How to Calculate Water Tank Capacity and Size for a Building in Litres:
Wondering “How to Calculate Rectangular Water Tank Size and Capacity in Liters”? It’s a good question, because the answers vary depending on how much water you use! Obviously, the bigger your water tank is, the more water you can store in it. Some of the things you should keep in mind when decided how big your rainwater tank should be include: Water Tank Capacity in Litres
How Much Water Do You Need?
On average a fourperson family consumes around 600 Litres per day, which comes to 120 to 200 Litres per person. But the value of the minimum water requirement has been retained as 135 Litres per head per day as Per IS Code. Water Tank Sizes Calculator
 50% – Outdoor use (car washing, hosing driveways, garden use)
 17% – Showers
 13% – Toilets
 11.5% – Laundry how to calculate sump capacity
 8.5% – Other (includes drinking) Water Tank Sizes Calculator
However, what sized water tank you need will depend on how you’re planning to use your tank water. It might surprise you to find that the vast majority of the water your household uses is probably outside, or in your shower, toilet or laundry. While all of the water that comes from the main water supply and into your home is treated and can be safely consumed by your family, most of it doesn’t actually have to be; basically, you don’t have to water your garden or wash your car with drinking water. Rectangular Water Tanks
Water Tank Capacity Requirement:
Be it underground or overhead water tanks the capacity calculation is essential. If you build a tank with huge capacity than the required quantity, you may not need to worry about the storage issue, but you willwaste a Lot of money in other ways. What happens if you buid a huge tank than your actual requirement? how to calculate sump capacity
 Every time there will be some water Leftover. Storing water for a Long time will make it contaminated now the old water contamination will get mixed with the new one. There are a so health hazards.
 Second thing, it needs to be maintained regularly. With a big tank, It becomes a headache for you. If it is underground, then you need to hire manpower often to clean it property.
To avoid such conditions you need to calculate your average daily requirement along with your scheduled water refill. According to that, you can buid an optimum water tank size with economic benefits.
Water Tank Capacity Calculation Formula:
According to IS Code 1172 (1993). the value of the minimum water requirement has been retained as 135 Litres per head per day. It varies based on the building types. Breakup of the IS assumptions:
 Drinking – 5 litres
 Cooking – 5 litres
 Bathing & Toilet – 85 litres
 Washing Clothes & Utensils – 30 litres
 Cleaning House – 10 litres
So we can calculate the capicity of 1 rectangular Water Tank as per the following formula:
Total Capacity of Water Storage Tank = (Number of persons X Minimum Wetter requirement) / 1000
Example Calculation:
Assume we need to calculate the size of a water tank for a residential building with 8 persons. 5x5x5 water tank capacity
Minimum Water Requirement = Number of persons X Minimum Wetter requirement = 8 X 135 Litres = 1080 Litres 5x5x5 water tank capacity
We know, 1 m^{3} = 1000 litres of water.
So the required storage apacity or volume for 1080 Litres = 1.08 Cubic Metre.
Now we have calculated the volume of water reqrement.
Overhead or Underground Water Tank? – It is up to you. Normally an overhead tank requires more strong support to build which affects your budget. Underground tanks, on the other hand,do not need any kind of strong support since we place it on the ground.
Water Tank Size Calculation Formula:
Area of Tank = Capicity of Water Requirement / Assume depth
L x B = Area of Tank
Take Length as 2 Times of B, so L= 2B
2B x B = Area of Tank
2B^{2} = ank) / 2]
There for L = 2BArea of Tank
B^{2} = (Area of Tank) / 2
B = Sqrt [(Area of T
Example Calculation:
For a typical family (5 members),
Total water requirement is 135 litres x 5 = 675 litres per day.
We all know Volume of water formula as 1 m^{3} = 1000 litres of water.
In order to get the size of the water tank, you need to mention at least one dimension (Length, Width or Depth of the water tank).
If you are planning to construct a water tank in car parking area there may be some restriction on length.
That’s the reason why we are planning to construct the underground water tank while foundation work.
From the above, volume of water formula, Volume of Water Tank
1 m^{3} = 1000 litres
Our requirement is 675 litres,
Therefore, 675 litres = 0.675 m^{3}
Assuming our water tank depth as 0.6 m
Area of Tank = 0.675 / 0.6 = 1.125 m^{2}
L x B = 1.125 m^{2}
Take Length as 2 Times of B, (L = 2B)
Note: you can also replace your input if you know the length
2B x B = 1.125 m^{2}
B^{2} = 1.125 / 2
B^{2} = 0.5625
B = Sqrt (0.5625)
B = 0.75 m
Therefore, L = 2B
L = 2 x 0.75
L = 1.50 m
So, for 675 Liters Rectangular Water Tank Size, L= 1.50 m, B = 0.75 m and D = 0.6 m

FAQs:
Q. How do I calculate my water tank capacity?
Water Tank Capacity Calculation Formula:
Total Capacity of Water Storage Tank = (Number of persons X Minimum Wetter requirement) / 1000
Q. How do I calculate my water tank size?
Water Tank Size Calculation Formula: 1 lakh litre water tank size
Area of Tank = Capicity of Water Requirement / Assume depth
L x B = Area of Tank Take Length as 2 Times of B, so L= 2B
2B x B = Area of Tank underground water tank size in feet
2B^{2} = Area of Tank
B^{2} = (Area of Tank) / 2 1 lakh litre water tank size
B = Sqrt [(Area of Tank) / 2]
There for L = 2B underground water tank size in feet
Q. How do I calculate tank volume in Litres?
Dividing the volume (in cubic centimeters) of the shape by 1,000 will give you the volume in liters (L). . So, a fish tank that is 40.64 cm long, 25.4 cm wide, and 20.32 tall has a volume of 20.975 L.
Q. What is the Minimum Requirement of Water Per Person?
According to IS Code 1172 (1993). the value of the minimum water requirement has been retained as 135 Litres per head per day. It varies based on the building types.
Q. How to Calculate the Consumption of Water Per Person?
Minimum Water Consumption is 135 Liter per day per person as per the following consumption rules:
 Drinking – 5 litres average rv water tank size
 Cooking – 5 litres
 Bathing & Toilet – 85 litres
 Washing Clothes & Utensils – 30 litres
 Cleaning House – 10 litres average rv water tank size
