Thread: Hut tank size

@Remmodel7 how much storage you need depends on partially on how often it rains and roof catchment area, but mostly on often and how you're using the hut.
2 personal examples.
At our bach we have a 2000L tank. At times we (wife & I) use it for several weeks at a time. Drinking, washing dishes, shower. Roof catchment approx 30m2. Annual rain fall in the area ~700mm. Can be periods of several weeks with no rain. We need to be careful how we use the water but we have never run out, however have come close at times.
Conversely at our house have 55000L. Roof 250m2, annual rain ~1200-1700mm. Dishwasher, washing machine, etc etc. Very different than bach with many times the catchment area and storage, plus double the rainfall, but we still have come close to running out at times.

We have a large 4 br house but unfortunately being 2 storey the catchment is half a single level house.
