Mumbai’s Chhattrapati Shivaji International Airport recently adopted a strategy that reduces the use of water in its urinals and the cleaning of floors, according to an article on the DNA India website.

Airport authorities said that they are using a mixture of microbes to do away with using water in its men's urinals and in mopping its 1,400 acres of floor space.

The bacteria convert the ammonia generated by uric acid accumulation to nitrogen, as soon as the toilet is used.

Unlike conventional cleaning methods which require regular touch-ups, the bacteria in the mixture work round the clock, the article said.
