What is the cost of a liter of biocompatible water produced with the Melusine fountain of Aqua Dyn Auroville?
This is the question we asked ourselves and to which we have given a precise and detailed answer. We took into account: the investment cost of the machine, its maintenance, its water and electricity consumption compared to the price of bottled water.
For Aqua Dyn Auroville's Melusine fountain, at an average consumption of 6 liters per day in a 4-person household (1.5 liters of drinking water per day and per person), the cost per liter of biocompatible water produced, taking into account the investment, is 0.218€. Excluding the investment, the cost per liter of biocompatible water produced is 0.037€.
Investment over 5 years : 0,181€ / liter
Water : 0.008€ / liter
Electricity : 0.006€ / liter
Cartridges : 0,023€ / liter
------
Total : 0,218€ / liter
It is almost half the price of bottled spring water such as Montcalm. While avoiding the costs associated with the purchase of bottles (fuel, storage, handling, pollution) and a much better quality of water available.
Note: the more water you use, the lower the production cost per liter.
The Melusine fountain is capable of producing over 100 liters of biocompatible water per day.
Details of the calculations for a period of use of 5 years at a rate of 6 liters per day
