Atoyac Sur Wastewater Treatment Plant, Puebla, Mexico

Atoyac Sur is a wastewater treatment plant located in Puebla, Mexico, serving a population of approximately 397,948. The plant is situated in the historic center of Puebla, a major city in the state of Puebla. As a large agglomeration, it plays a critical role in managing municipal wastewater for the region. The plant's designed capacity is 1.00, indicating its scale. In Mexico, wastewater treatment plants of this size are typically regulated under the National Water Law (Ley de Aguas Nacionales) and must comply with official standards (NOM-001-SEMARNAT-1996) for discharge quality. These standards mandate treatment levels appropriate for protecting receiving water bodies. The plant's discharge likely enters the Atoyac River, which flows through Puebla and is part of the Balsas River basin. The Balsas River ultimately drains into the Pacific Ocean. The Atoyac River is ecologically significant, supporting diverse aquatic life and providing water for agricultural and urban uses downstream. Proper treatment is essential to prevent pollution and maintain water quality in this important watershed.

Atoyac Sur discharges into the Atoyac River, which flows through Puebla and joins the Balsas River before reaching the Pacific Ocean. The Atoyac River basin supports a variety of aquatic ecosystems and is a critical water source for surrounding communities. Effective wastewater treatment is vital to protect these ecosystems from nutrient pollution and pathogens, especially given the plant's large service population.
