The increasing demand for high-capacity water tanks as a result of prolonged droughts and water scarcity in certain regions
Why are people choosing larger water tanks? Because supply is less predictable. When rainfall is uneven or municipal supply is interrupted, a larger tank acts as a buffer, so daily life isn’t disrupted when the taps run dry. Even in a high-rainfall state like Kerala, dry-season shortages are a familiar problem.
What’s driving the shift
- Irregular supply — storing more when water is available means less stress when it isn’t.
- Larger households and multi-storey buildings — more people drawing from one source.
- Planning ahead — many families now size their storage for several days of use, not just one.
How to decide on a capacity
Estimate daily water use per person, multiply by the number of people in your household, and then decide how many days of backup you want. Also consider where the tank will sit: roof load and available space matter as much as litres.
Options at Goodwill
Our 3-layer white tanks are available across eight capacities, from 310 up to 5000 litres, with UV-resistant outer layers for long-term overhead installation. For larger storage without adding roof load, an underground sump tank is another option.
FAQ
What size water tank does a family need? It depends on household size and how many days of backup you want. Multiply daily use per person by the number of people, then by the days of storage you’d like.
Is a bigger tank always better? Not necessarily. A tank much larger than you need can hold water for too long, and it adds weight and cost. Choose for your real usage plus a sensible buffer.
