How Your Septic Tank Works

Welcome to UKDP today we will explain how your septic tank works After the foul waste or effluent flows via the drain pipes from your property, it makes its way to the septic tank possibly through several inspection chambers or manholes

And ultimately discharge to the drainage field The septic tank is generally located within the boundaries of your property, and can usually be identified above ground by two or three manhole covers situated relatively close to one another Lets have a closer look at the septic tank A standard septic tank is divided into two chambers Each chamber is equipped with an inlet and an outlet pipe

Known as a "T-Piece" or a "Dip Pipe" by their distinct shape Once the fluid reaches the level of the outlet pipe, in the first chamber it will overflow into the second chamber When the foul waste water settles in the first chamber, the solids in the water breakdown and separate into three distinct zones or layers The top layer is made up of fat and solids that have not yet broken down This is also known as the crust

The second layer is mostly dirty water and commonly known as liquor The bottom layer is known as sludge and consists largely of more dense waste that builds up slowly over time The top and bottom layers must be removed when the tanker comes to desludge the tank The inlet and outlet dip pipes play a vital role in retaining the solids in the effluent, long enough that they can be broken down As the chamber fills up, the vertical section of the dip pipe prevents fat and floating solids and liquid from making their way into the next chamber

The separation process will repeat itself depending on how many chambers your septic tank has The liquid discharge from the tank makes its way to the drainage field situated after the septic tank If you are experiencing any problems with your properties drainage system, call UKDP on 01628 788 600 or email at: info@ukdpsolutionscouk
