Any septic system consists of several porous tanks and a number of pipes. It is designed in such a way that excess amount of water is carried away either to drainage system or in the field. The water that is carried out contains different types of chemicals like nitrogen and phosphorous materials and also different kinds of bacteria that can become a fertilizer. The excess water that enters in the field will get eliminated due to various natural processes which also includes percolation into the soil, evaporation, going into plant’s root or going into surface or ground water. As the new waste water moves into septic tank, the original water gets displaced.
Whether the septic field design has been engineered or any standard design, problems in septic tanks do crop up as the system becomes older. Sometimes there can be breakdown of generation of organic material due to bacteria and it causes the formation of gas. There must be provision in the piping system so that the gases may not get transferred in the house and cause diseases in the household.
There can be a number of reasons that can cause septic problems. As a homeowner, you must be aware about them and take necessary corrective action so that it can be resolved before it becomes totally out of control.
Following are few most common problems of septic system in residential as well as commercial properties.
- Sludge buildup
If the septic tank is not periodically emptied then after a long time there can be massive sludge built-up which is a problem. If the pumping out of the tank is not working then such solid waste gets settled at the bottom of the tank. If the sludge also flows along with the liquid into the drain then it can clog the drainage system too. Therefore, you need to regularly pump out your septic tank. The usual frequency of cleaning the tank can be anything between one to two years.
- Sodium binding
In some of the septic system there is too much salt going into the drain. Salt usually remains suspended and can exit into the field or drain. It can harden the pipes and it becomes impermeable. In that case, you need to dig up and reset the piping.
- Grease buildup
Usually from kitchen due to use of oil, it may cause grease build up in the safety tank and it can often clog the pipeline. You need to overload the septic system with water to prevent the clog formation within the pipe.
