In a square compound with high security fencing (3 strands of barbed wire) 15 yards east of a track running south from the end of Glenmallie Road. There is a new road down the new Water Treatment site but the ROC post and its compound cannot be seen from it and no path to it. Best way to find is with a GPS (and machete!)
OPEN All surface features remain intact with some green paint remaining. The hatch and some of the surrounding concrete are missing, as are the louvres on the adjacent ventilation shaft. The top of the main ventilation shaft is missing and is to be found at the bottom of the ladder. A dome and aerial bracket on the ventilation shaft indicates this was a master post. Internally the post is a mess and fire damaged with 6" of water on the floor. There is a lot of rubbish. The only original items remaining are the folding table and shelf and the fuse box with some wiring.
