If your home isn’t connected to a mains sewage system, chances are you’ll need a septic tank. These systems quietly do the dirty work, treating and disposing of your wastewater on-site. But if you’re wondering what is a septic tank, how does a septic tank work, or you’re considering a septic tank install, this guide breaks it all down in simple terms.
Let’s walk through everything you need to know — from understanding how a septic tank functions to what’s involved in a septic tank installation.
What Is a Septic Tank?
A septic tank is an underground wastewater treatment system commonly used in rural areas without access to the public sewage network. It safely processes household waste from toilets, baths, sinks, washing machines and dishwashers.
When wastewater leaves your home, it travels through a main drainage pipe into the septic tank, where the magic begins.
How Does a Septic Tank Work?
The way a septic tank works is actually quite simple but very clever.
Wastewater flows in: Everything flushed or drained in your home enters the septic tank.
Separation happens: The tank holds the wastewater long enough for solids (called sludge) to sink to the bottom and oils and grease (called scum) to float to the top.
Natural treatment begins: The liquid waste in the middle (called effluent) exits the tank and is distributed to a drainage field (also called a soakaway), where it’s naturally filtered by the soil.
Bacteria do the work: Good bacteria in the tank break down the solids, helping reduce the amount of waste and keeping the system balanced.
It’s a quiet, underground system that, when working properly, you barely notice. But it needs regular maintenance and the right installation to keep things running smoothly.
Signs You Might Need a New Septic Tank
Not sure if you need a septic tank install? Here are a few signs:
You’re building or renovating a rural home
Your current septic system frequently backs up or smells
You notice soggy spots or standing water near your drain field
Your tank hasn’t been inspected or serviced in years
Septic Tank Installation
Installing a septic tank isn’t a quick DIY job. It requires careful planning, the right location, and professional skills. Here’s what a septic tank installation generally involves:
1. Site Survey and Permits
Before digging anything, a professional will inspect your property to assess soil type, drainage capability, and the best place to install the tank. Depending on your location, you may also need planning permission or to meet specific environmental regulations.
2. Choosing the Right Tank
Septic tanks come in different sizes and materials (concrete, plastic, fiberglass). The right one for your home depends on the size of your property, the number of people in your household, and your wastewater output.
3. Excavation and Placement
The tank is installed underground in a spot that allows for safe and efficient drainage. This step involves excavation machinery and expert handling to avoid damaging pipes, cables, or surrounding areas.
4. Connecting the System
Your household’s plumbing is connected to the tank, and the tank is then connected to the soakaway or drainage field.
5. Inspection and Testing
Once installed, the system is tested to ensure everything works as it should and complies with local regulations.
