IndiGo successfully tested a new water supply faucet on 200 flights, reducing water consumption by 5.4 liters per hour. With an average duration of “test” 138 minutes of flights, the carrier saved 12.42 liters of water per flight.
IndiGo's current schedule includes 1,500 daily flights with an average flight duration of 98 minutes. Thus, the new unit will reduce water consumption by 8.82 liters per flight, for a total of 13,230 liters of savings per day.
According to a company press release, this modification will also solve the problem of water limitation by weight on long flights. Less liquid on board, i.e. less overall weight, will help save fuel during flights, reducing carbon dioxide emissions by 930.75 kg CO2/m3 per year.
IndiGo — the first airline in the world to make changes to save water on board.
