Overview
Puebla San Francisco wastewater treatment plant serves approximately 545,000 people in Puebla, Mexico. The facility operates under Mexican water quality regulations for municipal wastewater.
Puebla San Francisco is a major wastewater treatment plant located in the historic center of Puebla, Mexico. Serving an estimated 545,480 residents, it is a key component of the city's sanitation infrastructure, managing a significant portion of the municipal wastewater generated in this densely populated urban area. As a large-scale facility, Puebla San Francisco is expected to comply with Mexico's official standards for wastewater treatment (NOM-001-SEMARNAT), which set discharge limits based on receiving water body characteristics. Plants of this size typically employ secondary or advanced treatment to meet regulatory requirements for organic matter and solids removal. The treated effluent from Puebla San Francisco ultimately discharges into the Atoyac River basin, which flows through the state of Puebla and is part of the larger Balsas River watershed. The Atoyac River is ecologically significant, supporting diverse aquatic life and providing water for agricultural and industrial uses downstream. Proper treatment at this plant is crucial for protecting water quality in this heavily utilized river system.
Environmental context
Puebla San Francisco discharges into the Atoyac River, a tributary of the Balsas River, which flows into the Pacific Ocean. The Atoyac River basin faces pressures from urban and industrial runoff, making effective wastewater treatment essential for maintaining water quality. The river supports a variety of fish species and provides irrigation water for surrounding agricultural areas, highlighting the plant's role in safeguarding downstream ecosystems and human uses.
