What is the specified distance for public water supply lines from soil absorption systems as per regulations?

The specified distance for public water supply lines from soil absorption systems is 10 feet, as this distance is crucial for preventing contamination of the water supply. This regulation is in place to protect groundwater and ensure that any effluent from the soil absorption system does not pose a risk to the integrity of the public water supply. Maintaining this minimum separation helps to reduce the likelihood of pathogens or pollutants infiltrating the water supply, thereby safeguarding public health.

The distance is chosen based on hydrological studies and practical experience that demonstrate a sufficient buffer zone to allow for the proper treatment of wastewater before it has any chance of reaching a water supply line. The regulatory framework established by TCEQ emphasizes the importance of following these guidelines to maintain safe drinking water and protect public health.
