Water audit of our household: 127 litres per person per day, down from 210 at year start. Changes: 4-minute shower timer, greywater reuse for toilet flushing, rainwater collection for garden, fixed a dripping tap wasting 15 litres/day. Water scarcity affects 2 billion people today. Treating water as precious costs nothing and changes everything. #WaterConservation #SustainableLiving #WaterSecurity
