Calculations for Overhead Water tank | Building Construction

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
