A septic tank is a large container used to collect sewage from homes. They’re typically buried beneath the ground and contain several feet of soil. Septic tanks are made of reinforced concrete, fiberglass, or polyethylene. Their size ranges from five gallons up to ten thousand gallons.
The average household uses about four hundred gallons of water per day. This amount of water goes down the drain every day and ends up in the sewer. As it travels through the plumbing, bacteria break down waste products into liquid and solid matter. When the sewage reaches the septic tank, the solids settle out while the liquids flow into the tank.
In some cases, the tank is partially filled with gravel or pebbles to help speed up the process. Once the tank is full, the contents must be pumped out regularly. This helps prevent overflow during heavy rains.
When the tank becomes clogged, the sewage cannot pass through the gravel and gets backed up inside the house. If you smell a foul odor coming from your home, it could mean there’s a problem with your septic tank.
It is important to inspect your septic tank annually. Septic system evaluation includes checking for leaks, cracks, general wear and tear, and any damage to your tank. Regular checkups help prevent expensive repairs later on.
