Jean-Philippe Trin, Deputy CEO with responsibility for Bouygues Travaux Publics, DTP and VSL, said: “We are proud to have been chosen by the Qatar Public Works Authority. For this ambitious project, we have developed an innovative technical solution that will enable us to address the customer’s concerns effectively and fully meet their expectations.”

In partnership with the local contractor UrbaCon Trading & Contracting, Bouygues Travaux Publics will construct two sewage tunnels in Doha. The north section (MTS01) will be 16 kilometres long and 3 metres wide. The south section (MTS03) will be 14 kilometres long and 4.5 metres wide.

These contracts are part of the strategic project for sewage collection, pumping and treatment services in the south of Doha, known as “IDRIS” (Inner Doha Resewerage Implementation Strategy). In recent years the Qatari capital has experienced sustained population growth, which has necessitated the redesign and expansion of its sewage system.

On this basis, the Qatar Public Works Authority decided to put in place a modern sewer network made up of large networks of underground collection systems. The system has been designed according to the principles of sustainable development, making use of gravity to ensure the flow of wastewater in the tunnels.

The wide-reaching project began this summer, with handover scheduled for 2019.

Bouygues Construction has been present in Qatar for several years. Bouygues TP constructed liquid gas storage reservoirs in Ras Laffan in the north between 1993 and 1996, while Bouygues Bâtiment International is finishing off its first project in the emirate, the Qatar Petroleum District, a 700,000 m² property complex including nine office towers, a five-star hotel with 400 bedrooms, 5,300 parking spaces, a conference centre, etc.
