4) Road Construction and cleaning
5) Gardening purposes

1 & 4, which utilize the most water among this list will never be curbed. How can BBMP stop its favorite money-making schemes?

Water scarcity in Bangalore is becoming bad to worse now.

We now know clearly what happens if this is not addressed immediately to Brand Bangalore.

We also know the root cause and how to rectify.

Now it is high time we address this on top priority from a personal level to the Government level.

A typical bucket size is 20 to 25 litres. And one bucket would be sufficient for a bath. That's what I consume, atleast.

One of the worst culprits in wasting water are the house maids who open the tap in full flow. Repeated requests to my house maid have fallen in deaf ears. So now I reduce the water flow at the source when she comes to wash the vessels.

Also wherever possible it is better to eat in plantain leaves as it serves dual purpose of saving water as well as being
healthy.

No shaving. Many of our cricketers don't anyway.

I don't think a shower takes more than a bucket of water. Try filling your bucket with shower and see how much time it takes.

I have no maid for the same reason, I clean the house myself with minimum water and also try mostly to manually clean dishes rather than using the dish washer most of the times.

I don't see any solution being planned other than short term efforts to dig more borewells which are necessary now. I was reading a article that there are 2,50,000 recharge wells around Bengaluru not including the ones in the houses.

Water management is a long term process. Any amount of recharging will not help without recycling and using it to fill up lakes when the rains are deficient. Treated water is not used and is being wasted with private users not interested in it since they can have their own borewells. Even BBMP does not mandate its use compulsorily in city infrastructure building.

I recharged my borewell directly filling it with filtered rain water without using it much for 6 years now and it has gone dry this time. We need to look at how much we are drawing.

Saw a message from BWSSB chairman. For the 1.4 crore population with 150 litres per person, we need 2000 MLD of water. Kaveri provides 1450 MLD everyday. Its the remaining people who depend on ground water who are in serious trouble.

There is 34 tmcft of water in Kaveri basin reservoirs and for next 5 months we need 8 tmcft at 1250 MLD rate we are using today. Not an alarming situation. But as usual everything is getting hyped due to complacency of authorities in not providing everyone with Kaveri water and people who thought water tanker status quo would satisfy needs in the long run.

We need to make sure supply of Kaveri water is ahead of population growth so that everyone gets the needed the water. The IT parks and huge apartment complexes in Eastern parts depend solely on tankers. I used to see continuous line of tankers coming in and going out even in good days.

Bengaluru needs to get an allotment from Kaveri for yearly needs which is now very meagre that is calculated based on its contribution to the river through rains. City is mostly drawing water from farming share and should get its own share.

Bengaluru is facing a severe water crisis now due to several factors, such as:
• Lack of rainfall has caused the water levels in the Cauvery River to drop. This shortage affects both drinking water and irrigation. Additionally, borewells in Bengaluru are drying up because of the lack of rain in recent months.
• High demand and low water supply have led to a shortfall of 1,680 million liters per day. The city receives around 1,450 million liters per day of water from the Cauvery, but more is needed to meet the needs of the growing population.
1. High prices and scarcity of water tankers cost north of Rs.2000 per tanker, which many residents and commercial establishments use as an alternative water source.
2. Most high-rises and societies advised residents to limit water usage due to scarcity.
3. Even my society in north Bengaluru has instructed us to use water sensibly.

4. A few high rises asked to use Disposable plates and wet wipes due to water shortage

Some interesting research on generating fresh water from moisture in air - very much applicable to places on the interior parts, away from coast. Although much work has happened in this area, this recent research is very close to the theoretical possible limit and promises to generate water 24 hours . In a country like ours where water scarcity is omnipresent and we have high humid climate, every drop of water can make a big difference.

Its from the same research group that worked on developing coating to prevent fogging on glasses (Face mask + sunglasses (or spectacles) : How to prevent the glass from fogging up?).

Another methodology to reduce water consumption - water atomizers. Easily fit into taps.

+1.

In the time that a shower fills up that 20 lts bucket (assuming the flow is normal and not too high), anybody should be able to complete a bath.

The discourse about wasting water with shower vs bucket, is applicable only for people who keep the shower on from start to finish. If we use it only when needed, then a shower is much more frugal than a bucket of water. In fact, fancy hand showers are even better, as they are much more efficient than pouring water with a mug.

I've tried this few years ago (not sure if the tech has drastically improved), but these clog within a week with hard water. If you don't clean with a special solution within a week then you need heavy acid bath to clear the scaling buildup. I've found that putting an extra valve (under the sink) to reduce the flow to a minimum is more manageable solution when dealing with hard water.
