What should an inspector look for when locating drain fields?

When locating drain fields, it is essential for an inspector to consider areas of lush vegetation and areas of depression. Lush vegetation often indicates a good level of moisture in the soil, which is significant because drain fields rely on the soil's ability to filter and absorb wastewater. Where there is healthy, green growth, it suggests that the soil may have the necessary permeability and capacity to handle the effluent being distributed.

Additionally, areas of depression are critical because they can serve as natural basins for water accumulation. However, they may not always be suitable for drain fields if they lead to water pooling significantly, as this can create saturation issues. Thus, an ideal location for a drain field combines the right moisture levels indicated by vegetation and the drainage characteristics suggested by the topography.

In contrast, while flat, even surfaces and dry, sandy soils may seem appealing, they do not account for critical factors like soil saturation and drainage capability needed for effective waste filtration. Areas uphill may suggest improved drainage but do not guarantee suitable conditions for a drain field's operation, as water must flow downhill to enter the system effectively. Therefore, finding areas with lush vegetation and depressions is more indicative of an appropriate site for drain fields.
