All liquid waste must be discharged into which system?

• A. Storm drain
• B. Private septic system
• C. Public sewer
• D. Direct discharge into a river

Answer: (C)

Waste from esthetic practices must be directed to a system that treats it before it enters the environment. The public sewer is designed to collect and send wastewater to a treatment facility, where contaminants are removed and regulations are enforced. Directly releasing liquid waste into a storm drain or a river would bypass treatment and violate environmental and health protections. A private septic system could be an option only if the facility has a properly designed, permitted septic system and is compliant with local health and plumbing codes; it isn’t universally applicable to every setup. So, the standard and safest route for liquid waste is the public sewer.
