Abu Dhabi-based property development firm Aldar Properties has launched a water park on Yas Island. The 16.4 hectares water park will feature over 40 rides and attractions including four that have never been seen before in a water park, according to the developer. The project and construction work will begin in July 2010 and is planned to be completed in 2012. UK firm Atkins has been appointed as lead designer for the project.
