Mobile Rain Water Tank Calculator
Smart WaterMark has developed Australia’s first mobile rain tank calculator – iSaveH2O - available as a free download from iTunes.
The application is designed to help people discover how much water they can save and what size rain tank they need, and can be used when out in the field, or at point of purchase/consultation.
The iSaveH2O application is based on the online calculator available through smartwatermark.org. Behind the simple-to-use interface is a two gigabite Bureau Of Meteorology database including daily rainfall, evaporation and temperature data for the whole of Australia for the last 10 years.
