Septic tanks treat waste water from properties that are not connected to the public waste water system.
A septic tank is usually either a large rectangular box made of brick, stone or concrete, or a bottle-shaped plastic tank buried underground not far from the property it serves.

How does a septic tank work?
A septic tank works like a simple waste water treatment works and the treated waste water drains from the septic tank's outlet pipe to a soakaway or stream. Waste material (sludge) is allowed to settle in the tank and is digested by natural bacteria breeding in the tank. Over time the sludge builds up on the bottom of the tank. This sludge has to be removed regularly to ensure that the tank continues to work properly and to prevent the soakaway becoming choked.
How often should a septic tank be de-sludged?
This is dependent on the tank size and how well it is working. If you know where the septic tank outlet drains to, check that the discharge is a light grey colour. If the liquid includes dark solid material or recognisable sewage solids, this shows that the septic tank needs de-sludging.
If you dispose of certain substances and materials down the toilet, or down sinks, you risk either blocking a drain or upsetting the natural processes within your septic tank. This will stop it working properly and could lead to serious problems of pollution or choking of the soakaway disposal system.
Septic tank do's and dont's
- flush only human waste and toilet paper down the toilet
- use cleaning/washing products in moderation without upsetting the natural balance of the septic tank
- use bleach and disinfectants sparingly as they can kill good bacteria in the septic tank
- flush anything other than human waste and toilet paper down the toilet
- pour oil, fat or grease into drains leading to the septic tank
- connect rainwater drainage pipes to the septic tank
- dispose of waste liquids that are harmful to septic tanks into rainwater drains
- enter a septic tank; dangerous gases are produced by the natural treatment process
