Human necessity toward consumable drinking water increases along with population growth. People nowadays have a hard time obtaining clean water because of polluted river. To meet daily necessity of drinking water, a lot of industries open drinking water business, particularly refill drinking water facility (DAMIU). The utilization of refill drinking water facility has its own hazardous risk because of the doubtful quality, moreover if the customers aren't paying attention towards the security and hygiene. This study used FMEA (Failure Mode Effect and Analysis) to determine the priority of failure incident in refill drinking water treatment process. This FMEA method was used because FMEA has advantage over other method in term of being more feasible and effective for operational improvement while being able to analyze risk in bigger and more complex scale. To determine the failure, we first did risk identification which contained failures information obtained from interview, quality test, and direct observation. Failure causes risk happened in refill drinking water facilities were analyzed using Fishbone method. The location of the study was in Rungkut District, Surabaya. The parameters used were turbidity, TDS, pH, and Total Coliform. Obtained risk should had a value to be measured and determined for the handling priority and to find improvement effort. The measurement value was called as RPN (Risk Priority Number) which was the multiply value of severity, occurrence, and detection. Based on analysis result using fishbone method there were 4 factors which caused failure for total coliform parameter. Then, it was analyzed using FMEA method, and it was found that failure happened within 3 highest priority, which was UV system contact duration, ozone system contact duration, and disinfection tool replacement and maintenance.
