How should reverse osmosis waste be discharged?

Into a storm drain
Straight into the septic system
Indirectly wasted with an air gap
Into a potable water supply

The correct answer is: Indirectly wasted with an air gap

The correct method for discharging reverse osmosis waste is through indirect waste with an air gap. This approach is crucial for protecting the drinking water supply from potential contamination. An air gap serves as a physical barrier that prevents any backflow of water, ensuring that wastewater from the reverse osmosis process cannot siphon back into the potable water system. In reverse osmosis systems, water is filtered to remove impurities, and the waste produced contains high concentrations of these contaminants. Directly discharging this waste into systems such as a storm drain or a septic system can lead to environmental pollution or interfere with the proper functioning of the septic system. Furthermore, discharging waste into a potable water supply is strictly prohibited due to health risks associated with cross-contamination. Therefore, utilizing an indirect waste method with an air gap is not only a best practice but often required by plumbing codes to safeguard public health and maintain the integrity of the water supply system.
