It took two pallets to transport and was used to build a 500 cubic metre reservoir in Africa by Pureco Kft.

A water storage tank with special properties has been installed in Ghana by Pureco Kft. The Hungarian company, which operates in countries on four continents, managed to install the product in five days under extreme weather conditions and without the use of mechanical power.

The company, which provides sustainable water management solutions, says it has installed an above-ground tank, one of its latest water storage products, which does not require significant excavation work to install.

"The reservoir equipment adapted to local needs is a novelty because until now we have only offered underground and above ground tanks, this is the first type of tank that is both above ground and stationary"

- they pointed out. They added that the product is commonly used in agriculture, horticulture, aquaculture and industry.

With everything on two pallets, a 500 cubic metre reservoir was built

Pureco first used the stationary tank in Africa, where it was installed in the wastewater treatment plant in Takoradi, Ghana, also built by the Hungarian company. The report showed that the wastewater treatment plant requires a significant amount of process water, which had previously been supplied from wells dug in the area to a depth of 100 metres. However, the project has shown that much more water is needed than can be provided by pumping water from the wells once. They therefore switched to continuous well water abstraction, for which the construction of a reservoir system was essential. Given the terrain and soil quality of the area, and the short timeframe, the investors opted for a permanent product.

One of the significance of this ground-breaking project was that the Pureco was able to experience all the benefits of the product during delivery and implementation.

"The tank, which has a capacity of 500 cubic metres, or 500 000 litres of water, is 12 metres in diameter and 4.6 metres high, and can hold all its accessories on two pallets" - because it is delivered in 2.4 metre-long segments, the summary says. "This made the accommodation much easier. We were able to complete the installation in five days, even without any motorized mechanical power (hoists, cranes, etc.) on site."

100% waterproof and extremely durable

Moving on to the product parameters, they said the panels of the Pureco upright tank are 0.8-2.5 mm thick depending on the height of the tanks, Takoradi's tank is made of 0.8-1.25 mm thick S350 grade steel with a 450 g/m² galvanized coating on both sides.

The steel structure itself is not watertight, so the tank is lined with an internal foil liner, which can be 0.6 or 1 mm thick. In Takoradi, the tank is also lined with a special foil layer, which ensures 100 per cent water tightness. The tank also has a reinforced PVC foil lid. The base material is a polyester fabric coated on both sides with PVC: the 850 g/m² material is extremely durable.

Reassembled on another site

In conclusion, the benefits of the product were listed in detail:

• easy transportability and installation, as the 500 cubic metre tank took up no more than two pallets;
• rapid deployment, as the product could be installed in Africa in five days in extreme weather conditions and without mechanical power;
• can be installed without major excavation work, as it is above the ground and only requires a concrete base, or even on paving slabs;
• a mobile system that can be adapted to the needs of each case, as an assembled tank can be dismantled after emptying and even reassembled at another site.

The advantages of the technology are illustrated by the fact that if this 500 cubic metre tank had to be built using conventional concrete technology and installation, the investment cost would have been more than ten times higher and the installation time at least four times longer.
