If you live in a rural area, you probably need a
septic tank. However, the first question people often ask is ‘what size septic tank do I need?’. This article will look at what size septic tank is right for your home and how to calculate it correctly so that it works effectively for years to come.
What is a septic tank?
A septic tank is a container that moves and stores waste that comes from the drains in your home.
For people that live in rural areas, it’s common to have a
septic tank on your property since these houses don’t have access to the main sewage system.
It’s made of two parts – a
wastewater storage container and an underground drain field – that both help to separate waste that enters via your property.
What size water tank do I need?
A number of factors will determine the
size of the septic tank that you need, including:
• The number of people who live in your home
• How much waste a person produces
• The number of bedrooms
• The size of your property in square footage
To determine how much waste you accumulate, add up the number of people who live in your household and multiply it by the number of gallons of waste a person creates per day.
For a standard water system, a single person will create roughly 150L of waste daily. Therefore, if you’re a family of five, you would multiply 5 by 150 to estimate that you use 750L of waste per day.
Consider your house size
The bigger the size of your property, the bigger the
septic tank you will need. The Australian standards for
domestic wastewater treatment state that a septic tank must have a capacity of at least 2,400L. For a bigger house of 4-6 bedrooms, the tank must have a minimum of 4,500L capacity.
These guidelines are important because any calculation for the amount of waste that a house produces is just an average and often tells you the minimum size.
What happens if your septic tank is the wrong size?
If you have a
septic tank that is too small for your property, it can lead to a range of problems including blockages and overflowing.
Blockages can cause issues with the filters, resulting in the tank releasing liquid waste before it has been properly broken down or causing the tank to overflow and spill into your garden.
Similar problems may occur if your
septic tank is too big as without the right amount of wastewater flowing through it, it may not be able to form bacteria that assist in breaking down the waste in the tank.
Overall, it’s very important that you get a
septic tank that is the perfect size for your property to avoid any unnecessary maintenance issues.
