Dowdens Pumping and Water Treatment supplied 13 underground skid-mounted dewatering pods and a mains road pump station (‘Fish Tanks’) for Ausenco’s Kestrel Coal Mine Expansion, located 50km northeast of Emerald, Queensland.

The Kestrel Coal Mine produces coking and thermal coal, and the expansion has extended the life of the mine by 20 years. Portable ‘Fish Tanks’ are used in underground mines as a part of the water management process.

The Problem

The Kestrel Coal Mine Expansion required Portable ‘Fish Tanks’ which are used for dewatering as part of the mine site’s water management process.

Our Solution

Dowdens Pumping and Water Treatment designed, manufactured and supplied relocatable (skid-mounted) ‘Fish tank’ pump stations.

Each ‘Fish tank’ pump station is comprised of a Hopper (a sump on a skid), a horizontal centrifugal pump coupled to an explosion-proof motor, and a hopper level control switches hardwired to an on-board, explosion-proof Motor Control Cubicle / Starter, and Flowmeter. All of these increase the efficiency of the product.
