- "The water that rich people drink, and the main reason why there are now entire continents of plastic bottles floating in the ocean."
- ―Liberty City National Exchange description.
Rainé water coolers can be found in various interiors, such as the office of Roman's taxi firm in Hove Beach, Broker, the Grotti Showroom in Middle Park East, Algonquin, the Liberty City Swingers offices in the MeTV Building in Star Junction, Algonquin, hospitals and much more. Rainé bottled water is advertised on billboards across Liberty City. The company logo is found on some Steed trucks. Rainé returns in GTA V, sponsoring a magazine most likely called "Tennis Beach".
The company's name and motto ("L'eau du ciel", French for "The water of the sky") implies that they sell bottled rain water. The vending machines in GTA V also say "may contain acid", which may be a reference to acid rain, a common pollutant found in rain which may occur in large metropolitan areas. The Acid reference could also be to Carbonic Acid which occurs when Carbon Dioxide mixes with water in the atmosphere.
