Bouygues Travaux Publics (BTP) and Qatari construction firm UrbaCon Trading and Contracting have been awarded two contracts for the design and construction of sewage tunnels by the Qatar Public Works Authority.
The contracts are worth a total of $610m, of whichBTP’s share amounts to roughly $320m.
The team will construct two tunnels under Doha. The north section will be 16km long and 3m in diameter and the south section will be 14km long and 4.5m in diameter.
The contracts are part of a strategic project for sewage collection, pumping and treatment services in the south of Doha known as the Inner Doha Re-sewerage Implementation Strategy.
In recent years the Qatari capital has experienced sustained population growth, which has necessitated the redesign and expansion of its drains.
The Qatar Public Works Authority decided to put in place a modern sewer network made up of large networks of underground collection systems. Â
The system has been designed according to the principles of sustainable development, and makes use of gravity to ensure the flow of wastewater in the tunnels.
Work on the project began this summer and is scheduled to finish in 2019.
In April BTP won a $295m contract for Line 3 of the Cairo metro.
