The most common domestic sewage treatment system used in rural areas is the septic tank-soil absorption program. Chemical Contamination - Moderate use of home drain solvents, cleaners, disinfectants, etc should not get in the way with the operation of the septic tank program, however indiscriminate use may possibly cause problems. The sludge in the septic tank - inorganic and inert material - is certainly not biodegradable and will certainly not decompose. If not taken out, the sludge will collect until it eventually overflows, again clogging the soil absorption area.
A solid waste tank is the initial and first treatment component in a septic system. When ever water flushes down the drain, it connects for the main sewer pipe leading from your house to your septic tank. Once the water enters the tank it becomes sewage. This wastewater settles as well as the solids separate from the liquids and form layers inside the tank. If there is no tank or tanker available, the pumped-out material must be disposed of in a hole near the septic tank.
The solid waste tank, Mr. Keeton stated, will be built out of either concrete, stainlesss steel or fiberglass and it is generally a rectangular box that may hold 1, 000 to 1, 500 gallons of spend. The tank is usually buried a few feet strona autora below the surface and has a covered starting through which it can easily be cleaned. One end of the tank is usually connected to the primary sewage line coming away of the house and the other end is connected to the distribution box.
Your solid waste system treats tonnes of organic waste each time of year. The tank treats manure by letting the heavy solid materials settle and allowing time for lighter "scum" to float for the top. This partly cared for liquid then flows in perforated pipes, called the leaching bed, where this filters into the surface and is also further treated. Beneficial bacteria and other ground organisms the actual bulk of the work.
Leakages out of the solid waste tank: As we explained above, a low level of sewage in a septic tank that has recently been in active use means there is a container leak out. In a home occupied by a family of four persons, an empty 1000 gallon septic tank (having just been pumped) would be expected to be full of liquid waste and sewage again in about a week or even less.
