Septic tank pumping is when a septic system professional will pump out all of the solids, scum, grease and liquid effluent from your septic. According to the Environmental Protection Agency, homeowners should have their tank pumped every three to five years to empty it.
Routine maintenance
The EPA recommends you get your tank inspected every 2-3 years. Some states in the US or counties have more stringent regulations that require a septic system professional to service your septic system and drain field pipes sooner.
1 - Septic tank is backing up
Every drain in your home is connected directly to your septic system. When your septic system fails or is filled to capacity, no more sewage or wastewater will enter the tank. Because no more effluent and wastewater can enter your tank, it will back up backing up into the household plumbing including sinks, drains, shower and your toilet.
2 - Gurgling noise in your pipes
While noises are usual when wastewater enters your plumbing system, gurgling sounds are not normal when you flush the toilet or have a shower. Gurgling noises often mean there is a blockage (from e.g.

When your septic system is overflowing you will see either pools of water or dampness near the tank or drain field, the grass near your tank is greener than the rest of the yard, or you will have slow drains or sewage backup into the house.
Why does my septic system fail?
A common reason for septic system failure is overloading the system with more water than it can absorb. A septic system is designed for a specific wastewater flow rate based on the number of bedrooms (120 gallons per bedroom per day) in the house served by the system. When this flow rate is exceeded, the excess water backs up into the house or surfaces in the yard. This problem is often the result of a leaky fixture: either a toilet that has a slow leak or a dripping faucet. A change in water use, such as more people in the house or the addition of a water-using appliance, such as a dishwasher or washing machine, may add additional water to your septic system. Further problems can arise if a sump pump, icemaker, or dehumidifier drains into the septic tank. Each of these devices can add excess water and should not be connected into your septic system.
How to tell if a septic system is failing?
How do you know if your septic system is failing? First, answer the following questions: 1 Do your drains empty slowly for reasons other than old, clogged pipes? 2 Does sewage back up into your house? 3 Have you noticed a wet, smelly spot in your yard? 4 Is your septic tank piped to a ditch or stream? 5 Is your washing machine or sink piped to a road or stream? 6 When it rains or the ground is wet, do you experience problems with your drains? 7 When you do laundry, does a wet spot appear in your yard? 8 Do you frequently have to pump your septic tank (more than once a year)? 9 Is the grass over or around your septic tank greener than the rest of your lawn? 10 Is the area around your septic tank or drainfield wet or spongy even when it has not rained for a week or more?
What determines the depth below the soil surface that the bottom of the drainfield trenches can be placed?
Finally, the location of a seasonal high water table or a restrictive layer (such as hard pan or rock) determines the depth below the soil surface that the bottom of the drainfield trenches can be placed. The soil is the most important part of the septic system in treating and ultimately dispersing the treated sewage.
What is the purpose of a septic tank?
The main purpose of the septic tank is to stop solids from entering into the drainfield. If solids do reach the drainfield, they will clog the small spaces or pores in the gravel and soil below, resulting in sewage backing up into the house or surfacing in the yard.
How much soil is needed for a septic system?
The soil is the most important part of the septic system in treating and ultimately dispersi ng the treated sewage. If the soil beneath the drainfield is too wet, the sewage may not be adequately treated before it reaches groundwater. Furthermore, if a restrictive layer is too close to the trench bottom, the soil may not be able to absorb all of the sewage, thus forcing it to the surface or back up into the house. In North Carolina, there must be 12 to 18 inches of unsaturated soil beneath the drainfield trench bottom. This distance is referred to as the vertical separation distance. Environmental health specialists employed by the county or district health departments are trained to evaluate the soil and site to ensure that it is suitable for sewage treatment and dispersal. Additional information can be obtained in the NC State Extension publication Investigate before You Invest (AG-439-12).
What are the components of a septic system?
A septic system consists of four basic components: the source (home), the septic tank, the drainfield or leach field, and the soil beneath the drainfield (Hoover, 2004; Figure 1). Several different septic system designs are used in North Carolina.
What happens if water enters a septic tank?

What do you need to know about septic systems?
You must ensure that your septic system has a proper design and that an expert does the installation. It requires a good understanding of soil type and grading, among others. If, for example, the soil layer is too thin, it could result in a problem in the near future. You also need to ensure that you avoid too much moisture or saturation in soil. The expert will do a site check and advise you accordingly.
What type of soil is best for a septic system?
You may, for example, find that if you compact the soil too tightly, it may damage the pipes. The type of soil will determine how much weight it can take. Sandy soil for example is better than clay soil. Clay soil tends to waterlog, and the drain-field will be too wet, and the sewage will not undergo proper treatment before it reaches the groundwater. It is also essential that the experts take into account the water table, which will determine the positioning of the drain-field trenches.
What happens if your drain field is saturated?
The drain field may fail or become saturated with water, resulting in sewage backing up into the home. You may notice particular places in your yard that have healthy grass. You may also notice a bad smell near the drain-field or tank. This is a severe problem, which may damage your system irreparably. If the problem is too much saturation, a plumber can dry it out. Let the professionals handle this job because they will advise whether you need to change the whole system.
