Assuming a cost of AED 1.5/Liter to pump and distribute water in a municipal supply system that loses (P) of its water because of leaks, how much money is wasted annually for a city of (X) million people with a per capita demand of 300 Liters/day?
where, X = 21.0 millions P = 2%
Detailed answer is as follows
First let us calculate the water requirement per day based on the given date.
Total demand/day
Population =21000,000
Per capita demand = 300 litres/day
Total demand =21000,000 x 300
=6300,000,000 litres
Wastage per day
Percentage of wastage is 2%
Per day wastage in litres = (2/100) x 6300000000
=126,000,000 litres
Money wasted per year
Money wasted per year =wastage per day x 360 x rate per liter
=126,000,000 x 360 x 1.5
=AED 68,040,000,000
