Water Tank Selection: Size, Material, and Design Tips

Modern tanks come in plastic, steel, rubber bladder, and even rock-look designs. Choose by answering five questions:

1. Required capacity? (Typical home: 1,000–3,000 L.)
2. Best shape for site? (Round, slimline, underground, bladder.)
3. Above-ground or in-ground?
4. Roof catchment area available?
5. Pump size for delivery pressure?

Material Trends

• Polyethylene: any size/color, UV-stable, lightweight.
• Steel: evolving designs, traditional strength.
• Rubber bladder: flexible, fits under decks, in vehicles.
• Rock-mimic: blends in sensitive landscapes.

Research, consult qualified suppliers, and set a budget before buying.
