Sendai Wastewater Utility acquired the first certification of ISO55001 in Japan at March 2014. ISO55001 is the international standard for asset management systems and was published in January 2014. During the process towards certification, the maturity assessment, internal audit and certification exam based on ISO55001 were all executed. It was possible, therefore, to compare the three methods, and recognize their strengths and weaknesses. The methods complement each other when implemented simultaneously.
