Overview
ETE CATOLE DO ROCHA is a municipal wastewater treatment plant serving Catolé do Rocha, Paraíba, Brazil. It treats wastewater from approximately 10,965 residents in the semi-arid Northeast region.
ETE CATOLE DO ROCHA is a municipal wastewater treatment plant located in the Tapera district of Catolé do Rocha, in the state of Paraíba, Brazil. The plant serves a population of approximately 10,965 people, placing it in the small-to-medium agglomeration category for the region. As a Brazilian wastewater facility, the plant operates under the national regulatory framework established by the Ministry of Cities and state environmental agencies such as SUDEMA (Superintendência de Administração do Meio Ambiente da Paraíba). The plant discharges treated effluent into local watercourses that drain into the Piranhas River basin, which flows eastward to the Atlantic Ocean. The semi-arid climate of the region makes water quality management particularly important for maintaining aquatic ecosystems and supporting downstream communities.
Environmental context
The plant's treated effluent enters the Piranhas River basin, a major drainage system in northeastern Brazil that flows through Paraíba and Rio Grande do Norte before reaching the Atlantic Ocean near Macau. The region's semi-arid climate means rivers have variable flows, making consistent wastewater treatment critical for protecting aquatic life and preventing eutrophication in downstream reservoirs and coastal waters.
