Subdivision plans that involve individual wells and sewage disposal systems must be adapted to the topography and geological formations existing because these factors directly influence the functionality and safety of such systems. Proper adaptation ensures that the placement and design of wells and sewage systems take into account the natural contours of the land, soil types, drainage patterns, and potential contamination sources.

When well and sewage systems are aligned with the unique characteristics of the land, it minimizes risks such as groundwater contamination and system failure. For example, in rocky terrain, different drilling techniques may be required for wells, while areas with high water tables may necessitate special considerations for sewage systems to prevent backups or contamination. Hence, adapting these systems to local geological and topographical conditions is essential for environmental health and the sustainability of the water and waste management systems in the subdivision.
