Frequently Asked Questions
A Septic Tank is a domestic scale version of a sewage treatment plant. The treated effluent drains from the tank’s outlet pipe to a suitable size percolation area to a soak away naturally into the ground. During the treatment process waste material settles in the tank and is digested by natural bacteria. Over time partially-decomposed solids build up on the bottom of the tank. This sludge needs to be removed regularly to make sure the tank continues to function properly and to prevent the soak away becoming blocked. Click on the questions below for more information.
