How many liters of water can be saved by an average family with a dual flush toilet?
Traditional Flushing System causes approximately 30% of daily water wastage. To minimize this water wastage, modern systems come with a dual flush configurations.
A single flush would be using somewhere between 6L to 13L of water in the traditional system. Compared to a single flush system, a dual flush system has two buttons. One button for light flush and the other for solid flush. The light flush uses approximately 1.5L per flush and the solid flush uses approximately 3.5L per flush.
Based on this a single family can end up saving approximately 60% water or 32L water every day.
