In environmental planning of a rural subdivision, what basic information is crucial in determining the feasibility of individual water and sewage systems on each home site?

Determining the feasibility of individual water and sewage systems for homes in a rural subdivision heavily relies on the size of the lot. This is crucial because appropriate space is necessary to accommodate both the water supply system and the sewage disposal system, such as a septic system.

A larger lot size generally provides more flexibility in siting these systems, ensuring that there is adequate distance from dwellings, property lines, and any potential contaminants, like livestock or surface water sources. Additionally, the lot size impacts the ability to meet local zoning and health regulations, which often include requirements for minimum distances between the septic systems and water sources or property boundaries.

In contrast, while other factors listed offer insights into specific components of the systems, like the sanitary code or the characteristics of water wells and septic tanks, they do not encompass the overall spatial considerations that the lot size entails for proper installation and function of water and sewage systems.
