If you are buying a home with a septic system for the first time, or if you are remodeling your kitchen, you might be wondering if you can keep or install a garbage disposal.
The Short Answer: Using a garbage disposal with a septic system is a recipe for disaster. Disposals grind up food waste and send it directly into your septic tank, rapidly increasing the accumulation of solid sludge and forcing you to pump twice as often.
The Biological Problem with Food Waste
The bacteria in your septic tank are excellent at digesting human waste and toilet paper. They are terrible at digesting food waste. Food waste sinks to the bottom and simply sits there, taking up space and accelerating sludge buildup by up to 50%.
Safe Alternatives
1. Mesh sink strainer (under $10).
2. Composting food scraps.
3. Scraping plates into the trash before washing.
The Bottom Line
A garbage disposal and a septic system are a terrible combination. Use a mesh strainer, compost your scraps, and maintain your drains monthly with a natural enzyme product.
