TCTA implements projects, from the development of economically sustainable funding models; to the design and implementation of environmental management and socio-economic strategies; through to the design of cost- effective and environmentally-sound infrastructure. In the past year, the Trans-Caledon Tunnel Authority has performed remarkably well - reaching significant milestones with two of its flagship projects, the Berg Water Project (BWP) and the Vaal River Eastern Subsystem Augmentation Project (VRESAP).
