ETE MOINHOS Wastewater Treatment Plant, Lajeado, Rio Grande do Sul

ETE MOINHOS is a municipal wastewater treatment plant located in the Moinhos district of Lajeado, in the state of Rio Grande do Sul, Brazil. The plant serves a small population of 817 residents, reflecting its role in a localized community within the broader Lajeado urban area. The plant provides secondary treatment, which is the standard biological treatment level required for municipal wastewater in Brazil under national regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant reports a discharge volume of 95.04 cubic meters per day, indicating its scale relative to the population served. Treated effluent from ETE MOINHOS is discharged into the local watershed, which ultimately drains into the Taquari River basin and then into the Jacuí River, eventually reaching the Patos Lagoon and the Atlantic Ocean. The plant helps protect downstream water quality in this ecologically important region, which supports diverse aquatic life and is used for recreation and water supply.

The plant discharges into the Taquari River basin, a tributary of the Jacuí River, which flows into the Patos Lagoon, one of South America's largest coastal lagoons. The lagoon supports diverse aquatic ecosystems and is a critical habitat for migratory birds and fish species. Proper wastewater treatment is essential to prevent nutrient pollution and maintain water quality in this sensitive downstream environment.
