paint has begun to fade. Home / Box AWLR (automatic Water Level Recorder) SESAME must be repaired. c. The condition of the ladder that is on the wall inside the spillway looks rusty. d. The wet location or seepage trace is found in joint G0. The concrete connection is observed by 3 (three) Dimension Joint Apparatus. The condition of the former leakage monitoring tool in joint 0 that is Rive Droite (RD) and Rive Gauche (RG) still looks stagnant due to drainage of seepage see page clogged, If will be measured discharge leakage RD and RG must first pumped. Therefore the measurements of the RD and RG leakage discharges are now done in a new place through two pipes connected directly to the directional pipe steering join 0. The sliding benchmark in the Access Gallery is mostly without a protective cover. e. In the ceiling space re-cavitation occurs on the concrete wall that has been done with the addition of using cement. Corrosion section contained in the cooling pipe casing on the staircase entering the ceiling has not been repaired. f. In the left sump Pit found cracks in the concrete wall, concrete and concrete floor joints drainage see page (sump pit) left, so the concrete floor is relatively slippery when skipped. g. The condition of the right collecting drum space (sump pit) mostly cavitation, moist and wet. The wet location is found almost in all the right (sump pit) areas, so the concrete floor is relatively slippery when skipped. h. The condition of the bouchon, the tap (gate valve) to open the waterway has been consumed by corrosion. Condition of concrete wall, and concrete connection experience cavitation, moist and wet. Wet locations and puddles are found only on the side of the baton wall around the entrance hall. i. The intake room of the riva pump is inundated about 2 meters deep and needs to be addressed immediately because of mild corrosion. j. The old cracks in the majority of concrete are found in the interior walls of the circle and a small part is found in the exterior circle but the condition does not change significantly. k. The old vapor that forms the cavity to the right of the tailrace (about 20 m to the left of OW IC748) has been repaired by means of the extraction and compaction of the material. l. Elevators contained in the access gallery is not working and severely damaged (high corrosive) as well as around the elevator door area often leaks. The protective cable cover (concrete plate) at the top of the tower is partially cracked. 4. SADDLE DAM INSPECTION 4.1. PASIR GOMBONG BARAT SADDLE DAM 963
