Mad Maths: Water Wastage

The wash-basin tap in my house is a very tricky apparatus. It stops water flow completely only at a particular position. Screwing it beyond that opens the tap in full flow again. I know its a washer problem, but it got me thinking, how much water could be dripping down the drain all over the world.

Assumption:
1 Drop of water has a volume of 1 mm³
6 billion people in the world
3 billion people living in proper houses with taps.
5 members in every family on an average
1 tap in every 3 families leaks, and lastly,
1 drop of water, drips every 6 seconds from the leaking tap.

Calculation:
No of families = 3,000,000,000 / 5 = 600,000,000 (600 million)
No of leaking taps = 600,000,000 / 3 = 200,000,000 (200 million)
No of drops wasted every 6 secs = 200 million drops
No of drops wasted per minute = 2 billion

Volume of water wasted per minute = 2 billion mm³

1 million mm³ = 1 litre
So, 2000 litres of water wasted per minute.

2000 x 14440 lites per day = 2,880,000 litres.

2.88 million litres of water wasted per day!!

Most of our tap water is drinkable. So if u compare it with bottled water prices, then Bisleri water costs Rs.10 per 1 Litre.

So in effect, the world literally pours 28.8 million rupees down the drain.
(28.8 million rupees, is approximately 650,000 USD).

That's a huge waste don't you think??? Gotta get the washer fixed ASAP!!

Yes this sad animation is indeed made by me. :(
