The Public Works Authority 'Ashghal' announces the completion of construction works of the rainwater and groundwater network in Al Thumama area (Zone 46) with a total length of 26 km covering 50 streets. This newly constructed network is part of the stormwater and ground water infrastructure development project in areas South of Doha, which aims to reduce rainwater accumulation and control the groundwater level in the area.
On this occasion, Eng. Khalid Al Khayareen, Drainage Network Projects Department Manager, stressed the importance of the development works that are implemented, as Al Thumama area is one of the vital areas in the country that is witnessing great urban and population growth. The location of the works increases the project’s importance as they are implemented near Al Thumama Stadium, one of the eight stadiums hosting the FIFA World Cup Qatar 2022.
Eng. Khalid Al-Khayareen explained that the new network would accommodate rainwater flows from Al Thumama (Zone 46) to Abu Hamour Tunnel through Al Najma Tunnel and transfer it to the main drainage network. This will contribute to reducing rainwater accumulation, meeting the needs of the population and improving the quality of life and environmental conditions in the area.
On the scope of works, Eng. Hassan Mohsen, Head of the Drainage Networks Projects Section at Ashghal, stated that a total of 26 km of surface and groundwater drainage network pipes have been installed, at a depth ranging between 5 and 26 metres below the ground surface. This is divided into 9 km of rainwater drainage network lines, which are implemented using deep micro-tunneling technique to mitigate the effects of excavation works on the traffic and residents of the area. In addition to about 17 km of shallow rainwater drainage network lines, of which 5 km are perforated lines that will also serve to control the level of groundwater.
Eng. Hassan Mohsen added that about 97% of the construction works of the rainwater and groundwater drainage network in Al Thumama (Area 46) have been completed and the final works are currently being completed to inspect the network and implement road reinstatement works. He explained that the new network covers 50 streets, most notably the E-Ring Road, Najma Street, Al Thumama Street, Al Quds Street, Al Madinah Street and Masjed Al Haram Street. The network also serves Kahramaa Awareness Park and Al Furjan markets in the area.
Works also included the construction of 50 manholes and 200 gullies, in addition to connecting more than 1,500 existing gullies to the new network to enhance its efficiency.
