Value for money = no loss of water + no waste of time fixing tank problems…
Time, money and water are a farmer’s three most precious assets. An issue that has been of growing concern to many large polyethylene water tank owners in both domestic and commercial situations, is the problem of collapsing tops and splitting sidewalls.
A band-aid remedy for collapsed rooves has been to insert one or more PVC pipes inside the tank. These have had limited success because during high winds, the rooves of the tank can lift, causing the poles to fall over. However, this can be a difficult task to fix once the roof has sagged. Firstly, half the volume of water must be dumped. Then, with considerable effort, the roof must be pushed up and the pole re-inserted. A further problem can occur when the pole/s wear a hole through the roof, allowing vermin to access the tank.
During the last 5 years, reports of splitting and bursting tanks have been on the increase. If you consider that most tanks come with some sort of warranty or guarantee, this should not pose a problem. However, the real issue is not whether the tank is replaced.
The problem lies in the risk of damage and/or injury that can be caused by 25-40 tonnes of water, chemicals or molasses escaping at a very rapid rate. It has been reported on many occasions that buildings have been undermined, and other costly losses have been incurred, without compensation.
With fierce competition now prevalent in the industry, prices have been forced downward. This trend has sadly had a detrimental effect on the quality of the products available. This has resulted in cuts in the amount of poly used to make the tanks, thereby producing thinner tanks. The thinness of the tank wall, combined with poor design, is often the cause of the above-mentioned tank problems.
The actual design of the tank plays a very important role in the performance and lifespan of the tank. It has recently become obvious that many of the current designs have major shortcomings.
Polyworld has put in thousands of man-hours of research and development, followed by meticulous tank engineering and design. The result is a range of tanks with a unique appearance, and an incredible amount of strength and durability.
The product range includes under-eaves domestic water tanks, transporters, chemical tanks and troughs in an array of shapes and sizes. Polyworld’s signature design can be recognized by the large block-type ribs on the top, which have been designed like a bridge. This is one aspect that gives the tank its incredible strength.
Proof of this strength is that two people can walk across the main beam without the use of support poles (a world-first for this size tank). As another strength test, the tank was tipped upside down. The roof easily supported the total weight of the tank without collapsing.
The other major difference is the rib design on the sidewall. A series of horizontal rolled, filled ribs, each 200mm apart, with a thickness of 15mm, has given these tanks a greatly increased overall strength, eliminating the risk of bulging or splitting.
