Dewan Architects designs the largest water theme park in Qiddiya, KSA


Dewan is the lead design consultant for the Qiddiya Water Theme Park in KSA, which is estimated to be the biggest water park in the world.

The newly announced Qiddiya Water Theme Park is one of the flagship projects of Qiddiya, one of the most happening destinations in KSA at the moment. The destination is considered to be the capital of entertainment, sports and the arts in the Kingdom of Saudi Arabia.

Dewan is the lead design consultant for the Qiddiya Water Theme Park. The architectural firm has successfully delivered the design and is now supervising the physical construction of the development. The collaborative project includes the architects working with a team of renowned water theme park experts, ride vendors, and engineering and infrastructure professionals.

Earlier this year it was announced that ALEC Saudi Arabia Engineering and Contracting and El Seif Engineering Contracting were the contractors and build partners for the project.


The water theme park is estimated to be the biggest in the world.

His Royal Highness Mohammed bin Salman, Crown Prince, Deputy Prime Minister and Chairman of the Council of Economic and Development Affairs and the Qiddiya Board of Directors, as part of Vision 2030, announced a blueprint for the long-term prosperity for the the site, part of which is economic diversification and increasing the household spending on domestic leisure and entertainment.

The water park will be at the heart of the attractions at Qiddiya, close to the country’s capital, Riyadh. The expansive project will cover 337,948 square metres of land and include 22 rides, nine of which are expected to be world-firsts. The Qiddiya Water Theme Park will have nine distinct districts inspired by native animals and habitats, including Camel Rock, the Den, the Herding Grounds and Arabian Peak.

The overall project is expected to be 137,948 square metres, which when completed will be considered the largest water park in the world.

The water park is part of the overall giga-project and is budgeted to cost $750 million. Dewan Architects announced that it will use smart technologies to ensure that its operation aligns with its sustainability efforts. The architects are at the moment using environmental systems that will allow them to use 75 per cent less water than traditional practices. They have also looked into using technologies to help reduce evaporation concerns and the subsequent wastage.

Additionally, the design of the park is said to allow for state-of-the-art facilities to host world water tournaments.

The allure of Qiddiya

Qiddiya is surrounded by nature in the heart of the Tuwaiq Escarpment Environmental Reserve. As such, Dewan is working closely with the Qiddiya Investment Company to ensure that the project is in accordance with the overall plan for the place. The design is planned around various ecosystems and therefore the architects announced that they are working with the local authorities to ensure that the environment and its natural inhabitants are protected.
