how does a septic tank work?

How Does A Septic Tank Work?

A septic tank system is an alternative to the mains sewage system whereby the wastewater is treated underground and is able to last for many generations. They’re mostly found in rural setting where there’s a lack of centralized sewer systems due to the difficulty in installing and managing them. These type of systems make use of the perfect blend of natural resources and advanced technology to treat wastewater produced from household plumbing. These includes the kitchen drain, bathroom, laundry room and more which all runs to the septic tank. When it gets to the septic tank, the organic matter will be digested and floatable matter alongside the solids are separated.

In this article, we’re going to give you a better understanding of how a modern septic tank works. Let’s take a look!

✓ All water stemming from your household goes straight into the main drainage pipe that lead directly to the septic tank.

✓ Meanwhile, the septic tank, which is usually underground and happens to be a water tight container, retains the waste water for a period long enough to enable the solid materials sit at bottom and start to dissolve. In the process, both oil and grease will float to the top as a layer of scum.

✓ Any wastewater that’s liquid will then leaves through the drainfield out of the septic tank.

✓ The drainfield, on the other hand, is a shallow excavation that’s made of unsaturated soil. The treated water is transported via the piping onto a porous surface which enable the filtration of the wastewater into the surrounding soil. The soil, in turn, treats and disperses the wastewater.

✓ Finally, the wastewater percolates into the soil for the removal of harmful bacteria alongside other contaminants.

do septic tanks smell?

Do Septic Tanks Smell?

The simple and shot answer to this question is yes, septic tanks smell. There are a plethora of very pleasant fragrant smells to enjoy in the United Kingdom, but the smell that oozes out of septic tank systems are certainly not one of them. In fact, if you care for yourself a lot, you should not even try smelling your septic tank at all. However, if you do notice a bad odour wafting from the direction of your tank, it may be that there’s an indication that something is not right. The septic tank system is always with strong malodorous scents, but when you start smelling the odour from the septic tank on your property, then something is wrong and if ignored, may lead to a contamination of your water supply and or other dangerous situations.

✓ When you’re able to perceive the smell of your septic tank from your property, it may imply a full or overflowing septic tank. In this case, you should call in a professional to have your tank pumped. Generally, most tanks are designed to be pumped every 4 years but this is definitely going to vary depending on the size of of the tank as well as your home’s water usage.

✓ Another possible reason for a smelly tank is a covered septic tank vent. This usually happens when a home is renovated or remodelled after the septic tank system has been fitted. You should make sure that the septic tank vents are always uncovered.

✓ If the septic tank starts to get smelly right after showering, then it’s most likely that the septic tank was not installed the way it’s supposed to and may have been fitted without any type of vent.

✓ A smelly tank can also be caused by inappropriate items making their way into a system like cooking grease, oil or fat, paints, solvents, industrial cleaning products, condoms, feminine hygiene products and so on.
