What Can Go Wrong If Your Sewage System Isn’t Frequently Emptied

  • Your sewage tank may leak, and an abundance of water around the drainage field of your septic tank might appear.
  • Sinks in your house could drain slowly and toilets take longer to flush, even when you have tried to unclog the drains.
  • A foul and nasty smell could arise in the area of your septic tank, cesspit or sewage treatment plant.
  • Grass, plants and flowers might start growing faster in the area around your septic tank or cesspit, compared to other parts of the garden.
  • If you sewage discharges into a watercourse, there may be overflowing sludge or scum on the water.
  • Solids could enter the soakaway, leading to soakaway damage.

British Water and the Environment Agency recommends that you empty your tank annually, and by doing so you will avoid expensive repairs to rectify the points above. However, if any issues arise, CSG is here to help you with the maintenance and repair of your sewage tank.
