Arizona Plumbing Practice Exam

What is the minimum horizontal clear distance required between seepage pits?

1. 6 feet

2. 8 feet

3. 10 feet

4. 12 feet

The correct answer is: 12 feet

The minimum horizontal clear distance required between seepage pits is established to ensure proper drainage and to prevent contamination of groundwater. A distance of 12 feet helps to minimize the risk of one pit's effluent negatively impacting another’s operation. This clear space allows for adequate absorption and treatment of wastewater in each pit, reducing the likelihood of saturation or overflow, which can lead to environmental hazards and health risks. This standard is based on environmental considerations and plumbing codes that govern safe and effective wastewater management practices. The emphasis on a greater distance reinforces the importance of maintaining a healthy and sustainable plumbing system. This distance ensures that any effluent from one seepage pit has minimal chance of affecting the effluent handling capabilities and the overall function of adjacent pits.
