Rain Water Harvesting is not new..Smarter concept seems to have saved not only water but also reduced huge costs.
Bangalorean solving dried borewell issue utilizing pre-monsoon showers
Here introducing an example of overcoming adversity of Bengalureans who are utilizing monsoon rainwater this year as bore wells are running dry and the groundwater level is quickly exhausting. At the point when the city got hefty monsoon showers this year in2019, the residents of Metropolis Gurukrupa apartment (88th-floor high rise) in Singasandra had spent ten days depending solely on the rainwater. However, they had both the Cauvery water supply and multiple bore wells in their building. Ganesh Shanbhag, a local of Hubli and lives in Metropolis Gurukrupa, an employee of a Bangalore-based startup and thinks profoundly about nature. To provide a reliable flow of water to the occupants in his complex, he chose to take advantage of readily available rainwater as a source. He mentioned, "An early warning bang us all when all of our five borewells dried up as a result of the restoration of the lake undertaken by the Begur Lake regime, which was about five kilometres far from our housing complex."
At that point, the occupants chose to make the best of pre-rainstorm showers before they started and began introducing a Rainwater Harvesting System (RWH) in March 2019. In contrast to other people, they didn't include a seller yet sourced all the RWH framework pieces on the web and their own built one for their apartment. It likewise ends up being financially savvy as the whole RWH framework has introduced under just Rs. 20,000/-.
Tackling the issues ……..
Previously, as a prompt solution to the issue, the apartment resorted to buying water private large haulers and went through around Rs.50,000 that month to use 88 flats. It appeared to be costly, yet Ganesh eventually found a sustainable solution to it.
Utilizing rainwater measuring instruments, Ganesh realized the city got 1300mm of precipitation that year, which is adequate for 80 percent of the city's needs. However, with huge zones progressively being concreted, rainwater drains into the sewage system rather than the ground. RWH is not a Nobel idea. Private buildings with more than 40 houses have ordered to have an RWH and sewage treatment framework even though Ganesh's apartment has the arrangement for it, with no RWH framework.
With the assistance of the homeowners' Welfare Association, Ganesh found several individual homeowners eager to spend their free time designing the whole framework.
Material science behind the framework…….
It started by understanding the material science behind the framework. To do this, Ganesh surveyed a few other flats with RWH frameworks previously introduced and understood the physics behind its performance. He saw that many were utilizing pop-up channels, which acquired a high working expense. Until he was confident that the machine could be useful, Ganesh put some money for the raw materials required, like piping and tubes, filters, channels, etc.
Ganesh explained, "The occupants consented to contribute cash, and we invested just Rs.20,000/- to gather the crude material. I likewise bought disc-shaped channels over pop- up filters to make it inexpensive. The main distinction between the two is that pop-up channels require broad support, while circle channels require manual cleaning. This implies there is zero working expense whenever done by residents."
Mind-blowing Strategy behind success…….
Ganesh plotted out paths to direct the water supply from the roof deck to four subterranean reservoirs built to store rainwater. "Afterwards these roof deck water were channeled across multiple outlets then sheathed into two tubes with a mesh filter of five layers. These filters have been designed to keep back hazardous sludge and several other contaminants. "The siphon outlet fitted with the plate channels that guarantee fine cleaning of the water, making it consumable," says Ganesh.
There are several sheets of the net to maintain water flow such that on the off chance that one blocked up, the other would keep down the residue. The treated water flows down towards the storage tanks for use, while the wastewater is moved towards dried out bore wells through channel pipes. When all four water tanks were up to their maximum, the surplus water would be able to leak into a refill chamber, which would filter the water that further which channels the water into the ground, accordingly expanding the groundwater levels. Four pipes were attached to the Twelve refill pits in the complex to drain the rainwater to the revive pits.
Their RWH framework comprises eight channels. So far, the occupants have gathered around two lakh liters of water supply.
Implementing Togetherness ……
Incorporating concept and prototype was Ganesh's innovation, and it had successfully executed with the aid of several other occupants, some of whom were engineers and plumber working in the apartment building. At last, they figured out how to purchase water for February, yet in March and April that year, they didn't and thus figured out a low investment. The project was completed by the end of that crisis month, and at last, in March 2019, when the city hit monsoon, the framework ended up being fruitful.
An Unpaid hobby for him…...
Ganesh mentioned that, “There is no fixed cost to introduce the framework and that it would rely upon the size and number of occupants in the complex.” He does, nonetheless, quote the furthest constraint of Rs 3,00,000 as a rough approximation.
He never expects a penny for his hard work and innovation; instead, he contributed Rs. 3,00,000 to buy essential crude material. He valued his responsibility and took this as an interest, and might want to work with different complexes who have confronted water issues and need to execute this."
Progress mimicked further…..
Srivibha Jeevarathinam, a member of the Resident Welfare Association of GR Srinivas Apartment complex in Bangalore, in the wake of perusing a news story about Ganesh, he got roused and mirrored Ganesh's innovation inside his complex. Seeking tips from Ganesh, together with the cooperation of his property's plumbers and electricians, they planned and introduced the framework within a month.
Srivibha Jeevarathinam expressed," Though we keep on relying upon big water tankers, the months when there is adequate training, we don't, and this has diminished our costs significantly." Impressed at their efforts, several residential members in their region began to approach them to introduce the RWH frameworks. It was a groundbreaking development."
Anticipating intense precipitation in July, August, and September, several other residents plan to capture 12-13 liters of rainwater via their RWH system. Until now, over 30 high rises in Bengaluru have received Ganesh's RWH framework and proceed to realize the benefits.
