What depth must a privy be dug?

1. 1 to 2 feet

2. 2 to 3 feet

3. 3 to 5 feet

4. 5 to 7 feet

The correct answer is: 3 to 5 feet

The depth of a privy is significant for several reasons, particularly in the context of proper containment of waste and the prevention of contamination. The correct depth of 3 to 5 feet ensures that the privy is sufficiently below the surface to minimize the risk of surface runoff and seepage that could contaminate groundwater or surrounding soil. At this depth, the privy is also positioned to take advantage of natural decomposition processes, aiding in the breakdown of waste materials. Additionally, this depth helps to contain odors and serves to protect the privy from flooding and other issues that may arise with shallower excavations. Choosing a depth beyond this range could lead to practical issues, such as difficulty in excavation and maintenance, while insufficient depth would not adequately protect against the environmental hazards mentioned. Thus, digging a privy to a depth of 3 to 5 feet aligns with best practices for ensuring sanitary conditions and environmental safety.
