The demand for versatile efficient, ecofriendly water-storage containers in SA is growing daily as a result of population growth, as well as mining, industrial, agricultural and property development projects that are forging ahead like never before. Bruce Thompson, the agent for the Australian-based company Heritage Tanks, says this demand is being met by this international company’s pioneering expertise in the field of water storage systems’ design and manufacture.
Heritage tanks has been supplying its modularised reservoirs to the market for a number of years, but following its recent 2008 Nampo Harvest Day exhibition, these reservoirs have really gained popularity. The reservoirs are currently imported by the container load and are available throughout south and central Africa. The tanks are versatile and can be used for a variety of purposes ranging from rainwater storage, domestic-water storage, water purification and aquaculture, in addition to the storage of fluids such as oils and molasses.
Tailor-made sizes
Tank capacities range from 52 000â„“ to 500 000â„“ in the standard range and much larger in the specialised range. outer-steel walls of the tanks are generally 1mm thick and come either in corrosion-resistant standard Zincalume panels or in a range of equally tough, colourbonded panels to suit the preferences of customers. he liners are made by Jaylon Industries, one of the largest liner manufacturers in Australia, from 0,75mm polyethylene co-vinyl acetate (EVA) of international food-grade quality. The liners, although welded together, come made-to-size for the specific tank ordered by the customer.
Minimum tensile properties:
Membrane density 0,942g/cm
• Tensile strength at break 25 N/mm2
• E longation at break percentage: 700%
• Puncture resistance: 255N
• Tear resistance: 67N
Features and cost
Heritage tanks have low, dome-shaped roofs that add strength and stability through sturdy, engineer-designed trusses and corrugated steel sheets. The roof seals out windblown debris, algae and creatures such as birds and rodents
Easy to set up
The tank package, which is easily transportable and can be assembled on site by the farmer, includes a number of quality accessories as well as all the components necessary for assembly. The tank walls are bolted together on site. he outlets and overflow-tank fittings are made from brass. Ball valves, fire-fighting fittings and overflow pipes are attached, as well as a 150mm deep mesh, leaf catching assembly. A lockable manhole cover is made from Zincalume. Prices range according to size from the smallest at R37 520 to the largest at R108 800. These prices are expected to increase as a result of international steel-price increases. – Annelie Coleman For more information contact Auriel Mitchley on (011) 889 0796 or e-mail [email protected].
