How Poor Drainage System Causes Water Logging During Monsoon?

A poor drainage system causes waterlogging during the monsoon season due to its inability to effectively deal with excess rainfall and runoff.  Water logging during monsoon season is a big problem and it disrupts the life of the people completely.  In such circumstances, roads and streets get blocked causing traffic jams and pedestrians have to face the problem. It affects the masses mentally and physically as people and especially, children and elderly people have to face problems on such waterlogged roads. Sometimes it paved the way for various kinds of diseases. A poor drainage system can lead to waterlogging during monsoon seasons due to its inability to effectively manage the excess rainfall and runoff.  We are discussing in this article how a poor drainage system contributes to waterlogging. The following are the factors to contribute causing a poor drainage system leading to waterlogging:

LIMITED OR INSUFFICIENT  CAPACITY

When the capacity of the sewage system is insufficient to handle the amount of rainwater produced during heavy monsoon rains, the excess water pools on streets and low-lying areas. It creates a number of problems for the people living in the area.  

BLOCKED DRAINS

In case the drains and channels within the system are clogged with debris, sediment, or other unwanted objects, it can create obstruction. It reduces the drainage system's efficiency and can lead to water accumulation. Various kinds of debris, dirt and other materials may add to drains and cause water to back up and flood areas.

EFFECTIVELY DESIGNED DRAINAGE SYSTEM

A drainage system should be properly designed to accommodate the local area and rainfall patterns.   If the drainage system is not designed effectively and properly,  it can cause water to build up and block the draining from populated areas and towards appropriate outlets, leading to waterlogging. For it, the authorities responsible for managing water draining systems should always use plumbing items and pipes of well-reputed companies.  

LACK OF MAINTENANCE

To prevent clogging we need to have a vigil by ensuring the regular maintenance of the drainage system. If proper maintenance is not carried out, the drainage channel may become overgrown with vegetation, sediment  etc. and structures can deteriorate making proper drainage difficult.

ENCROACHMENTS

Unauthorized construction on natural drainage paths may dislocate the flow of water. Blocking these paths leads to water accumulation in unforeseen areas. As a matter of fact, encroachments and unauthorized construction on such paths can have significant negative impacts on the flow of water and can lead to various problems:

INADEQUATE INFRASTRUCTURE

Areas with inadequate infrastructure may lack proper drainage and stormwater pipes or other components needed to deal with excess stormwater. Without these, water cannot be diverted or safely stored.

RAPID URBANIZATION

We have seen that rapid urbanization often leads to an increase in paved or impervious surfaces such as streets, buildings, and parking lots etc. These surfaces prevent rainwater from being absorbed into the ground and instead, drain it away.  In fact, poorly planned urban areas located in low-lying areas are particularly vulnerable to waterlogging.  Defective drainage in these areas can cause prolonged water accumulation, affecting both infrastructure and residents

TOPOGRAPHICAL STRUCTURE

In terrain with steep slopes or uneven topography, a poorly designed drainage system lacks the appropriate slope to facilitate the smooth flow of water. It may lead to water stagnating in certain areas.

OTHER FACTORS

Sometimes due to a lack of proper coordination among different authorities responsible for various parts of the drainage system may not coordinate their efforts effectively. It may also cause gaps in coverage and reduced overall system efficiency.

To control and prevent waterlogging during monsoons, it is important to invest in well-designed, maintained, and properly functioning drainage systems like APL Apollo drainage system. It includes routine maintenance, regular cleaning of drains, proper urban planning to account for drainage needs, and implementing sustainable water management practices.
