Which of the following is NOT a rule of water discipline?

The focus on water discipline is crucial for maintaining health and hygiene in field sanitation. Drinking only approved water ensures that the water consumed is safe, minimizing the risk of waterborne diseases. Preventing water waste is essential for sustainability and ensures that clean water resources are available for everyone. Protecting water sources with good sanitary practices helps to keep those sources free from contamination, further promoting public health.

On the other hand, reusing wastewater in cooking is not a practice that aligns with the principles of water discipline. Wastewater can contain contaminants and pathogens that pose serious health risks if ingested. Therefore, ensuring that only safe and clean water is used for cooking and drinking is vital for preventing illness and maintaining a healthy environment. This practice protects individuals and communities by adhering to guidelines that prioritize safety and sanitation.
