How does subsection (6) influence councils overseeing sewage systems?

Subsection (6) is significant because it requires councils that oversee sewage systems to ensure compliance with necessary modifications. This aspect emphasizes the councils' ongoing responsibility to adapt and modify existing systems to meet updated standards and regulations effectively. It recognizes that systems may require adjustments to improve their performance or to comply with evolving environmental and health regulations.

This compliance is essential for maintaining public health and safety, protecting water quality, and ensuring that sewage systems function properly. By mandating necessary modifications, subsection (6) ensures that councils are proactive in addressing any deficiencies or outdated practices within sewage systems. This allows for continuous improvement and assurance that these vital infrastructure components meet current operational and safety standards.
