Águas do Ribatejo Rehabilitation Tenders for Three Wastewater Treatment Plants (€6 million)

Águas do Ribatejo, an intermunicipal company that runs water supply and sanitation for about 140,000 inhabitants in seven municipalities of the Lezíria do Tejo region in Portugal, has launched public tenders to rehabilitate three wastewater treatment plants (ETAR). The plants are in Benfica do Ribatejo (municipality of Almeirim), Muge (municipality of Salvaterra de Magos) and Glória do Ribatejo. According to the source, these are separate tenders. The plants have operated for several decades. The buyer says they need deep works to meet current and future wastewater treatment requirements, including those of the new European Urban Wastewater Treatment Directive.

The scope differs by plant. At Benfica do Ribatejo, the rehabilitation will in practice amount to an almost entirely new installation, able to handle the higher flows from the expanded local sewer network. At Muge, new treatment processes are needed, in particular for effluent disinfection, because the plant discharges into the Tagus River near hydrologically sensitive zones. At Glória do Ribatejo, the ageing infrastructure must be adapted to stricter environmental standards.

The total investment for the three projects is around EUR 6 million. The buyer has applied for EU co-funding under the Sustentável 2030 (Sustainable 2030) programme. Works are expected to last between about one and a half years and just over two years, depending on the complexity of each intervention. The source does not give the value per plant, the procedure type, the submission deadline, the Q&A deadline, the start date, the submission portal or the bid language.
