Sector 10 Wastewater Treatment Plant, Yarinacocha, Ucayali, Peru

Sector 10 is a wastewater treatment plant located in the Tushmo area of Yarinacocha, within the Coronel Portillo province of Ucayali, Peru. It serves the Pucallpa metropolitan area, a growing urban center in the Peruvian Amazon. The plant provides secondary treatment, a standard level for municipal wastewater in the region. As a secondary treatment facility, Sector 10 reduces organic matter and suspended solids before discharge. In Peru, wastewater treatment plants are regulated under national environmental standards (Ley General del Ambiente) and sector-specific norms. For plants serving urban agglomerations like Pucallpa, secondary treatment is typical to meet water quality objectives for receiving water bodies. The plant's treated effluent flows into local waterways that drain into the Ucayali River, a major tributary of the Amazon River. This region is ecologically sensitive, supporting diverse aquatic life and providing critical habitat for fish and other species. Proper treatment helps protect downstream water quality and the integrity of the Amazon floodplain ecosystem.

The plant discharges into the Ucayali River basin, which flows into the Amazon River and ultimately the Atlantic Ocean. This watershed is part of the largest tropical rainforest on Earth, supporting exceptional biodiversity. The treated effluent contributes to maintaining water quality in a region where aquatic ecosystems are vital for local communities and wildlife, including migratory fish species.
