The History of the Septic Tank System

John Mouras is credited for inventing the septic tank system around the year 1860. The septic tank system is believed to have originated from the country of France where Mouras designed the septic tank and built a prototype made from concrete and also made the pipes leading from the tank out of clay. Pipes then lead from his house to the septic tank which was located in his back yard. 10 years later John Mouras decided to dismantle his tank and to his astonishment found that the tank was emptied of any solid waste and only contained a layer of scum. Mouras then submitted an application for a patent around 1881. The septic tank was then exported to the United States of America and later exported to Africa possibly by the British Navy.

A Standard septic tank is approximately 1000 to 2000 gallons depending on the size of the family who will be using it. The septic tank will have an inspection chamber with an inlet pipe were all waste water enters, which comes from the house and into the septic tank and an outlet pipe which will then go on for further treatment.

The septic tank will first separates the waste water into three layers, top layer is called the scum layer which consists of oil and grease which floats to the top, the second layer is called waste water which is basically water which will then exit through a T-shaped outlet pipe so it only release water into the drain field and the last layer is the sludge which is basically solids that have fallen to the bottom which will then be turned into sludge by some very helpful bacteria that helps break down the solid and turn into sludge.

What happens to the three different layers when they enter the tank?

The top layer called scum will need to be pumped out by a tank emptying company who will take the waste away. The second layer called waste water is exited through a T-shaped outlet pipe to a drain field which will then soak through the soil back to ground water and the third layer which is called sludge and eaten by helpful bacteria.

When the waste water (which is the second layer) passes through the outlet pipe it will then be returned to ground water through a system called a drain field. A drain field is usually made up of three or more perforated pipes that will be buried approximately 6? feet underground in which will typically have a layer of gravel around the pipes. A contractor will also check the soil for any substance that could make the waste water hard to absorb through the ground and back into ground water.

Here a bit of advice

Also aim to have your septic tank emptied at least every 2 years, but I would recommend having it emptied every year that way your tank should last you a long time.

Don?t flush too much harmful chemicals like bleach or disinfectants as this can kill the helpful bacteria within the tank that help break down the solids. Paper towels, sanitary napkins, nappies and hand wipes could clog up the system and your drain field. Liquids such as Motor oil, solvents, lubricants, petrol, paints, thinner agents and insect pesticides. Never use these items as they could pollute the drain field area and you could end up in trouble with your local council and fined and charged to clean the polluted area.
