If a sewer is not available, the house drain shall be connected to an approved _________ _________ _________.

• A. Septic tank
• B. Public sewer line
• C. Sewage disposal system
• D. Storm sewer

Answer: (C)

If a sewer is not available, the sanitary waste from the house must go to an approved on-site solution rather than trying to drain somewhere else. The three-word fill-in points to the general term “sewage disposal system,” which covers on-site methods like septic tanks and other approved arrangements. A septic tank is a specific type of sewage disposal system, so the broader label is the correct fill. Public sewer lines would only apply if a municipal sewer is accessible, and a storm sewer handles only rainwater, not sanitary waste. Therefore, connecting to an approved sewage disposal system best fits the requirement.
