Project Details
The project titled “Construction and Commissioning of Sewer Collectors and Wastewater Treatment Plant (WWTP) in Zamora, Tangancícuaro, Chilchota, and Ixtlán for the Sanitation of the Duero River” aimed to significantly improve wastewater management and environmental protection in the state of Michoacán, Mexico. The treatment plant was designed to process the wastewater generated by the municipalities of Zamora, Tangancícuaro, Chilchota e Ixtlán before its discharge into the Duero River.
Design Life: 20 years
Application of Atarfil Geomembranes
Atarfil HDPE geomembranes were specifically chosen for their reliability and durability, crucial for wastewater containment and environmental protection. These geomembranes were applied extensively throughout the treatment facility, including:
- Facultative lagoons
- Maturation lagoons
- Sludge drying beds
- Anaerobic reactors (RAFA)
Installation and Specifications
- The interconnection pipelines utilised HDPE RD-41 pipes thermofused for seamless and leak-proof integration.
- Stub-end flanges with steel backing were used for connections to treatment structures, ensuring robust and long-lasting joints.
- Gate valves with iron bodies were installed for operational control.
- Concrete thrust blocks were strategically placed at pipeline direction changes (≥45° angles) to ensure the stability and integrity of the geomembrane installations.
Benefits Achieved
- Long-term wastewater containment without leaks, protecting the surrounding environment from contamination.
- Reduction in maintenance costs and increased lifespan due to the high durability of Atarfil geomembranes.
- Enhanced operational efficiency, ensuring consistent performance under variable flow conditions.
Conclusion
The project successfully met its goal to improve wastewater management and contribute positively to the environmental sanitation of the Duero River, aligning with sustainability objectives and setting a benchmark for future wastewater projects in the region.
Atarfil’s HDPE geomembranes have provided the project with superior long-term containment and durability, demonstrating the importance of selecting high-quality materials in critical environmental infrastructure projects.
