Improved Reliability of Waste Water Pump
This is a case study for a chronic waste water unit pumps failures. The impact of the failures were severe due to the significant cost of maintenance (130K USD on average) which was taking place twice a year. The pump design was re-evaluated, and after thorough market research, a cheap solution was found for a pump upgrade with a project cost that is less than 50% of the existing maintenance cost (Capital Project cost was 40K USD). After 15 months of operation, there has been zero breakdown/corrective maintenance cost. The yearly maintenance cost was eliminated down to zero (excluding the lubrication cost).
