What action should be taken to reduce the introduction of solid waste into a sewage system?

To effectively reduce the introduction of solid waste into a sewage system, limiting the use of garbage disposals is an important measure. Garbage disposals grind up food waste, which then becomes part of the sewage system. This increase in solids can lead to clogs in pipes, overburden sewage treatment facilities, and contribute to higher maintenance costs and potential environmental issues. By encouraging households to reduce their reliance on these disposals, the volume of solid waste entering the sewage system is minimized.

Other options like increasing water usage or installing a septic tank may not directly address the issue of solid waste entering the municipal sewage system. Creating a composting system, while environmentally beneficial, could be considered a separate measure, aimed at managing organic waste rather than directly influencing the impact of garbage disposals on the sewage system. Through limiting garbage disposal usage, a more immediate and effective reduction of solid waste can be targeted, thereby helping maintain the integrity and efficiency of sewage systems.
