Dewatering – Pipelines & Construction – Engineering

King Island Scheelite Limited – King Island, Tasmania

Dewatering Dolphin Tungsten Mine

The King Island project is on the south-east coast of King Island, the most western large island in the Bass Strait. Closed for 24 years, King Island’s Dolphin Tungsten Mine reopened in 2014 with some 3m3 litres in the Pit to dewater.

That’s where we came in! Our solution involved pontoon mounted diesel pumps, running 24 hours for 120 days and 720 metres of over the pit wall pipelines.

Water was pumped out of the pit at 400 litres per second and transferred 1.2kms to a discharge point on the ocean front.

Comprehensive training of onsite personnel was conducted on maintenance requirements and operation of the system once fully commissioned. Stage 1 was completed in October 2014 and work is ongoing.
