What is the minimum horizontal distance between a water supply well and the building sewer?

50 feet
100 feet
10 feet
15 feet

The correct answer is: 50 feet

The minimum horizontal distance between a water supply well and the building sewer is crucial for protecting the water supply from potential contamination. The 50 feet requirement is established to ensure that any contaminants from the sewer do not have the opportunity to seep into the groundwater or the well. This distance helps to mitigate risks from potential leaks or failures in the sewer system, as well as from surface runoff that could carry pollutants toward the well. Maintaining this distance is a standard practice in plumbing and environmental safety regulations, emphasizing the importance of safeguarding potable water sources. It's worth noting that factors such as soil type, local regulations, and the specifics of the site can also influence these requirements. However, generally speaking, a distance of at least 50 feet is recognized as the minimum safe standard for the separation between a water supply well and a building sewer.
