It's hard to imagine living in a farmhouse without the benefits of civilization, such as a bathroom, shower and toilet. So, the main issue for individual building owners according to Mike Clark Excavating & Septic Pumping is to remove and dispose of wastewater without harming the environment. And if earlier, in most cases, gypsum or sewer wells were equipped to remove sewage, today, any country building is improved, summer homes in the absence of a central sewer system are constructed by introducing home or installation autonomous sewage treatment systems, the main element of which is septic pit. Consider what a septic tank is, its structure and the principle of operation of a local cleaning system or, in other words, study how a septic tank works.
Two-chamber septic tank
The septic tank is a major element of the autonomous cleaning (sewerage) system of civil engineering of individual buildings, which is designed to collect and clean household, sewer and sewage systems. Installation of a septic tank for sewage is carried out in case of absence or inability to connect to the central cleaning system. Local sewage systems have affordable cost, compact sizes, high operational and quality parameters. An autonomous treatment plant consists of a tank, which can be concrete, metal or plastic (polypropylene). In addition, each material has its advantages and disadvantages.
Plastic septic tank
Plastic containers are lightweight, easy to install, and are not subject to corrosion, but due to their low mass in case of improper installation, they can be pushed to the surface by groundwater. The process of installing reinforced concrete septic tanks is more complex, time consuming, but at the same time, this design has greater reliability, is not under groundwater pressure, can withstand significant loads and is not subject to corrosive processes. Septic tanks made of metal stronger plastic structures, but are susceptible to corrosion.
Septic tanks have a different volume and, depending on the model, can be:
single beds; two-chamber; three-chamber.When selecting a septic tank, the number of permanently living people, the principle of operation of the local treatment system, the depth of groundwater location, the special terrain topography, the qualitative characteristics of the soil and the design of a particular treatment model should be taken into account.
When choosing a septic tank, you must also consider the daily amount of wastewater:
If the daily discharge volume is less than 1 m3 - The capacity of one bottomless chamber is sufficient. If volume exceeds 1 m3 / day - establish a double or three-chamber septic tank.
The septic tank cleans the water well
The main advantages of using septic tanks are:
Effective and rapid treatment of pollution wastewater. Even the simplest septic tank cleans drains by 70-80%; possibility of installation in any climatic and weather conditions; ease of installation and maintenance.
Having experience and skills in performing construction work, you can install the local sewer system yourself; no need for frequent pumping; long service life, but only with proper installation and operation; Some septic tank models are independent of the power supply system.
