Tying a garbage disposal into a sewage system primarily causes an increase in what?

Tying a garbage disposal into a sewage system primarily causes an increase in solids. When food waste is processed through a garbage disposal, it is ground up into smaller particles before being flushed into the sewage system. This grinding action creates a significant volume of solid waste that can lead to increased solids in the sewage system.

The addition of these solids can have implications for the sanitation system, such as contributing to clogs and requiring more frequent maintenance. Sewage systems are designed to handle both liquid waste and solids; however, an influx of ground food waste can challenge the system's capacity to manage solids effectively, especially if the particles are too large or numerous.

While garbage disposals also contribute to liquid waste as they allow food waste to be mixed with water before entering the sewage system, the primary concern is the increase in solid materials because they may not break down as easily as liquid waste. Hence, the connection between garbage disposals and an increase in solids is vital for understanding their impact on sewage systems.
