The Water Treatment Plant dive site is located just off a water desalination plant built on the southern end of the Sunabe shore, hence it's name. The main attractions here are two man-made structures, which are overgrown with coral and swarming with schools of fish - the birdcage and the mushroom (a.k.a. the UFO). These are the water intake and outtake for the plant. A large school of barracuda can often times be seen close to the mushroom and attentive divers can easily spot many interesting nudibranchs.
