In certain regions of the world, constant and organized water supply to households isn’t provided by the state or government.
This leaves owners of houses with no choice but to provide themselves with personal boreholes, water pumps, and disposal units. Some of us just prefer to have private water systems for unique reasons.
Personally, I use a 2,000-liter tank, which can last for around three days. And yes, it’s a rented apartment, the tank was pre-installed and it lasts for about a day and a half, meaning it’s quite short of what we require. That’s because we just don’t enjoy pumping water into a water tank frequently; it takes a lot of money.
So research was made for you on this subject, determining the selection of water storage tanks for each house.
Tanks traditionally have general sizes varying from 340 to 340,000 liters. Regardless, sizes beyond these can be customized.
The needed sizes for your specific homes can be determined by the type of structure (of housing unit), the number of individuals it is catered for (considering one individual consumes about 135 liters per day), and an average of a three-day use factor (i.e. the tank should be able to supply for three days without pumping to replace used water).
You can even consider the material of the tank. If you’re willing to find out more about the best tank materials for your water storage tank, visit the article here, and hope it helps you out.
Best Water Tank Sizes for Each Housing Structure
In choosing the best water tank sizes, here are the criteria with regards to the structure of housing:
Housing Sub-Units (450 to 1,000 Liters)
Housing sub-units typically exist for recreational purposes or to help supplement comfort by creating a home-like environment, in exercising basic daily rituals, even when you are away from the conventional house.
Examples of these include trailers, camping vans, tour buses, and treehouses.
In other words, it is a smaller house on wheels you move around with you when you are not in your real home. Such houses are required to have water supplies one way or another, no?
In most cases, storage tanks are pre-installed and their size required varies from 450 to 1,500 liters, considering that a number of 1 to 4 people occupy such at any given time.
A single person is said to consume a standard of about 140 liters per day, with other factors considered.
Therefore, the previously mentioned ranges are ideal for this form of housing.
Placement or positions of tanks vary with regard to company design or personal preference. That is, it’s either what they give you for price or what you customize it to be.
Bungalow/Cottage (2,000 to 3,500 Liters)
Bungalows and cottages are two of the smallest forms of conventional housing units you would find in the modern world today. They can be regarded as two of the traditional pioneers of small housing.
Although, with innovation, people can be very creative in constructing smaller housing units just like the ones we mentioned previously.
Bungalows and cottages are similar in some regards as they are quite distinctive in design, outlook, and heritage.
Both of them are low-profile types of housing originating partly from the intent of housing smaller families.
A bungalow exists as a simple structure of less complex designs and a direct roof over the ground floor, with complete walls holding it in place.
The cottage can be slightly complex; it is built with a system that allows for another floor above the ground floor. Hence it can potentially accommodate more people, a little more than the regular family.
The numbers are close, but bungalows and cottages can easily house about 4 to 7 people ideally, with tank sizes ranging from 2,000 to 3,000 liters.
Terrace/Detached House/Duplex (2,000 to 3,500 Liters)
These categories of housing are quite different in structures. With regards to its mass and capacity to house a specific number of people; they belong in the same bracket.
These houses, although large in size, typically do not contain more than what a bungalow or a cottage contains. It is just that those who live in the house happen to have more money at their disposal, or require more space within the house.
If a cohabitant range of 4 to 7 people is considered, the house needs a water tank with a water supply worth 2,000 to 3,500 liters on a 3-day span.
Flat/Apartment Houses (3,500 Liters per Flat)
Flats or apartments are known to be singular parts of a structural housing unit. They usually are conducive to living and offer basic amenities like in a typical home.
A full structural housing unit contains numerous flats/apartments at once for the purpose of either sales or rental.
Depending on its internal space, location, and access to basic amenities, flats can contain a range of 2 to 10 people, which in turn affects the required size of the tank for water supply.
On average, a singular flat will require a size of 3,500 liters for a 3-day life span before the tank is to be refilled.
The total water requirement for one flat is simply multiplied by the number of flats present to give the maximum amount of liters of the tank needed for the whole building.
Here is a table that shows the recommended water tank size in relation to the number of flats in a building.

|Recommended Water Tank Size (in Liters)
If preferred, tank sizes can be bought at once or can be shared into smaller same sizes to supply each flat separately or if you plan on managing or utilizing space. This will, however, attract an extra cost of running supplementary supply lines from different tanks.
For example, instead of buying in a 7,000-liter tank, you can purchase two of a 3,500-liter tank to supply each flat separately. Of course, this comes with an added cost and space in order to prevent friction between the two flats.
Mansion (20,000 to 30,000 Liters)
Mansions are more or less one of the elite forms of housing within this modern era. They can cover from 6,000 to 23,000 square feet of land size, depending on the personal preference of the owner and its design.
Mansions are naturally complex with a host of extra housing features such as landscapes, multiple bathrooms, wine-cellars / private bars, five-car garage, gas pump, sauna, etc.
Some of these features require water either for upkeep, maintenance, or personal use. This increases the average amount used by an individual that lives here.
According to research, 200 liters per person is the recommended amount that can be used with this particular condition.
A mansion can inhabit about 10 to 50 people. Therefore, the size of the tank required would ideally be within 20,000 to 30,000 liters with awater-holding limit of a minimum of three days.
