Specs

Choosing the Right Size

Selecting the correct tank size depends on your garden size, water usage, and rainfall levels. A larger tank will maximise water capture and reduce reliance on mains water during dry periods, while smaller capacities are ideal for light garden use.

  • 1,800–2,600 litres: Suitable for small gardens, occasional hose use, and general outdoor cleaning.
  • 3,400–4,400 litres: Recommended for medium gardens, regular watering, and small irrigation systems.
  • 5,200–6,800 litres: Ideal for large gardens, landscapers, or users running multiple hose outlets.
  • 8,400–10,000 litres: Best suited for estates, large properties, or small commercial and horticultural applications.

If in doubt, it's advisable to choose the larger option within your space and budget, as rainwater capture efficiency increases with storage capacity and reduces overflow losses during heavy rainfall.
