Refill water is one important element in filling the increasing drinking water demand. The price offered by refill water depot is significantly lower than packaged water, however, its quality does not meet the standards, and therefore it will potentially affect people’s health. This risk surfaces if refill water depot installation can’t treat raw water as well as the environment surrounding properly. Thus, identification to refill water production failure cause is needed to minimize the possibility of failure happening. Identification and risk analysis processes are based on risk management concept by using Failure Mode and Effect Analysis (FMEA). Failure cause identification is done using fishbone diagram to find the root of the problem causing the failure. The root of the failure will then be given score to determine the biggest risk stated in Risk Priority Number (RPN). RPN value is obtained through multiplying severity, occurrence, and detection. The biggest failure cause in refill water depot is in the disinfection technology used, which is the replacing and contact duration of regulation regarding refill water also causes failure in refill water production process.
