Which of the following factors must be indicated on subdivision plans related to onsite wastewater systems?

Indicating the presence of streams, wells, and pipelines on subdivision plans related to onsite wastewater systems is crucial for several reasons. This information is essential for assessing environmental impacts, ensuring proper separation distances, and complying with local regulations governing the placement and operation of wastewater systems.

The proximity of streams and wells is particularly important as they can be directly affected by wastewater runoff or potential contamination. Properly mapping these features helps in designing systems that reduce the risk of pollution and safeguard water quality for both public health and environmental sustainability. Additionally, the presence of pipelines can influence the placement of wastewater systems to prevent any possible interference or hazards.

Recognizing this factor ensures that developers and planners are considering all necessary health and safety measures, as well as adhering to regulations that aim to protect water resources. By focusing on environmental factors crucial to wastewater management, the plans can better adhere to best practices and regulatory compliance, leading to safer, more sustainable development.
