A septic tank which is not working as it should can pose a serious biohazard to your property with sewage potentially becoming blocked in your drains or the sewage bubbling up to the ground outside your property.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Toilets and washing machines will begin to work inefficiently, becoming slow and unable to operate as they should. If a toilet cannot successfully complete a flush cycle, it is advised to check the septic tank for problems.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Liquids will travel to the drainage pit, but any heavier substances will sink to the base of the tank and remain there as sludge. Eventually, the sludge will need emptying from the tank as it will reach a point where it will begin to create a blockage. This will become evident when the toilets and drains within the property show signs of slowing down.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

The odour caused by this spillage will be evident, at which point it will require professional intervention. In order to prevent any serious damage to the property and the septic tank it is advisable to call in a professional off-mains drainage specialist. In this instance they will undertake an assessment to determine what repairs are needed and whether a new tank is required.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Septic tanks tend to be installed at properties that are not connected to the public sewer network. They are typically fabricated from often made of concrete, fiberglass or plastic and installed below ground and are used to collect and then to naturally treat sewage (a mixture of waste water and excrement) so that it can be drained to surrounding environment.&lt;br /&gt;
&lt;br /&gt;
They generally consist of two chambers. Waste water and excrement enters the first chamber via a drain. The solids slowly settle to the bottom, and grease and oil remains at the top, and are slowly broken down by bacteria. This leaves a layer of clarified water in the middle that is drained to a second chamber and then out to sub-soil in a septic drain field (also referred to as seepage field or leach field) which disperses the discharge to ensure it does not cause pollution. Drain fields should remain free of trees or hard landscaping and should not be used by traffic.&lt;br /&gt;
&lt;br /&gt;
Material that remains in the tank will need to be removed occasionally by a professional disposal company (de-sludging) to prevent a build up of material overflowing into the drain field.&lt;br /&gt;
&lt;br /&gt;
The most common problem associated with septic tanks is blockages. This may be apparent by poor drainage in the property, smells, backing up at manholes and so on. Items such as food waste, nappies, sanitary towels, tampons, cotton buds, wet wipes and so on may cause blockages to form or may hinder bacterial action and so should not be flushed or drained into septic tanks.
