We operate pumps, monitor water distribution operation at service reservoirs and maintain equipment and facilities.

The pumping stations operate and monitor pumps and reservoirs based on the water supply operation guidelines provided by Water Supply Operation Center of Bureau of Waterworks to transmit and distribute water. Based on the guidelines, we also operate and monitor the booster pump stations.
