A general rule of thumb is to look at your roof area and average local rainfall. For a standard garden, a 1,000L to 2,500L tank is usually sufficient. For commercial use, we recommend a capacity that can store at least 18 days of your average daily water requirement.
While both collect rain, a harvesting tank is typically larger, made of thicker industrial-grade plastic, and often features specialized 'calmed inlets' and overflow siphons to improve water quality and allow for pump integration.
Yes, a filter is essential. It prevents leaves, moss, and debris from entering the tank, which keeps the water clear and prevents the buildup of sludge that can smell or damage pumps.
Yes, but this requires a more advanced 'Header Tank' or 'Direct Feed' system with a pump and a mains-water backup to ensure you still have water when the tank is empty. It also requires dedicated pipework clearly marked as non-potable.
Our tanks are made from opaque, UV-stabilized plastic which blocks sunlight. This prevents algae growth. Combined with a good pre-tank filter, the water will stay fresh and clean for long periods.
The tank must be placed on a flat, level, and fully supported base—usually a 100mm-150mm thick concrete pad. This is vital because a full 5,000L tank weighs 5 tonnes; an uneven base could cause the tank to split.
Absolutely. You can 'daisy-chain' tanks at the base using a linking kit. This allows them to fill and empty at the same level, effectively increasing your total storage capacity.
If you only want to fill a watering can, a gravity-fed tap is fine. However, if you want to use a hosepipe, sprinkler, or supply water to a building, you will need a submersible or external surface pump.
