According to soil type descriptions, what soil is classified as Soil Type 1?

Soil Type 1 is classified as Gravelly and very gravelly coarse sands due to its high permeability and relatively low water retention capacity, which makes it suitable for septic system drain fields. The characteristics of this soil type allow for efficient drainage, reducing the risk of saturated conditions that can impede the function of septic systems.

Gravelly soils have larger particles that create more void spaces, facilitating the movement of water through the soil. This attribute helps prevent waste from pooling in the area surrounding the septic system. Proper understanding of soil classifications is crucial for installing septic systems, as soil type directly affects the system’s performance and longevity.

In contrast, other soil types such as medium sands, coarse sands, and clayey soils do not exhibit the same properties as Gravelly and very gravelly coarse sands. Medium and coarse sands might still allow for some drainage but do not offer the same level of efficiency as the gravelly variant, while clayey soils retain water and can lead to saturation and system failure.
