34 liter toilet flush

34 liters is approximately the average consumption per person per day for toilet flushing.

By the way, in most cases this is drinking water, and the worst toilets require up to 14 liters per flush. Today, between 3 and 6 liters is normal. Perhaps you should consider upgrading.
