en.Wedoany.com Reported - On June 16, the Brazilian Serra da Mantiqueira Consortium (Consórcio Serra da Mantiqueira) won the auction for the water supply and sewage treatment service concession in the municipality of Andradas, Minas Gerais. The consortium, composed of Infrainvest Participações, Águas de Valência do Brasil, and Senha Engenharia e Urbanismo, submitted a winning bid of R$44 million in concession fees, representing a 130.35% premium over the minimum concession fee of R$19.1 million.

Other bidders included the Andradas Saneamento Consortium (Consórcio Andradas Saneamento, composed of Sanea Ambiental and IFX2 Concessões), Terracom Concessões e Participações Ltda, and the Águas de Andradas – Minas Gerais Consortium (Consórcio Águas de Andradas – Minas Gerais, composed of Cimcop S.A. Engenharia e Construções, Torc Terraplanagem, and Planex S.A. Consultoria de Planejamento). The bidding proceeded to an on-site competitive round, where parties submitted final offers. The second-highest bid was made by the Andradas Saneamento Consortium, amounting to R$43.6 million (a 128.25% premium), close to the winning bid.
The sanitation project plan anticipates investments of R$209.3 million over the 30-year contract period, with R$139.8 million required within the first eight years of the concession. Services covered by the contract include water abstraction, treatment, and distribution; sewage collection and treatment; as well as network expansion, system maintenance, implementation of operational efficiency mechanisms, and public-facing services.
The contract sets specific targets, including increasing water supply coverage in urban areas and districts from 96% to 99%, raising the sewage treatment rate from the current 10% to at least 90% (sewage collection rate has already reached 94%), and reducing water distribution losses to 25% by 2033. The concession also establishes a social water tariff (Tarifa Social), which, based on estimates from the Single Registry for Social Programs (CadÚnico), could benefit approximately 2,400 families, representing about 5.9% of the municipality's population.
