The regional water company (PDAM) Surakarta City is a regional company that serves drinking water needs for the people in Surakarta. In 2018, PDAM Surakarta City served 58871 customers and more than 5000 former customers. Illegal connections by former PDAM customers became one of the most dominant factors in the loss of commercial and non-physical water in PDAM Surakarta City. To reduce non-physical water leakage and improve services at PDAM Surakarta City, a study was conducted involving former PDAM customers with a total of 5000 respondents. The purpose of this study is to identify the water sources currently used by former PDAM customers and the reasons for the service discontinuation; identify the interest of former PDAM customers to reconnect; find indications of illegal connections by former customers of PDAM Surakarta City. A survey method was used with the mWater application and data analysis using SPSS. The results of the study explained the reasons for former PDAM customers to stop subscribing to the service because of the uncertainty of water flows, the poor water quality, the high water tariff, and the arrears of the customers. The former customers who are interested in reconnecting consist of 126 respondents. 2296 former customers who are demolished by invisible PDAM water lines, 84 respondents whose PDAM water meters are still installed, and 16 respondents there are former PDAM water line disconnections which are now connected to hoses/pipes, and as many as 500 respondents there are remnants of former PDAM demolition pipes. Based on the findings in the field, indications of illegal connections from 5000 respondents are strong indications as many as 5 respondents, moderate indications as many as 50 respondents, weak indications as many as 1125 respondents, and no indications as many as 3820 respondents. © Published under licence by IOP Publishing Ltd.
