InSinkErator® garbage disposals are tough on food waste, yet easy on properly maintained septic systems. Our disposals work with your septic tank to help manage food waste effectively, leaving you with a fresh, clean kitchen – all while diverting food waste from landfills.
A garbage disposal grinds food waste to easily flow through a home's plumbing and into a septic tank. Because food scraps are 60% to 95% water, they add very little to the solids that settle at the bottom of the tank. Studies show that septic systems attached to a garbage disposal don't require more frequent pumping than those that aren't.1
