How a Septic Tank Works
Septic tanks are installed where there is no direct connection to sewer pipes. Learn how septic systems work
A septic tank is a form of On Site Sewage Facility (OSSF) to houses not connected to public sewer pipes. Septic devices act as domestic wastewater treatment in 25% of the properties in North America.
How Septic Tanks Work
The septic system is composed of a one thousand or two thousand gallons tank attached to a murky water pipe on one end and a drainfield on the other end. Waste is carried from the home to the septic tank where it is sorted into solids and liquids. Weighty solids plummet and produce a foundation sludge layer while unheavy solids go up and form an upper layer of scum. The anaerobic bacterial environment that develops in the watertight tank decomposes the two layers to liquid waste that is after that emitted to a drain-field, also known as a leachfield or a disposal field. The drainfield purifies liquid waste with a series of punctured pipelines running through subsurface trenches filled with gravel. As effluent drips from the pipes, through the gravel and saturates the soil - filtration occurs through which effluent is refined from harmful contents and is channeled to neighborhood water sources as drinkable water.
Symptoms of Septic Tank Failure
- Slow drainage of showers, tubs and sinks, as well as poor flushing toilets
- Repeated sewage backwashes
- Sewage odors
- Wastewater pooling close to the septic tank
Septic Tank Care
Frequent septic tank pump-out is vital for sludge and scum disposal. The regularity at which one should clean the septic tank depends on the original size of the tank. Periodic septic tank pump-out counteracts whichever of those complications already mentioned and extends the working cycle of the device. Septic tank cleaning is highly recommended to entrust with qualified plumbers with the befitting equipment to wash out tanks without harming the system or environment. Septic tank check-ups may go a long way at uncovering and fixing hidden faults before they impede the working order of the system.
