Tanks for Mining Sites

West Coast Poly produces quality polyethylene storage tanks of maximum strength and durability, suitable for a wide range of mining applications. Their versatility and resistance to weathering makes these tanks the ideal choice for potable water, process water and chemical storage in the harsh mining regions of Western Australia.

Our experienced staff will gladly assist with configuring tanks to your specific requirements. They can advise on a range of fittings and flanges, level gauges, sight tubes, access hatches, vortex breakers and a host of other related products to enhance the tanks performance in your particular application.

Based in Perth, we operate our own fleet of product-specific delivery vehicles meaning that we can deliver on relatively short lead times to Kalgoorlie, Leonora, Wiluna, Newman, Port Hedland and surrounding areas.


Points to Consider

Our aim at West Coast Poly is the selection of the most cost effective long-term solution to your storage requirements and without the right information we can't do our job properly. In industrial applications additional hazards can arise that would not normally be encountered with rainwater storage, the items listed below are for guidance only:

UV Resistance

West Coast Poly tanks are manufactured to cope with the harsh West Australian environment and are suitable for external installation. West Coast Poly uses material which has a UV performance level of UV 20 which is more than twice the Australian standard requirement of UV8. This material is standard for our storage tank range so that customers can be assured they are getting the highest UV protection available.


The properties of polyethylene are affected by temperature and special consideration needs to be given where the tank is to be subjected to liquid temperatures above 35 deg C or below minus 20 deg C. The external air temperature is generally not as important as the temperature of the liquid being stored, however your supplier should be made aware if the tank is to be subjected to temperatures other than ambient.

Pressure or Vacuum

Tanks are typically manufactured for hydrostatic loading only and should not be subjected to pressure or vacuum.

Specific Gravity (SG) of liquid

Our tanks are typically manufactured for liquids weighing no more than 1 kg per litre ( SG 1.0), if heavy liquids like dissolved fertilizers, brine solutions, etc are to be stored in the tank then you must advise us at the time of order so that greater wall thickness can be used.

Installation Environment

Tanks are generally designed for external installation at ground level in a non-hazardous environment. They must be fully supported across their entire base area, (refer installation section for details). If your tank is to be inside or close to a building, elevated above ground level, partially or totally buried, located in a traffic area or in any other situation, which increases the level of hazard, you should advise us so that an additional safety factor can be applied.

Additional Hazards

Areas of high wind, cyclone susceptibility or seismic activity are the most common additional hazards, however, flooding, soil subsidence, feral animals, caustic cleaning solutions and many other factors can play a part. You are the best judge of the hazards in your environment, so please inform us, “we can’t provide for something we don’t know about”.
