The Qatar Public Works Authority has awarded two contracts for the design and construction of sewage tunnels to Bouygues Travaux Publics (a subsidiary of Bouygues Construction), in partnership with a local contractor, UrbaCon Trading & Contracting.

The two contracts are worth approximately €550 million, of which Bouygues Travaux Publics’ share amounts to roughly €285 million.

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.

The 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, necessitating the redesign and expansion of its sewage system.

The Qatar Public Works Authority is now putting 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.
