What authority is allowed to appoint sewage system inspectors according to the relevant provisions?

The correct answer indicates that the Council of an upper-tier municipality holds the authority to appoint sewage system inspectors. This power is essential for ensuring that sewage systems comply with local and provincial regulations, which aim to protect public health and the environment.

Upper-tier municipalities typically oversee large geographic areas comprised of several lower-tier municipalities. By assigning inspectors to monitor sewage systems, they can maintain standards that promote safety and efficiency in sewage management. The appointment of inspectors through a formal council process ensures oversight by elected officials, which adds a layer of accountability and governance to the management of sewage systems.

In contrast, local school boards, private contractors, and city planning departments do not possess the same level of authority regarding the appointment of inspectors for sewage systems. Local school boards primarily focus on educational facilities, while private contractors may offer services but lack the official capability to appoint inspectors. City planning departments, although involved in land use and development, do not independently hold the authority designated specifically for sewage system inspection appointments.
