%X Water leakage from distribution buried pipes is one of the extreme threats to water resources controlling. It represents severe negative impacts on the environment. Hence, it is highly needed to find out leakage sites to solve such environmental and development problem. The pipe under consideration is made from iron with a diameter of 250 mm. Hence, the magnetic method can be used to delineate the location of the pipe. TDEM method is hence used to conjunction magnetic gradiometer method to find out the position along the buried iron pipe. Magnetic gradiometer conducted at three long profiles parallel to the pipe. TDEM, on the other hand, is carried out at four profiles across the pipe. The result of gradiometer clearly mapped the extension of the pipe. In addition, a negative anomaly is observed starting at the leakage position. TDEM which was conducted using single loop array of side-length of 10 m, delineate two low resistivity anomalies. The first one is located near the end of the pipe, whereas the other is located at the leakage position. The first anomaly extends to deeper depths (possibly greater than 30 m) and can be interpreted as a possible accumulation of hot water. © 2017 American Scientific Publishers All rights reserved.
