Projected Water Savings

• Current Usage: The current water usage per washing cycle is 100 litres, with 15 cycles per day, resulting in a daily
consumption of 1,500 litres.

• Projected Reduction: Implementing the proposed system is estimated to save approximately 324 cubic meters (m³) of
water annually, achieved through water reuse and recycling.

• Monthly Saving Calculation: Water usage per month after implementation: 45,000−18,000 = 27,000 litres.

• Annual Saving Calculation: Water saving per year: 27,000 × 12 = 324,000 litres, equivalent to 324m³.

Environmental Impact

• C02 Emission Savings: The total annual C02 emission savings from the water conservation efforts are estimated at 463.32
kg with the proposed implementation as shown in Table 3.
