In Scenario I of the wastewater evaluation, which element is assumed not feasible?

• A. Piping
• B. Soakaway
• C. Septic Tank
• D. Cesspool

Answer: (A)

In this scenario, what’s being tested is feasibility of wastewater paths. When evaluating options, you first check whether a municipal or centralized sewer connection (piping to a sewer) is even possible. In Scenario I, that connection is assumed not feasible—perhaps due to no available sewer service, excessive distance, or prohibitive cost. Because a sewer connection isn’t an option, the element that is considered not feasible is the piping to a sewer, which makes on-site disposal options like soakaways, septic tanks, or cesspools the relevant alternatives to evaluate for the site conditions.

Soakaways, septic tanks, and cesspools are all on-site disposal or treatment options that could be considered once off-site piping to a sewer is ruled out. The choice here reflects the scenario’s constraint rather than the intrinsic suitability of those on-site options.
