Aga Khan Award for Architecture: Wadi Hanifa Wetlands

Years of laissez-faire development led to damaging floods, mounds of construction waste and polluted water in the basin which serves a burgeoning population that grows increasingly dependent the source. The plan, a joint venture between Moriyama & Teshima Planners Limited  and Buro Happold was to turn the basin into a thriving natural reserve that not only would restore wildlife, but serve to provide benefits for the community. Water quality  was paramount in the restoration for both the water upstream and for the city’s wastewater which is intended to be stored and reused. To accomplish this 1.25 million cubic meters of construction debris were removed, and the haphazard roads and power lines were reorganized to reduce surface impact. Side water inlets have been reclaimed or added to aid in flood control and habitation.
Situated adjacent to the city, the basin is a major local and tourist attraction thus recreational facilities were combined with habitat enhancement and water quality  infrastructure. Natural stone weirs were installed to create a habitat for micro-organisms as well as to increase oxygen levels to reduce chloroform bacteria . The large bio-remediation facility is a one of a kind design which recreates a complex habitat, in turn treating the city and river water naturally. Downstream large Periphyton Benthic Substrate Devices (APBS) have been installed, which have given way to an underwater habitat.
The complex is also a large park which provides area to explore and interact with the water environment. Moreover, Wadi Bed Naturalized Parkland and Recreational and Interpretative Trail are also great examples of how answers to the challenges of water quality management and public access  can be woven together.
The parks use will only increase over time and anticipated to provide one million cubic meters of water per day by 2021 to meet a third of the city’s total water demand.
