We are sensitive about sharing a river. We gregariously welcome home water-tankers. We are the lifestyle-conscious Bangaloreans, who understand the water problem of this ever-expanding city like never before. But are we being tunnel-visioned in meeting our immediate water requirements and not looking at the dire dry future?
Here’s a fact. The average water consumption of a Bangalorean per day is 140 litres. The overall supply of water from the Cauvery as well as ground water sources to the city is at 1023 million litres/day (MLD). The total demand for water in Bangalore is 1342 MLD. That means 319 MLD less than the requirement or over 22 lakh people without their average quota of water.
The sudden realization is that you are one among the two million and that’s not a small number to get out of. So, how do we tackle this?
Here’s another fact. Despite a regulation from the governing authorities to set-up rainwater harvesting systems, many Bangaloreans are still ignorant about it.
We may not have abundant ground-water, but we have good god-sent monsoons. Let’s collect the rain. It’s a simple solution to a serious problem. Just like the lesson we taught the kids to put a bucket under a leaking tap; a lesson to save water and to replenish it. The rainwater harvesting system is a one-time set-up that may cost around Rs.40K for a 60X40 site/house. On a rainy day, this would accumulate 54K litres! You can save a part of this and let the rest to percolate and replenish the ground-water. This, against the cost of water-tankers at Rs.3000 for a month, is very economical. Plus, it consumes no electricity. What’s more? A water-sustained future for you and the city.
Rain rain, come again. People here are in vain.
