> Rainwater harvesting Calculator
This rainwater harvesting calculator (operational since 2009 and commonly called a tankulator) works out what your expected rainfall collection capacity should be over a given year, along with your minimal tank size to have constant water given an average monthly demand.
Remember, the values calculated here should be taken as a working guide, it does not take into account other effects (such as drought conditions) and how complete the source data coverage is.
