The relatively grease-free water is then fed into the normal septic system.The food solids at the bottom and floating oil and grease must be periodically removed in a manner similar to septic tank pumping. [11] A traditional grease trap is not a food disposal unit. Unfinished food must be scraped into the garbage or food recycling bin.
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
The garbage disposal is also notable as a septic-compatible choice. As long as your septic tank is well maintained, the disposal should work easily with it, without giving your plumbing any issues ...
Earlier, the waste disposal system had consisted of collecting waste and dumping it on the ground or into a river. Eventually the development of separate, underground water and sewage systems eliminated open sewage ditches and cesspools .

A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater flows for basic sewage treatment. [2] Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment"). [2]
Septic tank and septic drain field. Septic drain fields, also called leach fields or leach drains, are subsurface wastewater disposal facilities used to remove contaminants and impurities from the liquid that emerges after anaerobic digestion in a septic tank. Organic materials in the liquid are catabolized by a microbial ecosystem.
In the United States, 50% of homes had disposal units as of 2009, [12] compared with only 6% in the United Kingdom [13] and 3% in Canada. [14]In Britain, Worcestershire County Council and Herefordshire Council started to subsidize the purchase of garbage disposal units in 2005, in order to reduce the amount of waste going to landfill and the carbon footprint of garbage runs.
