Implementation of Sustainable Sewage Systems in 06 municipalities in Western Paraná

ITAIPU Binacional (
Intergovernmental organization

    The Ocoí river basin is one of the largest and most representative contribution basins to the Itaipu Reservoir. This basin has shown increasing degradation of water quality, with the occurrence of hypereutrophic areas (high increase in nutrient pollution - nitrogen and phosphorus) due to the lack of a systemic environmental sanitation strategy. Few municipalities in the basin have investments in urban sanitation, which is one of the major gaps in sanitation and degradation of water quality in the Itaipu Reservoir. Environmental sanitation is one of ITAIPU's actions towards water security, approved by the Binational Environmental Management Master Plan, and has strategic relevance for the company, as it acts in reducing the high nutrient loads in the rivers of the water contribution basin, avoiding the eutrophication of the Itaipu Reservoir and future problems of biological invasion by aquatic macrophytes, outcrops of microalgae with toxic potential, and exotic species that cause degradation of the dam concrete, and the clogging of refrigeration systems of the plant. In this partnership, SANEPAR and ITAIPU will cooperate both technically and financially for collective implementation, in hydrographic basins, of sustainable sewage treatment systems and technological innovations in 6 municipalities in western Paraná. This partnership is aligned with the regulatory framework for sanitation implemented by the Federal Government and provides for the monitoring and measurement of environmental and socioeconomic benefits provided by the implementation of the Sewage Systems, to be measured by the body of experts of the Itaipu Technological Park Foundation (FPTI).

    Expected Impact

    With the investments, three municipalities in the region (Ramilândia, Serranópolis, and Missal), which have no sewage treatment systems installed, will be able to serve 100% of the urban population. Three other municipalities that already have some treatment system (Santa Helena, Medianeira, and Itaipulândia) will receive investments and innovative systems to improve sewage treatment processes, serving the population and reducing the intake of polluting nutrients by the Itaipu reservoir. Improvement of the rate of sewage collection and treatment service: Municipality of Missal: from 0% to 100% Municipality of Itaipulândia: from 69% to 70% ( in addition to tertiary treatment) Municipality of Ramilândia: from 0% to 100% Municipality of Serranópolis do Iguaçu: from 0% to 100% Municipality of Santa Helena: with 86% (in addition to tertiary treatment) Municipality of Medianeira: from 35% to 65%


    For this project, ITAIPU Binacional counts on the collaboration of the Sanitation Company of the State of Paraná (SANEPAR) and the Itaipu Technological Park (FPTI), in addition to the municipalities of Santa Helena, Ramilândia, Missal, Itaipulândia, Medianeira, and Serranópolis do Iguaçu.
