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.

How Much Does A Septic Tank Hold?

If you’re thinking about installing a septic tank system in your home, the type as well as the size of the tank are the most common things to put into consideration before making a decision. Private sewage disposal is very common in the rural areas which are unable to access the mains sewage system. Septic tank systems that includes a soil absorption system or a drain field is the most affordable way that you can treat your household’s waste water. To get the size of your septic tank, you’ll have to determine the size of the house as well as the number of people living in it.

Septic tanks have three common types that are used in domestic construction. These includes:

✓ Concrete septic tanks

✓ Polyethylene or plastic septic tanks

✓ Fibreglass septic tanks

The most common type of septic tanks is the concrete tanks, however, they’re usually very heavy and would require a machinery to install. Plastic and fibreglass septic tanks, on the other hand, are much lighter which makes them more ideal for remote and hard to reach places.

Several influencing factors can play a key role in determining the size of the septic tank you need. These includes the home’s square footage, the number of bedrooms as well as the number of people that resides in the house. Below are rough estimates of septic tank sizes you’ll need depending on the square footage and number of bedroom.

✓ One and two bedroom homes of less than 1500 square feet will require a 750 gallon septic tank.

✓ Three bedroom homes of less than 2500 square feet will require a 1000 gallon septic tank.

✓ Four bedroom homes of less than 3500 square feet will require a 1250 gallon septic tank.

How To Install A Septic Tank

If you’re planning to get a new septic tank system or replace the existing one, you’d probably want to know if it’s a task you can do all by yourself especially if you happen to be a competent DIYer. However, unless you’re a heavy equipment operator, installation of a septic tank system is by no means a DIY project. And even if you have the heavy machine at your disposal and you know quite well how to use it, you’re still going to need the guidance of professionals.

You’re going to need the services of a soil expert to evaluate the site, a plumbing contractor to fit and connect pipes, an engineer to design a good system and more. You may want to be involved in all these but local health authorities requires that a licensed personnel should be in charge. In this article, however, you’ll discover the septic tank system installation process.

To install a traditional septic tank system, you’ll have to start by digging a hole for the tank following strictly the instructions provided on your approved plan by the local authorities. Do not drop the tank into the hole after digging, you’ll need to connect it to the building sewer with 3 or 4 inch waste pipe which should be at a minimum slope towards the tank. Then, extend a drain pipe from the other end of a tank to a the distribution box on the drain field.

Once completed, dig several parallel trenches of this box extension across the drain field. Put in a layer of gravel along with 3 to 4 inch perforated pipes in individual trench and connect the pipes with the distribution box and cover them once done.

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.
