Rainé water coolers can be found in various interiors, such as the office of Roman's taxi firm in Hove Beach, Broker, the Grotti Dealership 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.
