The Rainwater and Sewage Treatment Plant at Andijan State Technical Institute is a modern facility designed to promote sustainable water management, environmental protection, and resource efficiency. The plant supports the institute's Green Campus initiative by integrating rainwater harvesting, wastewater treatment, and water reuse technologies into daily campus operations.

The facility incorporates an advanced rainwater harvesting system that captures and stores rainwater from rooftops and other impermeable surfaces across the campus.

The collected water is filtered and treated to meet quality standards before being reused for various non-potable purposes, including:

• Landscape and garden irrigation
• Toilet flushing
• Cooling systems
• General campus maintenance

This system reduces dependence on municipal water supplies while minimizing stormwater runoff, flooding, and soil erosion.

The sewage treatment plant utilizes a comprehensive multi-stage purification process consisting of:

1. Preliminary Screening
2. Primary Treatment
3. Secondary Biological Treatment
4. Tertiary Treatment and Final Purification

This treatment process effectively removes contaminants, producing treated wastewater that satisfies environmental discharge standards.

The treated water is safely reused for irrigation, cooling systems, landscaping, and selected industrial applications, supporting a circular water economy throughout the campus.

• Aquaponics systems
• Toilet flushing
• Cooling systems
• Garden irrigation and sprinkler systems
• Landscape maintenance

Water meters are installed to continuously monitor rainwater collection and recycled water consumption, enabling accurate reporting and efficient water resource management.

• Conserves freshwater resources.
• Reduces municipal water consumption.
• Minimizes stormwater runoff.
• Reduces soil erosion and water pollution.
• Supports sustainable campus operations.
• Promotes circular water resource management.
• Reduces the institute's environmental footprint.

The institute has a large number of professors, researchers, and students actively involved in research and educational projects related to wastewater treatment technologies, water reuse, environmental engineering, and sustainable water management.

The treatment plant serves as a practical learning laboratory where students gain hands-on experience with modern water treatment technologies while conducting research that supports innovation, sustainability, and environmental protection.
