For longer holding times, latrine will be required to construct?

• A. 50 foot deep latrines with 2 holes
• B. 100 foot deep latrines with 2 holes
• C. 200 foot deep latrines with 4 holes
• D. 100 foot deep latrines with 4 hole latrines

Answer: (D)

For longer holding times, the design should maximize capacity and distribute use to prevent quick filling and reduce odor and contamination risk. A deeper latrine pit holds waste longer and reduces the frequency of servicing, while having more holes increases overall throughput, spreading usage and preventing stampede in a single hole. The combination of a 100‑foot-deep pit with four holes provides both the needed storage capacity and the higher throughput to accommodate extended holding periods. The other options either offer less depth (reducing storage duration) or fewer holes (reducing throughput), or are more extreme than necessary. Therefore, 100 feet deep with four holes best meets the need for longer holding times.
