Which type of sewer system is not directly controlled by a public authority?

• A. Municipal Sewer
• B. Private Sewer
• C. Public Sewer
• D. Community Sewer

Answer: (B)

The key idea is ownership and who runs the system. Public authorities directly manage sewers that are part of the public infrastructure—municipal, public, or community sewers—since these networks are owned and operated by the city, district, or utility, with standards and maintenance carried out by that public entity. A private sewer, however, is owned by a private party—typically a property owner or a homeowners’ association—and is not directly controlled by the public authority. The private owner is responsible for its upkeep and repairs, while the public authority still enforces applicable codes and oversees connections to public facilities. So the private sewer is the one not directly under public control.
