Water is a valuable commodity in Kuwait – bottled water is even more expensive than petrol. Consequently, the six water towers that were built in the Al Jahra area in Kuwait City are an investment of decisive importance for cities in that country.
The huge, mushroom-shaped water tanks have already become a landmark of the country and can be seen from afar thanks to their blue and white stripes. The elevated tanks are 38.5 m high and have diameters of 32 m at the upper rim of the water tanks. This way, the tanks can store more than 2.4 million litres or 650,000 gallons of fresh water.
The towers' mushroom-shaped water tanks were post-tensioned using DYWIDAG Strand Tendons. DSI supplied 66 6-0.5" DYWIDAG Ring Tendons with anchorages and accessories to post-tension each tank.
Initially, the ducts and tendons were installed into the formwork at ground level. They were then hydraulically lifted onto the pillars of the water towers. Afterwards, concreting, post-tensioning and grouting of the tendons were carried out using the equipment that had been supplied by DSI.
