What is a necessary precaution to protect the reserve area of a mound system during construction?

The use of a temporary fence or barrier is crucial for protecting the reserve area of a mound system during construction. This precaution helps to clearly delineate the area that must remain undisturbed, which is essential for the proper functioning of the mound system. The reserve area is set aside for future expansion or repair, and keeping it free from construction activities and equipment prevents damage to the soil and prevents compaction, which can lead to a reduction in the area's ability to adequately filter and absorb wastewater.

Other approaches, such as using heavy machinery, conducting construction at any time, or allowing unrestricted access to the area, would pose risks by potentially harming the reserve area. Heavy machinery can compact the soil or disrupt its structure, leading to inadequate treatment of effluent. Similarly, unrestricted access without proper guidelines or barriers increases the chance of accidental damage to critical components of the mound system. Properly protecting the reserve space ensures that it remains functional and capable of serving its intended purpose when needed in the future.
