Which statement accurately reflects the minimum extension for distribution piping in a conventional leaching bed when the calculated length is 35 m?

Which statement accurately reflects the minimum extension for distribution piping in a conventional leaching bed when the calculated length is 35 m?

• A. 30 m
• B. 35 m
• C. 40 m
• D. 45 m

Answer: (C)

A conventional leaching bed requires a minimum extension for distribution piping beyond the calculated length to ensure proper flow distribution and to account for practical installation factors. The rule is to add 5 meters to the calculated length as the minimum extension. With a calculated length of 35 meters, extending to 40 meters meets that minimum. The 30-meter option would be too short to satisfy the extension requirement, while sticking with 35 meters doesn’t meet the minimum extension. Extending to 45 meters would be longer than necessary to meet the minimum, but the question asks for the minimum extension, which is 40 meters.
