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.
