Name of the Project
Jangwani Flood Protection Project
Jangwani Bridge forms a link between the city center and the north-wester part of the city.
The Msimbazi River Basin has a catchment area of about 270 km2, and the Jangwani area is located around 2,5 km before the outfall of the river into the Indian Ocean. Jangwani Bridge forms a link between the city center and the north-wester part of the city via Morogoro Road, crossing the river. It facilitates the Bus Rapid Transport (BRT) public transport system. Next to the Jangwani Bridge, the BRT Depot is located in the Jangwani valley. During high flood events, Morogoro Road and Jangwani Bridge get flooded, making the crossing of the valley impossible.
The traffic comes to a stillstand. The BRT depot is not designed to withstand flooding impacts of recent flooding events. Water and sediments enter the depot, damaging not only the depot’s structures and obstructing the drainage system, but also the parked busses inside. In the year 2018, the rainfall caused flooding events with the said impact 4 times and this has been increasing since the year 2011. The main objectives of the here described Consultancy Services are to: i) address the flooding at Jangwani Valley, ii) ensure uninterrupted traffic flow on the Jangwani Bridge while at the same time and iii) safeguard the Bus Rapid Transit (BRT) depot infrastructure.
