What is the minimum land area requirement for public water supply with Soil Type 3?

The minimum land area requirement for public water supply systems varies based on soil type, given that different soil types exhibit varying characteristics that affect water filtration, drainage, and the overall effectiveness of the system. For Soil Type 3, which is typically characterized as moderate permeability, the minimum land area that is mandated ensures that there is adequate space for properly managing the water supply and mitigating contamination risks. In this case, the requirement of 22,000 square feet is established to ensure effective operation and maintenance of the water supply system.

While other options might suggest different land area requirements, they do not align with the specific standards set for Soil Type 3. It is essential to understand the reasoning behind the regulations, as they aim to protect public health by maintaining a safe and reliable water supply. Adequate land area ensures enough buffer space to absorb potential contaminants and maintain the quality of the water being supplied.
