This research aims to increase the efficiency of artesian water pump systems by DMAIC method; A case study of Porthanklaivajasit Hospital, Chawang district, Nakhon Si Thammarat Province, which consists of determining the problems, measuring to determine the cause and gathering data, analyzing the problems and the causes for better work development, and controlling procedures. The result of experiment was compared before and after of the well water pumping system. The experimental results showed that it can increase the productivity of the groundwater pumping system by installing timers, automatic on-off relays, which reduce the time of the work process from 295.45 min to 256.95 min, it can be reduced to 38.5 min. Previous studies have shown that the groundwater pump works for 30.50 h and produces 15.19 cubic meters of water and after the improvement of the groundwater pumping system, the total working time was 11.50 h, the amount of obtained water was 16.11 cubic meters, which could reduce the time system for 19 h and increase the amount of groundwater by 0.92 cubic meters, respectively. Additionally, the cost of electricity and water can be reduced. The DMAIC analysis process can also be used as a guideline to increase productivity in other industries as well.
