Choosing the best tank size is crucial for avoiding water shortages or unnecessary expenses.
Ideal Water Tank Size Based on Family Size
1–2 members: 500–700 liters
3–4 members: 1000 liters
5–6 members: 1500–2000 liters
Large families or villas: 2000+ liters
How to Calculate Water Usage
On average, one person uses 135–150 liters of water per day in India (as per urban standards). Multiply this by your family size to estimate your requirement.
Always choose a tank slightly larger than your requirement to handle water cuts or irregular supply.
