Will coffee grounds hurt a septic tank?

Yes, coffee grounds are bad for septic systems because they don't easily break down, leading to sludge buildup, clogged pipes, potential drain field issues, and disruption of the tank's bacterial balance due to their acidity, meaning they should be avoided or disposed of in compost instead. While a tiny amount in water might be okay, dumping them down the sink or toilet acts like adding gravel, increasing solids and requiring more frequent pumping.
