Brown & Root reports it has carried out engineering and construction supervision to convert two limestone caverns 50-150 m-deep for potable water storage. The two main caverns are 120 m-long x 40 m-wide, with three interconnecting tunnels and two access adits. A new low level outlet tunnel was constructed and one access adit was converted to a hydraulic inlet. Visit www.halliburton.com July 2000.
