October is the month in the water calendar when we switch from a time of 'resources loss' (when we use more water than rain falls from the sky) to a time of recharge. As the days get shorter and the weather wetter, in hydrological terms, it’s a brand new year.
The hydrological new year occurs on 1 October (in the Northern Hemisphere) and it’s the point when the hydrological cycle is in balance. Rain that falls after 1 October recharges our aquifers, so a wet winter is essential for securing our water supplies.
