In 2006 the “Active, Beautiful, Clean Waters” Programme (ABC Waters) was introduced in Singapore. The purpose of the Programme was to transform the country’s water bodies beyond their functions of drainage and water supply into lakes with new spaces for recreation as well as increasing the level biodiversity.

The challenge faced in the Bishan-Ang Mo Kio Park project was to transform an existing 2.7 km straight Kallang concrete channel into a more dynamic and natural river system. The goal was to create a sustainable and eco-friendly park that not only accommodated the fluctuating water levels of the river but also provided a relaxing and lush environment for visitors. Additionally, the project aimed to contribute to Singapore’s commitment to enhancing and managing urban ecosystems, aligning with the Active, Beautiful, and Clean Waters Programme (ABC Waters).


The solution involved the implementation of blue-green infrastructure (BGI), which combines hydrological elements (blue infrastructure) like rivers and canals with vegetation systems (green infrastructure) such as trees and floodplains in urban landscape design. BGI was used to replace the traditional ‘grey’ infrastructure, such as the old Kallang channel, with a nature-based approach that could adapt to the dynamic processes of the river system. This approach not only provided an aesthetically pleasing environment but also offered ecosystem services, including sustainable water and stormwater management, and various benefits to the community.


The result of the Bishan-Ang Mo Kio Park project was the successful transformation of a conventional concrete channel into a vibrant, semi-natural winding river surrounded by a 62-hectare park. This introduction of the naturalised river into the park has increased the biodiversity of the park by 30%.

The park now features three playgrounds, restaurants, a vantage point constructed using recycled concrete, lush vegetation, ponds, gardens, river plains, and open green spaces. The implementation of blue-green infrastructure not only addressed the challenge of managing fluctuating water levels but also contributed to the overall sustainability of the urban ecosystem. The project aligned with Singapore’s commitment to the ABC Waters Programme, showcasing the successful collaboration between Ramboll Studio Dreiseitl and various municipal partners, including Singapore’s National Parks Board and Public Utility Board. The result is a green and resilient space that provides recreational opportunities, supports biodiversity, and offers ecosystem services for the well-being of the community.
