Stormwater Attenuation Guide

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...

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 col...

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 storm...

While rain brings cheers to the face of most people in the world, heavy rainfall brings gloom to urban dwellers. As cities face a scarcity of pervious surfaces, the rainwater does not get managed naturally. While most cities comprise a stormwater drainage system to carry away the rainwater falling on the impervious surfaces to the nearby drainage system, it often fails to work in case of heavy rainfall. As a result of this, there is a flood and non-point source solution. No doubt, the government takes many measures to prevent these adverse situations. But as a citizen, we should all take some measures to deal with flood and stormwater pollution. In this write-up, we have shared some simple tips to reduce stormwater pollution. 1. Install a stormwater attenuation plant A stormwater attenuation system comprises a tank and a flow control device that together help in managing the volume and flow of stormwater from a residential or commercial property to the main drainage system. ...

Over the last few years, we have witnessed how repeated rainstorms cause floods. Heavy rainfall can have many adverse impacts, such as non-point source solution, damage to infrastructure, and power outages. All these issues happen due to scarcity of pervious surfaces and trees, both of which help in maintaining the natural hydrological balance. In cities, the cemented and concrete surfaces contribute towards waterlogging. While stormwater drainage networks help in preventing flood by channeling the stormwater from its source destination to the nearby water bodies, it fails in case of heavy rainfall. To reduce the burden on stormwater drainage networks, every residential and commercial property must maintain hydraulic balance. In this write-up, we have enlisted a few easy-to-implement techniques for stormwater management. 1)  Install a stormwater attenuation plant - Making use of a  rainwater attenuation tank  can help in preventing waterlogging by detaining mo...

To address the issue of flood in urban areas, many local governments have enforced the principle of hydraulic neutrality on every residential property. This means every homeowner needs to ensure that most of the rainwater falling on a house needs to be retained on that site. The aim is to reduce the pressure on stormwater drainage networks so that the risk of stormwater flooding in heavy rain events is reduced. Another benefit of achieving stormwater neutrality is that it helps in restoring the natural hydrological balance. But achieving hydraulic neutrality can be difficult these days because the natural, pervious surfaces have been replaced by concrete surfaces. Moreover, due to the scarcity of green plants, the natural stormwater attenuation system has been disturbed. In this write-up, we have shared a few simple tips for achieving stormwater neutrality at your home. 1. Install a stormwater attenuation plant A  stormwater attenuation tank  can effectively detain the e...
