Construction management of Kingsmill tunnel acid water treatment plant.

The Kingsmill tunnel was built in 1934 to drain tailings from mining operations in Morococha and it has two objectives: Yauli river decontamination and viability of the Toromocho mining project.

The HDS (High Density Sludge) process was selected for the water treatment because it represents the best conventional technology available to produce a high quality effluent and minimum volumes of chemically stable sludge at the lowest possible cost.

The plant is at 4,200 masl on the river bank, opposite to the tunnel intake. It has a 68m diameter clarifier, feed tanks and reactors, lime silo and a whitewash tank, located next to a building that will house a lime system, the replacement system of the flocculants polymer dry storage, compressors and blowers, maintenance area and spare parts, electrical control room and the laboratory area, offices and services.
