When septic systems begin to fail, your waste will start to seep into the groundwater. You may notice a foul odor (it’ll smell like sewage) or a squishy, moist lawn. The grass right over your tank or drain field might grow super lush and green because your waste actually fertilizes it. Other signs include standing water in your drain field, slow-draining sinks and tubs, and gurgling noises in the plumbing.

Pumping involves opening the tank lid, removing solids and wastewater, and inspecting components for wear or damage to maintain optimal function.

Your garbage disposal will only affect the health of your septic tank if you’re using it too frequently, or filling it with organic waste that doesn’t fully break down. If the tank fills up with too many solids, the bacteria won’t have enough time to consume it before more is added, which can lead to an overflow in the drain field. Your tank will need to be pumped more frequently with excessive or improper garbage disposal use.

Disposing of old paint, bleach, oil, and fertilizer should be handled by a company that specializes in this kind of waste. Many private junk removal companies do not dispose of these items. Because these materials are hazardous to the environment and dangerous to handle or dispose of improperly, you should confirm with your local municipality about places to take hazardous materials for safe disposal.
