	Abstract:	? RAS companies, researchers and consultants all over the world were surveyed. ? Poor system designs, water quality issues and mechanical problems are the main constraints. ? 50% of the surveyed companies have been rebuilt or redesigned due to RAS system’s failure. ? More than 8 years are needed to get back initial investment. ? In the future, information platforms, their availability and specialized education will be required.
