An Aerobic Treatment Unit (ATU) requires special installation because of its unique system that enhances the treatment of wastewater through aerobic digestion. Unlike conventional septic systems, which rely primarily on anaerobic processes, an ATU requires specific setup procedures to ensure the proper aeration of wastewater, which is crucial for effective treatment.

The special installation involves considerations such as proper leveling, aeration equipment setup, control panel installation, and electrical connections. These units must be carefully integrated into the existing plumbing and drainage systems, and they often come with manufacturer specifications that must be strictly followed to ensure optimal performance and compliance with local regulations.

The installation process usually involves trained professionals who understand the complexities of the system and can ensure it functions appropriately. This attention to detail during installation is vital to prevent issues like backups, inefficient treatment, or system failure, which could result from improper setup. Thus, it's essential to engage experienced personnel for an ATU installation instead of opting for standard methods, DIY approaches, or skipping installation altogether.
