The Water Tower conservation project at the Public Abbatoir in Marsa took advantage of UHDC materials when it was reopened earlier this year. Built in the late 19th century, the landmark water tower was one of the first concrete structures in Malta, but had been slated for demolition because of its run-down condition. Researchers at the University of Malta were able to head that off by using the new advanced concrete, which is much stronger than average. With 12 columns and a religious statue underneath, the water tower is the height of a five story building and has been saved for use.
