» BNDES assigns R$ 18m for sanitation and reforesting in Niterói
BNDES’ management signed off a R$ 18m loan for the utility company Águas de Niterói S.A. The funds will be used to expand the Toque-Toque Sewage Treatment Station, in the city of Niterói (Rio de Janeiro state). This project will allow processing of over 225 liters per second of sewage and, more importantly, the expansion of the sewage network of the Oceanic Region of the city and reforesting of water sourcing areas. BNDES’ money injection corresponds to 80% of total investments.
The project, part of the Growth-Acceleration Program (PAC) will implement 33 thousand meters of sanitary sewage collection network in the Oceanic Region of Niterói and reforesting of gallery forests in the water sourcing areas of Imunana System. This is the system responsible for the supply, with treated water, of around 1.5 million of people living in the cities of Cachoeira de Macacu, Niterói, São Gonçalo, Itaboraí and Ilha de Paquetá.
Itaipu Basin, composed of the districts of Itaipu, Itacoatiara and Engenho do Mato, in the Oceanic Region of Niterói, has a tertiary-level sewage treatment station, since January 2004, plus a 130 km collecting network, seven pumping stations and about 7,500 household connections.
The sewage-collecting network of over 33 thousand meters in this basin will complete the coverage of sanitary sewage in the districts of Itaipu and Engenho do Mato, bringing benefits to Itaipu Lagoon. The collecting network to be installed will be connected to the households not provided with the sewage system of Itaipu Basin, and will lead to the Sewage Treatment Station of Itaipu, in Campo Belo, in the city of Niterói.
The reforesting of the gallery forest along Macacu river, the main water sourcing of the system, is critical to prevent aggradation of rivers and keep the quality of waters. The public supply of water has been threatened during months of drought, due to decreased volume and low quality of gross water, requiring greater amounts of chemicals to reach the potability standards required by legislation and requiring longer treatment times, which reduces the production capacity and increases final costs.
Among the reforesting actions to be taken we can underscore the physical characterization of the field of performance, with the preparation of a georreferenced database. After defining the priority areas for the implementation of the project, the reforesting efforts will start. Two and a half million seedlings are expected to be planted. At the same time, activities involving marking of breeders, development of a seed garden and a forest yard will be performed. This will provide a production capacity of around 800,000 seedlings a year.
It is worth underlining that this region will host the new Petrochemical Complex of Rio de Janeiro – Comperj, with investments expected to reach R$ 5bi, which will require larger supply of water to address the forthcoming population growth of these cities.
Águas de Niterói S.A. is a private specific-purpose company (SPE) incorporated in October 1997, intended to provide basic sanitation services for the city of Niterói – RJ. The concession has been recently extended up to August 2042.
