What is the required radius for a restricted zone around the raw water intake?

The required radius for a restricted zone around a raw water intake is established to protect the water source from potential contaminants and ensure the safety of the drinking water supply. In Texas, the standard radius for this restricted zone is typically set at 200 feet. This distance is considered adequate to mitigate the risks associated with contaminants that could enter the water supply from surrounding areas, including recreational activities, agriculture, or nearby developments.

Establishing such a zone helps maintain the quality of the raw water, ensuring that any potential sources of pollution are kept at a safe distance from where the water is drawn for treatment and distribution. The specific regulations are aligned with public health and safety standards that aim to safeguard water resources effectively.
