A Fosse Septique is an underground sedimentation tank, which is known to treat wastewater by biological breakdown and drainage. A septic tank helps in the treatment of the wastewater from different household areas using natural processes and proven technology. The design of a sewage plant system is quite basic.
Complete working of fosse septique
There are two pipes called inlet and outlet that is connected to the fosse septique. The input pipe collects greywater from the residence and transports it to the septic tank. It is held here for long enough for the solid or liquid waste to be separated.
The exit pipe is the second pipe called drained pipe. This pipe transports pre-treated effluent from the Fosse Septique then distributes it evenly throughout the soil and waterways.
After some time has passed, wastewater will begin to separate into three layers.
- Oils and grease make up the top layer, which floats above all other waste. This is frequently known as “scum.”
- Wastewater and waste particles are contained in the middle layer.
- The bottom layer is made up of atoms that are lighter than water and form a sludge layer.
Bacteria in the tank work their best to break down the solid waste, allowing liquids to readily separate and drain away. What’s left at the bottom of the vessel needs to be removed regularly as part of routine maintenance. One of the reasons a septic system is only a basic method of sewage treatment is because of this.
Working Of septic tank
- Water from your cooking area, bathroom, and other drains fixtures into a one main drainage pipe, which will lead to the septic tank.
- The Fosse Septique begins the process of storing wastewater underground. It must hold this for long enough for the solids to sink to the bottom and the oil and grease to float to the top.
- The liquid sewage sludge (effluent) will be able to cancel this same tank and into the sewer system after this process.
- The wastewater is discharged into porous surfaces via pipes. These allow effluent to pass through the soil and filter.
- As wastewater percolates through to the soil, it is accepted, treated, and dispersed, eventually discharging to groundwater.
- Finally, effluent percolates into the soil, removing harmful Escherichia coli, viruses, and other pathogens naturally.
How does a septic tank work?
Fosse Septique systems in the form of simplified onsite sewage facilities (OSSF) that merely treat the waste. Septic tanks are used to safely dispose of wastewater in residences with poor drainage or those that are not linked to the public sewage system.
They collect excreta and effluent in a single large underground tank and are primarily utilized in rural areas.
Septic tanks are typically constructed underground half a mile from the residence. They normally have two chambers or compartments, as well as a tank that accepts wastewater from an entrance pipe.
Storage systems are not required for those who reside in cities or towns because effluent will be carried and dealt with by their sewage system. A local water corporation will look after and administer the system.
So, now that you understand the entire operating technique of the fosse safetique, you may be aware of the significance of the safety containers and can respond accordingly without hesitation.
