Water losses is a problem that often occurs in PDAM (Perusahaan Daerah Air Minum), including PDAM Maja Tirta, Mojokerto City. Water meters at customer connections installed for a long time and have never been calibrated can decrease in accuracy, causing commercial water losses. This study starts with a literature study about water losses. It then collected secondary data from PDAM Maja Tirta Mojokerto City in the form of service maps, the number and address of customers, the volume of water input that enters the distribution system, the system output volume, and tariffs or prices water. An analysis can be done from the secondary data to determine the number and location of sampling using the method described in SNI 05-0666 of 1997. The primary data that will be taken is the accuracy of the customer's water meter measurements. From the study results, the level of commercial water loss due to the accuracy of the water meter was 8,52% from input system volume (total distributed water) or 148.160 m3. Control of commercial water losses can be done by periodically measuring the customer's water meter, replacing damaged water meter, and adding an input system water meter.
