Cat-793 fast-discharge Water Tank for BHPBilliton Pampa Norte (Cerro Colorado)
The attached hybrid water tank and dump body was recently completed at the Iquique workshop of Conymet Duratray. Initially designed as a high-volume water tank for pit dewatering operations, the unit can later be converted to a standard rock body for transport of ore and waste. A full 140,000 litre (40,000 US gallon) water tank can be discharged in less than 90-seconds.
