Final answer:
The statement is true; waste pipes carry sewage, including both greywater and blackwater, to sewer systems for treatment. Efficient waste pipe engineering helps in proper sewage management and pollution prevention.
Step-by-step explanation:
The statement that the discharge from clinical sinks and conveyed to the building drain is defined as a waste pipe is true. Waste pipes are the pipes that carry greywater (from sinks, showers, kitchens, etc.) and blackwater (containing human waste from toilets) away from fixtures and into the building drainage system. This system ultimately transports the wastewater to a treatment plant or disposal area. Understanding how these waste systems work is critical in the fields of engineering and health to ensure the proper handling and treatment of sewage to prevent pollution and safeguard public health.
In a broader context, wastewater includes not just sewage from residential sources but also from industrial and agricultural processes. It is treated at wastewater treatment plants, where contaminants and solids are removed. After treatment, wastewater can sometimes be repurposed for irrigation and landscaping, showcasing the importance of efficient waste pipe systems in the sustainability and environmental impact of waste management.
