How Septic Tanks Work

If you’ve never lived in a home with a septic tank, or have just never come across one before, then the terms “septic tank, septic system or cesspit” may confuse you. Regardless of how septic tanks have become relevant in your life, you’ve landed on this article for one reason, you’re trying to find out what septic tanks are and if they’re important. As leading experts in the industry, D.C. Merrett will provide an informed view on the matter & will have the discussion of whether or not septic tanks are important & why they might or might not matter.

Put very simply, septic tanks are large tanks that are plumbed up to a property that collects the waste water from all connected drains & toilets. The tank itself is split up into two chambers (generally). The treatment chamber is the first “filter” the wastewater goes through as it treats the sewage before it’s discharged. The liquid waste is vented into something called a “drain field” or “leach field”. Drain fields are used to discharge waste liquids from the tank, allowing for more waste to be stored. If a septic tank didn’t discharge the liquid waste, the tank would fill up in no time at all.

The drain field is usually located in an open space beneath the top surface, allowing for the liquid waste to be absorbed into the surrounding dirt & soil. An appropriate location will have to be designed for your drain field if you’re having a septic tank installed into your home. For those that are worried about dirty liquid waste spoiling their land, special measures are taken to ensure that no foul smells or waste ends up on top of your land. With most septic tank installations, Gravel is placed around the drain field pipes which allow the water to flow into the soil. The mix of water, gravel & oxygen allows the bacteria in the gravel and the soil decompose the waste that’s in the water.

If septic tanks fill up over time, do they need to be emptied?

Septic tanks do release liquid waste ensuring that it doesn’t fill up too quickly. This does mean, however, that solid waste that is kept in the tank will eventually fill up. Special bacteria & treatments are added & carried out to your septic tank which allows the solid waste to be decomposed/eaten so that you’ll get a longer life out of your septic tank before you have to have it emptied. It is a good idea however to have your septic tank emptied regularly to ensure that you aren’t experiencing any issues with your tank.
