A medium sized commercial building with 20 taps can save Rs. 3636 or 8080 glasses of water per day.
Assume each of the 20 taps is being used for 20 min a day and discharge around 12 LPM at 60 psi.
Total water consumption with ordinary manual or sensor faucets = 20 * 20 * 12 = 4800 Liters / Day.
Total water consumption with GreenSense Faucets = 20 * 20 * 1.9 = 760 Liters/ Day.
Total saving in water consumption = (4800-760) = 4040 Liters / Day.
Total reduction in water consumption = 85%

* Calculations are done using applicable water, sewerage and electricity charges for commercial buildings of Rs. 30/ 1000 liters of water usage.
*Water Pressure of 60 psi is used for calculations as it is internationally accepted standard for flow rate measurements and closer to the realistic water pressure in buildings.
