The facilities purpose was to store the bi product which is generated during the extraction of Nickel and Cobalt from the limonite ore at the Nickel Processing Facility located in Goro. The KWRSF consisted of the construction of a downstream dam and preparation of internal batters to receive placement of a LLDP liner in order to prevent seepage and protect the integrity of the dam. The KWRSF site is in a karst region which received on average 3.4m of rainfall per annum therefore extensive under drainage installation was required along with the construction of a concrete spillway which was used to manage runoff from the facility once it reached its storage capacity.
