1 mm of rain on 1 m² of roof gives 1 litre (YourHome). We count 80% to allow for the first flush and overflow, our assumption. The 60 L/day toilet and laundry figure is an estimate; 247 L/day is the NSW BASIX benchmark (source). For a daily simulation use Renew's Tankulator.

Pad size

Material volume

Load when full

5.0 t

Compacted sand or crusher dust 75 to 100 mm with edging, or a 75 to 100 mm concrete pad.

Rule: Coerco installation guide. 1 litre of water weighs 1 kg. Order 10 to 15% extra material for compaction, our assumption.

Static water required

10,000 L

Material

Concrete or metal, above ground

Fittings

64 mm CFA 3 thread per inch male coupling, gravity feed, CFA access

Placement

Roll it in

• ok Path width 3 m vs 2.86 m needed to roll the tank on its side
• ok Clearance 5 m vs 4.08 m tank diameter plus margin
• ok Slope 5% (rolling over 10% is risky)
• ok Distance 25 m (over 60 m means a long roll)

Helpers to have on site

2+

Weight empty, approx.

470 kg

Drivers need able-bodied helpers and will not unload without safe access (ASC). A crane is at the buyer's expense (Bushmans). Put about 25 mm of water in an empty tank to stop it blowing away (Bushmans). The width, slope, distance, helper and empty weight thresholds are our rules of thumb.
