TUNISIA: call for tenders to renovate Korba and Haouria wastewater treatment plants

Tunisia's National Sanitation Office (ONAS) is launching a call for tenders to renovate the Korba and El Haouria wastewater treatment plants in the governorate of Nabeul, in the north-east of the country. Interested companies have until 19 December 2023 to apply.

In Tunisia, the National Sanitation Office (ONAS) wants to improve the efficiency of wastewater treatment plants, particularly those at Korba and El Haouria, in the governorate of Nabeul. The public body has just launched a call for tenders to recruit the company responsible for rehabilitating these plants. Interested companies have until 19 December 2023 to apply.

This project is being implemented as part of phase I of the sanitation programme for small towns with fewer than 10,000 inhabitants (PAPC-I), which will make it possible to continue connecting 33 municipalities in 19 governorates to the sanitation network, and to improve the living conditions of residents and the health of their natural environment. This will be achieved by rehabilitating and building sewerage infrastructure (primary and secondary networks, transfer networks, pumping stations and treatment plants), building human capacity and providing institutional support.

At the Korba plant, for example, the company selected following the call for expressions of interest launched by ONAS will be refurbishing the electronic pre-treatment equipment. Its terms of reference also include civil engineering maintenance and repair of the works dedicated to the pre-treatment of the wastewater treatment plant.

The work will be more extensive at the El Haouaria treatment plant. These include the construction and equipping of a pre-treatment unit, the construction and equipping of a new pumping station for treated wastewater, the supply and laying of 4,900 m of pipes for treated wastewater, with a diameter of 500 mm, and 300 m of pipes for transporting treated effluent, with the same diameter. The sewerage programme is being financed by Onas with the support of the African Development Bank (AfDB) and the European Bank for Reconstruction and Development (EBRD).
