To choose the correct water tank size for everyday household use, you need to consider household size, water usage, rainfall availability, and how the tank will be used.
As a general guideline:
1–2 people: 1,000L – 2,500L
3–4 people: 2,500L – 5,000L
5+ people: 5,000L – 10,000L or larger
If the tank is used as a backup supply (for municipal outages), a smaller tank may be sufficient.
If the tank is used for rainwater harvesting to supply toilets, laundry, or garden irrigation, a larger tank is recommended to store enough water between rainfall events.
Other factors to consider include:
Available space for installation
Roof size and rainwater catchment area
Whether a pump and filtration system will be installed
For the best results, RotoTank recommends selecting a tank that meets both daily usage needs and future water security requirements.
