Answer 1

• Toilet flush: 126 litres (two flushes per day; the rest of the time use grey water)
• Washing hands: 25.2 litres (12 times per day, on average)
• Brushing teeth: 5.6 litres (twice per day)
• Bath: 50 litres (1 half-full bath per week, which includes water for rinsing hair. Washing your hair once a week may be less than you (or your hair type) can tolerate but it’s perfectly hygienic.)
• Sponge bath: 1.8 litres (six times a week. Sponge baths are also hygienic if done properly: it’s how patients are washed in hospital. Make sure you keep your washcloths/sponges scrupulously clean, and use a fresh one every time you wash.)
• Handwashing dishes: 63 litres (3.5 sink-loads per week)
• Dishwasher: 29 litres (one load per week)
• Washing machine: 112.5 litres (1.5 loads per week)
• Cooking: 7 litres (average one litre per day)
• Water for tea/coffee: 4.2 litres (average three cups per day)
• Refilling pet water bowl: 6.3 litres (three cat bowls per day)
• Dripping tap: 35 litres

TOTAL = 465.6 litres per week OR 66.5 litres per day

Hope it helps you.
