from following all the above-mentioned tips, you should maintain good hygiene in your residential campus as stormwater runoff can carry dirt, chemical, and debris to the nearest stream, or lake. Animal litter, plastic bags, and hazardous household products should not be disposed of in open as they can poison aquatic life and affect drinking water sources.

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
