WHY CHOOSE WEST COAST POLY

West Coast Poly has earned an impressive reputation as one of the leading and largest manufacturers of polyethylene storage tanks in Western Australia.
KEY FEATURES
The superior strength of a West Coast Poly tank is attributable to the additional materials used in its construction and the reinforced lower wall. Water pressure increases with depth, hence the stress increases towards the bottom of the tank, concentrating material in this area ensures a stronger more durable product.
West Coast Poly water tanks are engineered with a unique rib profile, designed specifically to maximise the strength of your tank. This unique rib profile increases wall stiffness without creating thin spots normally associated with ribbing.
West Coast Poly water tanks are of one piece construction with the roof integrated into the body of the tank rather than attached by screws or rivets. This makes the overall tank stronger and eliminates the possibility of the lid coming off in high winds or cyclonic conditions.
All West Coast Poly water tanks have an integrated leaf strainer, or screwed access hatch to prevent insects and other pests entering the tank, even the overflow has a mosquito proof screen. This means clean hygienic storage for your precious water supply.
West Coast Poly water tanks are manufactured from resins approved under AS4020:2018 the Australian Standard for potable (drinking) water and for food contact under the Australian Standard AS2070. These standards are your guarantee of a taint free water supply.
Resistant to a wide range of chemical environments, these tanks will never rust or corrode even with high salt or iron content waters. They can be installed on any smooth level surface.
West Coast Poly tanks use state of the art ultraviolet stability UV 20 System, effectively doubling the UV resistance formulated to handle the extreme conditions of Australia and New Zealand. This means additional peace of mind with regard to weathering.
West Coast Poly is a Western Australian company located in Canning Vale, giving you easy access to the manufacturer for special fittings or installations and ensuring your money stays in W.A. A tank made in Western Australia for Western Australian conditions.
Rest Easy. The purchase of a West Coast Poly rural/agricultural water tank brings with it a written 20 year guarantee*. Backed by the manufacturer, you can be assured only the best workmanship and best materials have gone into your new tank.

INSTALLATION AND MAINTENANCE
The following information is a guide to installing tanks from 4,500 Litre (1,000g) to 50,000 Litre (11,100g)

CRITICAL POINTS TO REMEMBER
- If a sandbase is used we advise that intermittent checks over a period of time should be made for the effects of erosion.
- Base of tank must be fully supported across its entire area (base support must remain flat at all times).
- Failure of the tank due to insufficient base support is not the responsibility of the manufacturer.
- Pipe work should not place any loading on tank wall (flexible coupling is recommended).
- Overflow size must be equal or exceed inlet size.
- Tank must be vented to prevent it being subject to pressure or vacuum (leafstrainer or breather must be installed).
Please note it is the responsibility of the purchaser to ensure the tank base is Compliant with supporting the storage tank and ongoing maintenance. Failure to do so will void the warranty.
