What is a septic tank?

A septic tank collects and treats water from a household that isn’t connected to a mains sewer system.

Stored underground a septic tank uses natural processes to treat waste water/sewage that it stores and is usually made up of two chambers.

How it works

Waste water collects in the first chamber and naturally separates over time with solid sinking to the bottom and oils/grease forming a layer of scum across the top. Leaving in the centre a relatively clean section of water which is then released into a septic drainage field, otherwise known as a seepage field.

The layer of scum over time should naturally dissolve with the bacteria that is present and the remaining waste should be professionally removed periodically – this process is called desludging.

You must be very careful not you dispose of any items such as: food waste, nappies, plastic bags or wet wipes via sink or toilet as this could cause the inlet pipe in your tank to block causing you all sorts of nasty issues!

You must take care of your seepage field also. Try to avoid planting any trees or plants in the field as the roots may become damaged or cause damage to the inlet and seepage pipes. Try not to put any concrete over it and try not to drive over it as, understandably it could be very soggy!
