Abu Dhabi-based Aldar Properties is to open a 16.4-hectare waterpark on Yas Island, the company's major leisure and entertainment destination.

Set to open in 2012, the park will feature more than 40 rides and attractions including four one-of-a-kind rides that Aldar said have never been seen before in a water park.

The property giant has already received the conceptual planning approval from the Abu Dhabi Urban Planning Council and has appointed the UK-based Atkins as lead designer for the project.

The prequalification process for main contractors for the project has now been launched and construction work is scheduled to begin in July 2010.

Aldar has also committed to making the attraction one of the most environmentally friendly and sustainable water parks in the world.

Sami Asad, chief operating officer, said: "The water park will bring in another distinct feature to Yas Island, further diversifying its already impressive offering.

"It will be a valuable addition to the other attractions that will set Yas Island apart as a major leisure destination and will reinforce Abu Dhabi's position as a great place to live, work and visit."

The park will be one of a wide range of leisure projects at Yas Island, including the Ferrari World Abu Dhabi, the Yas Marina Circuit and seven hotels.
