Amidst the present water disaster, a circle of relatives in Bengaluru is making waves by means of successfully addressing their water wishes with out depending on a borewell or water from the Cauvery river. By way of the use of rainwater accrued and saved from the former yr’s monsoon, Rohit Malekar and Suma Raj aren’t best beating the sizzling summer season temperatures but in addition nurturing a flourishing lawn boasting over 350 vegetation.
In an generation the place citizens are coping with acute water shortage and blistering warmth, their family serves as a beacon of inspiration, providing precious insights for different households dealing with identical demanding situations.
Whilst insufficient rainfall in 2023 is blamed for exacerbating the existing water disaster in Bengaluru, professionals consider rainwater gained within the town (an annual moderate of 800 mm) must suffice to serve its water wishes if correctly conserved via rainwater harvesting and recharging.
However regardless of rainwater harvesting being necessary for enormous homes within the town, Bengaluru drains away 90 % of its rainwater squandering a possible resolution for the water disaster that has been impacting the day by day lives of its citizens.
The vast majority of Bengaluru’s water necessities are recently met throughout the Cauvery river (60 %) and groundwater assets (40 %).
Let’s be informed extra about their water conservation efforts from Rohit and Suma.
Making each and every drop rely
Suma grew up in South Bengaluru, Karnataka, the place conservation and sustainable dwelling have been very a lot a part of her day by day existence. Round two decades again when groundwater recharging and sun panels weren’t necessary, her father had a self-designed rainwater harvesting (RWH) setup put in of their house.
So, when Suma and Rohit determined to construct their dream house, they aspired to create an environmentally pleasant house too.
The couple was once impressed by means of their son’s faculty, designed by means of Chitra Viswanath. They have been additionally impressed by means of The Higher India article that highlighted Chitra and her husband S Vishwanath’s paintings for sustainable properties. So Suma and Rohit determined to prioritise water conservation projects once they constructed their very own house in Royal Placid Format, Haralur.
Whilst their neighbours depend on drying borewells, Suma and Rohit opted for roof-based rainwater harvesting throughout the development in their 2,000 sq toes house in 2020.
“We learnt that even borewells as deep as 1,000 ft in our locality went dry through the years. This was once the rationale we selected to not drill a borewell. But even so, we nonetheless rely on water tankers because the Cauvery water provide is inadequate. This dependency will increase throughout summer season with the Cauvery water provide lowering to one-fourth of its same old amount,” Rohit tells The Higher India.
So, the couple determined to reap rainwater for non-potable functions like cleansing, bathing, and gardening wishes, excluding for consuming and cooking. This guarantees they’re unaffected by means of the depleting groundwater ranges.
Rainwater meets part of the circle of relatives’s annual water wishes. “Each and every monsoon, we save as much as 35,000 litres of rainwater. We use the harvested rainwater for cleansing and gardening functions. While, we use the Cauvery water as soon as per week and tanker provide 3 times a month for kitchen, bathing, dishes, and laundry functions, and water cans for consuming wishes. We’re a circle of relatives of 4 and rainwater looks after part of our annual water wishes,” he stocks.
Keeping up lawn with 350 vegetation amid water disaster
Nearer to their rainwater harvesting tank, the couple has maintained a lush inexperienced lawn of 350 vegetation comprising decorative, flowering, succulents, handfuls of vegetables, herbs, and ayurvedic vegetation.
But even so cleansing and different home functions, RWH tank water could also be used to fulfill their gardening wishes. The lawn calls for about 150 to 175 litres of water day by day.
“More often than not we draw water from the RWH tank to water those vegetation. Moreover, we manually re-purpose about 25 litres of water from the kitchen — leftovers from cooking and washing — for gardening,” he provides.
Without reference to the finances constraints, Suma and Rohit invested Rs 4.2 lakh in putting in the RWH setup, which required digging, masonry, waterproofing of the tank, and plumbing.
“There was once by no means a time once I doubted making an investment Rs 4.5 lakh in RWH. We attempted our absolute best to construct a sustainable space with none particular expectation of go back on funding to the level lets have enough money it,” Suma tells The Higher India.
“Along this, we additionally invested in sun panels and compressed dust blocks for all the space that supply the pleasure of adopting rather sustainable possible choices. We additionally favor the use of buckets over showers for bathing. We even have aerators for many of the taps,” she provides.
Regardless of making efforts against water conservation on the family degree, Rohit and Suma really feel they aren’t doing sufficient. “On the other hand, there’s a sense of aid that we took steps in the best course however a lot more will also be completed. I consider we want a plurality in answers to handle water shortage and RWH is a low-hanging fruit. I adore it as a result of it’s decentralised, doesn’t have a unmarried level of failure, and a few variations like groundwater recharging aren’t extraordinarily dear,” says Rohit.
Consistent with him, not up to 20 % of the homes with water connections have carried out rainwater harvesting; and fixing the water disaster in Bengaluru would require a couple of answers.
“Water conservation comes to dedication and funding relating to cash, time, and actual property. Additionally, within the present fast moving town existence, the place we rely so much on home lend a hand to run day by day chores, it’s onerous to seek out improve team of workers who’re obliged to undertake identical practices to lend a hand preserve. Therefore, it’s more straightforward stated than completed,” he says.
“However what is wanted is to concentrate on the choices to be had for decreasing environmental have an effect on after which make an informed selection in response to private context, assets, and desires,” suggests Rohit.
