Final answer:
It is true that it is unlawful to dispose of sewage or liquid wastes without proper connection to a drainage system. Proper sewage disposal is critical to prevent environmental contamination and protect public health.
Step-by-step explanation:
It is true that it shall be unlawful for a person to permit the disposal of sewage or other liquid wastes not properly connected to a drainage system. Proper disposal and treatment of sewage are essential to prevent water pollution and protect public health. Sewage systems have evolved significantly throughout history, but the end goal remains consistent: to transport and treat wastewater effectively to prevent it from contaminating water sources and the environment. For example, a combined sewer system can become a major point source of water pollution if it overflows during heavy rain, discharging untreated sewage directly into nearby water bodies. Historically, the Great Stink in London during 1858 illustrated the dangers of inadequate sewage disposal, leading to the redesign and improvement of sewer systems. Modern-day septic systems in rural and suburban areas also illustrate the need for properly maintained personal wastewater treatment facilities. Thus, ensuring sewage is disposed of via legally compliant drainage systems is critical and mandated by law.
