Design of Overhead Water Tank | Design of RCC Structures
As per NBC (National Building Code, 2005) standards,
Water required per person per day = 150 litres
Drinking water = 4litres per person per day
Calculation for an overhead water tank for a 3 BHK Villa:
Let us assume the average family size = 5 persons in the house
Water required for daily chores per person per day as per NBC norms;
150 x 5 = 750 litres
Drinking water required:
4 x 5 = 20 litres
Total quantity of water required = 750+20 = 770 litres
Volume of water = 770/1000 = 0.77 cubic metres
