The one of a problem in PDAM is the high rate of water loss caused by pipeline leakage. Pipeline leakage is an important issue as resulting in financial losses, for both PDAM (water provider) and customers. Based on a previous study of, the area that allows the greatest pipe leakage such as Geledug-Leuwiliang and Cibungbulang-Ciampea, the reason is a complex volcanic rocks formation. Then this study has to continue by forecasting water loss per month up to 2017 to look at the frequency of water loss for immediate repair in handling pipeline leakage. Predicting to be done using ANFIS method and then it will test again with Backpropagation to check the error rate so that the data will be more accurate; where is the area in this study is Geledug-Leuwiliang (greatest pipeline leakage). The result is most likely due to visible leaks such as crack pipe caused by complex volcanic rocks formation (31.8% with error rate 1%). Therefore the effort made is to replace the leaky pipes which then do further study on the material used by the tube that is following the pipe area that planted.
