Musanada, Al Ain Municipality begin $32.5m rainwater project
The project aims to reduce the risk of flash flooding in the 79.4km-long Al Ain, Al Sulaimi, and Al Tawayya valleys
The Abu Dhabi General Services Company (Musanada) and the Al Ain Region Municipality (ARM) have begun work on Package 1 of the $32.5m (AED119.3m) Al Ain Rainwater Streams project, which is aimed at reducing the risk of flash flooding in the 79.4km-long Al Ain, Al Sulaimi, and Al Tawayya valleys in the city of Al Ain.
The Al Ain Rainwater Streams project will contain rainwater and streams, thus reducing the potential risk of flash floods, while simultaneously continuing urban development.
The initiative’s scope of work includes cleaning and levelling the floors of three valleys, and restoring them to their normal shape to provide a regular stream of water without disruption or sharp runoff.
In addition, maintenance work will be carried out for rock and concrete protection barriers; repairing damaged ends of bridges, dams, and low waterways; as well as protecting and relocating infrastructure services.
The ARM has studied the risks of floods and runoff in Al Ain city through the torrents water discharge project in Al-Ain city.
The municipality now aims to assess the infrastructure conditions and capacity; identify the number of flash floods; and develop a master plan to study the risks of flooding in the Al Ain, Al Sulaimi, and Al Tawayya valleys in Al Ain city, as well as other priority areas that require protection from flood risks.
The ARM initiated the project across three main phases. The first phase involved the collection of information, data, and statistics related to rain, valleys, and dams. It also included the development of topographic surveys that involves studying the average precipitation and location of valleys and dams.
The second phase involved creating a geographic database and a hydraulic model to study the movement of rainwater.
The third phase comprised engineering solutions, including studies to analyse and select the best developed solutions for the protection of private and public properties. It also included planning the protection of lands in areas far from the risks of flash floods and runoff, as well as developing maintenance programmes for existing and future dams and valleys.
