All home waste drains into a septic tank, which is held long enough for solid and liquid waste to separate by settling and flotation. Oils and grease float to the top and form a layer called scum, while bacteria break down solid waste at the bottom. The clarified wastewater that flows out of the septic tank is called effluent.

Septic tank ownership is a major investment for homeowners. Depending on the size of your home and how many people live in it, the cost of a septic system can range from $3,600 to $10,000. Additional factors like a soil survey, percolation test, and permits can also increase costs.

A septic tank stores wastewater from household plumbing until it is emptied into the absorption field. This allows solids to settle and float before they are released into the soil. Heavy solids, such as sludge and fats, settle at the bottom of the tank while lighter solids, including human waste and toilet paper, float to the surface, where bacteria decompose them. Once the wastewater is clear, it is pumped into the drain field through a distribution box.

The drain field is a series of perforated pipes in porous gravel that absorbs the wastewater from the septic tank and filters it before reaching groundwater. The drain field is also designed to help with nutrient and pollutant removal. Alternatively, some alternative systems use pumps or gravity to help septic tank effluent trickle through sand, organic material (e.g., peat and sawdust), constructed wetlands or other media to remove disease-causing pathogens and reduce nitrogen, phosphorus and other contaminants before it is discharged into the soil.

It is recommended that a septic tank be inspected and pumped every three to five years. This will ensure that the septic system is working properly and preventing sewage from overflowing into your home. It is also important to keep in mind that your septic tank will need to be pumped sooner if the family’s wastewater production increases dramatically or if the septic system is overfilled.

When septic tanks need to be pumped, a professional will bring a truck that has a giant tank with a suction hose attached. The hose will be lowered into the tank to pump out the sewage, which is then taken away to be disposed of in a sanitary sewer system. The cost of septic tank pumping is $500-$1,800 for a septic tank that holds between 300-1,000 gallons.

Maintenance

Whenever someone uses the toilets, bathes, or washing machines at your home, wastewater flows through the house’s drain field into the septic tank. Wastewater in the septic tank goes through a process of settling and flotation, which results in three different layers in the tank: scum, sludge, and effluent. Substances lighter than water, such as oils and grease, float to the top of the tank and form a layer called scum. Aerobic bacteria inside the septic tank digest these floating solids. Substances that are denser than water, such as grit, bones, and unconsumed food particles, settle to the bottom of the tank and form a dense layer known as sludge. Anaerobic bacteria in the sludge layer decompose these materials, giving off gases. The liquid wastewater in the middle of scum and sludge is known as effluent.

Keeping up with maintenance will help keep your septic system operating efficiently for as long as possible. One important tip is to avoid flushing anything other than human waste and toilet paper. Items such as feminine hygiene products, baby wipes, cat litter, and coffee grounds can clog toilets and the septic tank. Also, it is a good idea to reduce the amount of water used in the household by using gadgets like toilet displacers and faucet aerators.

Another important maintenance tip is to have the septic tank pumped regularly. Having the tank pumped will help prevent the drainfield from failing and prevent contaminants from leaching into groundwater. You can do this by calling a professional who is licensed to inspect, measure tank layers, and pump the septic tank.

It is also important to keep up with septic tank cleanings, and have the septic tank vent properly maintained. Venting allows gasses to escape the septic tank and into the drainfield, where they are absorbed by surrounding soil. If a vent is blocked, the septic tank will become full and will need to be pumped out sooner.

Lastly, the septic tank drainfield should be protected from vehicles or other sources of water that can flood it. Cars can add unnecessary weight that can damage the drainfield, and trees or plants can grow around and block drainpipes. It is also a good idea to have the tank inspected regularly by a professional who can spot problems and make recommendations for repairs.

Environment

A septic tank is a buried, water-tight container that holds household wastewater for an extended time. This gives it time to separate solids and liquid wastes. The heavy materials sink to the bottom forming sludge, while fats and oils float to the top forming a scum layer. Aerobic bacteria digest the scum and sludge. The result is a clear, liquid layer known as effluent. The wastewater leaves the septic tank through a watertight outlet pipe and travels to a soil absorption field.

All the wastewater from your house’s toilets, showers, kitchen drains, washing machine, and garbage disposal enters your septic system. During this process, the waste is partially treated by bacteria before it goes into your septic tank. There are also septic tank treatment products on the market that claim to restore bacterial balance and keep your septic system working properly. However, these products can harm the bacterial ecosystem in your septic tank and may cause problems. Talk to your plumber to find out what products are safe for your septic system.

The wastewater that flows from your home’s plumbing into your septic tank is a mixture of human and kitchen waste. When the septic tank fills up, the waste separates into three distinct layers. The first layer consists of anything that floats, including oils and grease. The second layer is the wastewater, and the third layer consists of things that are heavier than water. The septic tank contains bacteria that decompose the waste and break it down into liquid.

Once the septic tank reaches capacity, it will need to be emptied. If the septic tank is not emptied in time, it will overflow and flood the surrounding soil and cause sewage to back up into the toilets. If you suspect your septic tank is full, hire a professional to pump it.

A septic tank is designed to work with a drainfield, which is a field of perforated pipes that extend into the soil. The pipes are surrounded by gravel and the soil is covered with a layer of biomat. The biological mat provides the main purification for the septic tank effluent. In addition, the septic tank also relies on natural filtration.

Safety

A septic tank system is designed to remove pollution and release treated waste water into the environment. But if the system is poorly constructed and maintained, it can pollute groundwater and household wells with bacteria. This can affect the health of infants, pregnant women, and the elderly. It can also cause diseases such as typhoid fever, hepatitis, and dysentery.

The most common problem with septic systems is the accumulation of solid materials in the drainfield. This can lead to system failure and clogs. The best way to prevent clogs is to have the tank pumped regularly. In addition, you should divert down spouts and other surface water away from the drainfield.

Septic tanks should always be fenced and marked. Curiosity among children and pets can cause dangerous accidents around the tank, including falling into or being overcome by toxic gases. The tank lids and risers should be secured with a lock that requires a key or combination to open, as these can also pose safety risks.

A poorly ventilated septic tank can produce methane gas, which is highly toxic and explosive. It is also a fire hazard and can cause burns or other injuries. The tank should be kept at least five feet from all open flames and other potential sources of ignition. This includes candles, cooking equipment, and cigarette lighters.

The decomposition of sewage in the tank releases harmful bacteria that can cause diseases and infections. These bacteria can enter household wells, contaminating drinking water. They can also contaminate the surrounding soil and groundwater. This can cause illnesses such as hepatitis, typhoid fever, and diarrhea. They can also affect the health of newborns, causing blue baby syndrome, which is caused by a lack of oxygen in the blood.

It is not safe to enter a septic tank, even if the level of scum and gunk has reached the outlet drain. Inhaling the fumes can be dangerous, and leaning over the opening can cause suffocation. It is important to have a professional inspect and pump the septic tank regularly. The water that exits the tank should be fully filtered before entering the groundwater supply. This will reduce the risk of contaminating the wells and soil.
