Why did waste collection become a public health problem in Rome?

Waste collection became a public health problem in cities like Rome due to the historical reliance on crude disposal methods that failed to manage the accumulation of refuse. In ancient Rome, property owners were responsible for cleaning the streets in front of their homes, but there was no comprehensive, organized municipal waste collection system for daily refuse.1

When waste is not properly managed, it creates significant risks to public health. Historically, waste was often deposited in open pits or left to accumulate on streets, which served as breeding grounds for disease-carrying pests such as rats, flies, and mosquitoes. Furthermore, the decomposition of organic waste produces unpleasant odors and hazardous by-products like methane and leachate, which can contaminate soil and groundwater if not contained within engineered sanitary landfills. The failure to implement systematic collection and sanitary disposal practices inherently jeopardizes environmental quality and human well-being.21
