What is one reason that automatic control systems are often not installed in water treatment plants?

Automatic control systems indeed play a crucial role in water treatment plants by enhancing operations, efficiency, and safety. However, the choice regarding the reduction of documentation is a notable point when considering why some plants opt not to install such systems.

The rationale behind option B is rooted in the fact that the implementation of automatic control systems can create a perception that reduces the need for extensive written documentation. While these systems can automate processes and generate data, they do not entirely eliminate the necessity for proper documentation in compliance with regulatory requirements and for operational audits. Documentation is essential for tracking system performance, maintaining regulatory compliance, and ensuring accountability. Treating this complexity with the perspective that documentation requirements can be reduced may lead to oversight in critical areas.

This perception of lessened documentation needs might contribute to hesitance in adopting automatic control systems due to the potential underestimation of the role documentation plays in supporting operations and ensuring safe and reliable water treatment processes.
