Bengaluru Water Crisis and the Heat Alert: What Measures Can Be Taken?

Bengaluru has fined 22 households for allegedly 'misusing' drinking water for non-essential activities, as the city deals with its worst water crisis in decades.

The Bangalore Water Supply and Sewerage Board (BWSSB) has collected a fine of Rs 1.10 lakh in just three days. Authorities have urged Bengaluru residents to use water sparingly, as temperatures rise and groundwater levels fall due to a lack of rainfall. In mid-March, Karnataka Chief Minister Siddaramaiah announced that Bengaluru was short 500 million liters of water per day (MLD) compared to the real requirement of 2,600 MLDs.

Amid the water crisis, temperatures in Karnataka rose above 40 degrees Celsius in several districts. The Indian Meteorological Department (IMD) has issued a heatwave advisory for six districts in Kalyana Karnataka during the next three days, with daytime temperatures in Bengaluru anticipated to soar by up to 2°C. The IMD has cautioned that North Karnataka districts such as Kalaburagi, Yadgir, and Ballari would face a heatwave with warmer nights during the next three days.

According to Climate Central's Climate Shift Index map, Bengaluru and other regions of Karnataka are expected to see extreme heat in the coming days. As temperatures climb, homeowners should take care to limit the consequences of the heatwave.

To combat disaster, the people of Bengaluru can look up to several measures.

Rainwater harvesting and water conservation in home construction can be a good option. We can recharge wells placed at key locations to control the flow of surface water. For the purpose of facilitating water passage through layers, each well is equipped with a filter system and a silt trap that utilizes various aggregates. 

In order to access deeper aquifers, a recharge well can store more water and restrict its flow via porous strata. To restore and sustain his farmhouse's ecosystem, we can use applied permaculture concepts. Renewing and reusing existing materials is central to permaculture, which aims to create an ecosystem that can sustain itself. By utilizing an appropriate ground cover and mulching with dead leaves and wood chips, one of the main results of permaculture is a decrease in water consumption.


By following these efforts, the city may try to alleviate the water issue and ensure a more sustainable water future for Bengaluru.
