Choosing the right size of underground water tank is important to make sure your household always has enough water. Whether you use water for drinking, washing, gardening, or other needs, having a properly sized tank saves water, space, and money.
Here’s a simple guide to help homeowners decide the right underground water tank dimensions based on daily water use, family size, and space available.
1. Know Your Daily Water Usage
Start by understanding how much water your family uses each day. On average:
- A single person uses 135-150 liters per day.
- A family of 4 may use around 500-600 liters daily.
Multiply your daily water usage by the number of days you want to store water for. For example, if you want to store water for 5 days and use 600 liters per day:
600 x 5 = 3,000 liters
You’ll need a tank with at least 3,000-liter underground water tank dimensions.
2. Consider Space Availability
The space available in your yard or basement will affect what size of tank you can install. If space is tight, you might need a deeper tank with a smaller surface area. If you have more room, you can go with a wide and shallow tank.
Always check the area where you plan to install the tank. Keep some space for installation and future tank cleaning services like Underground Water Tank Cleaning.
3. Choose the Right Shape and Material
Underground water tanks come in different shapes—cylindrical, rectangular, and square. Shapes affect underground water tank dimensions, and each one fits differently depending on the land.
Popular materials include:
- RCC (Reinforced Cement Concrete) – strong and long-lasting
- Plastic/Polyethylene – easy to install, good for small families
- FRP (Fiber-Reinforced Plastic) – lightweight and durable
Make sure your material matches your water needs and location.
4. Plan for Future Use
Think long-term. If your water usage might increase in the future—like adding more people to the house or setting up a garden—go for a slightly bigger size of underground water tank.
It’s better to have extra capacity than run short during high-demand days.
5. Talk to Experts
Every house is different. It’s always good to consult a professional before installing. They can measure your space, check soil type, and suggest the perfect underground water tank dimensions.
