#### 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

#### Dimensions for the overhead water tank:

Length = 1.2m

Breadth = 0.6m

Depth = 1.1m

Total Volume = 1.2×0.6×1.1 = 0.792 cubic metres

i need detail estimate and drg of 50,75 ,300 and 500 cum overhead tank .

1000 litre water tank can be fitted at roof of house that is made by brick column and brick wall no RCC…pls tell me….

Yes, can be done. You can go for a tank size (internal dimensions) of 3′ x 5′, and a height of 4′. It would give you a capacity of 1500 liters. Use 9″ thick walls. Don’t forget waterproofing.

the overhead water tank capacity required for using 18 houses.

Hi,

We have 21 flats in a building and we all want to set water tank 500 lit/each because of water issue. Our terrace area is 5000 sq feet. Is it OK if we fit water tank on terrace. Can it be problem to building structure in future

Do you mean 21 water tanks 500l each?

Plan for dm water tank

Calculations for Overhead Water tank

Bill of Materials

Can a hole be drilled in adjacent concrete water tanks for water balancing? Size of the two tanks are 3000 m3 and 6000m3. Surface area of the common separating wall is 2 meter wide and 3 meter deep.

I want the formula for calculation of Concrete quantity for overhead water tank dome..so please give me.

Alternative method :

1 cubic foot = 28.3168 litres.

Therefore to store 770 litres of water we need (770/28.3168=)27.192 Cft tank space.

how to take dimension of the overhead water tank

(L*B*D)

it is very useful for basic design concepts need some more clarity

i want information about to construct a sump&over head tanks in rural water supply scheme.tell me if any latest techniques to construct a OHBR.

Pls tell me how I know the material used in rcc over head tank is how much. (With staging).formula that used to calculate estimated cost value

sir i want to know the details and type design of over head balancing reservoir of different capacities and different staging

Please tell me how to construct watertank on my RCC terrace.

need the full design of over head tank

Building an overhead water tank does need a lot of calculation and many things to be thought about to give rise to an efficient construction. It would be better to give a platform built of steel and the required support from the base would do the work but then too there are certain factors that would vary with respect to place and a professional would be the best to guide here.
