T he faster construction time and higher quality finish are the principal reasons that the City of Ekurhuleni’s Department of Water and Sanitation once again opted to build a reservoir in its jurisdiction using precast concrete technology. Notably, this is the fourth large reservoir to be constructed in Ekurhuleni in this manner. The four reservoirs will help the municipality augment water supply, with this reservoir catering specifically to the anticipated doubling in water demand due to several planned new large develop- ments in Pam Brink and Dal Fouche, a neighbouring suburb. Work on these de- velopments will commence shortly after the finalisation of the construction of the reservoir and related infrastructure. The system was approved by Tango’s Consultants, which was appointed as the design engineer for the construction of Tian de Jager Director Corestruc Kobus Kotze Director Infinite Consulting Engineers Willie de Jager Managing director Corestruc Kadiebwe Jean Paul Mulunda Civil Engineer Technologist Tango’s Consultants Unique precast concrete reservoir for City of Ekurhuleni A unique approach has been deployed to construct a new 25 Mℓ reservoir in Pam Brink, a suburb of Springs, Gauteng. With construction now nearing completion, this local innovation has again proved to be a quicker means of building large reservoirs while also providing a higher quality final structure than is possible using traditional construction methods.
