How to Choose the Right Water Tank Size for Home

Right Home Water Tank Size

Once upon a time, people took water from the ground. They use a bucket to take water into the ground. People also started digging individual borewells in their homes for fresh water. So they can pump the handle manually whenever they require water. After that, they dug deeper borewells, recycled river water, and pumped that water to people’s homes. So now people need to store this water for later household use because this water is used in the morning and evening.

Water storage tanks are made for this purpose. They are made with plastic, steel, concrete, and fiber. You can install a domestic water tank on the ground, rooftop, or backward. They are connected to the main water supply to your home. The water tank’s main purpose is to provide water 24 hours a day.

How Do You Choose the Right Water Storage Tank Size for Your Home?

Domestic water tanks come in various sizes, shapes, and materials. Water tanks come in various shapes, including rectangular, circular, cylindrical, slimline, and oval, each designed to meet specific spatial and structural requirements. Water tanks come in various sizes, from small 300-liter models for homes to massive 5000-liter vessels for home and industrial use, ensuring a fit for every need.

You can consider the following things before choosing a household water tank size:

Family members

The small water tank is best for a small family, and the bigger tank is for a larger family. A general guideline is to estimate about 50–75 gallons per person per day for bathing, toileting, handwashing, and drinking. Most water is spent on dishwashing in the kitchen, laundry, bathroom, sanitation, gardening, and washing. It is also extra water usage from personal use. So the following is the average water tank size chart, including all household requirements.

  • A 500-liter water tank will be enough for a 5-member family per day.
  • A 750-liter water tank will be enough for an eight-member family.
  • A 1000-liter water tank will be enough for a 10-member family.
  • A 1500-liter water tank will be for a joint family.

If you don’t waste water, the above-sized water tank will be a great fit for your house. Here’s a basic water usage calculation based on the number of family members:

  1. For a family of two: approximately 100–150 gallons per day.
  2. For a family of three: approximately 150–225 gallons per day.
  3. For a family of four: approximately 200–300 gallons per day.
  4. For a family of five: approximately 250–375 gallons per day.
  5. For a family of six: approximately 300–450 gallons per day.

Installation Location

The location of the water tank installation also matters. Nobody likes to put more burden on wooden terraces and metal roofs. Small-size water tanks are best for roofing and shelves. Larger tanks can be installed on the ground and underground. Plastic water tanks are best for home use because they are lightweight, cost-effective, and rust-proof.

Availability of Water

If your area faces frequent water shortages or if you are planning to use the tank for rainwater harvesting, consider a larger tank to ensure a sufficient supply during dry periods. Many people live where water supplies come in the morning, so they have to store water for the whole day and night. Smaller water tanks are sufficient for frequent water supply areas.

Shape and Maintenance

Water tanks come in different shapes and colors. The shape can affect the placement and space it occupies, while the color can influence the water temperature (black absorbs heat, white keeps water cool, and blue creates a visual connection). Spherical, paraboloid, square cylindrical, and slimline water tanks sydney shapes are more popular among the homeowners. Also, consider the ease of cleaning and maintenance. You should clean the home water tank at least once a year. Some materials may be easier to repair and clean than others.
