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.

Booked CSG to empty our septic tank. We've never done this before and they were extremely professional with great... customer service. They called when I made the booking to let me know they were processing it, then called again to check access as we have a narrow driveway. The engineer turned up first thing on the day alloted and was friendly, polite and efficient. Great more

As always a pleasurable experience from a company carrying out a tricky job. It is very nice to see the same chap who... knows our waste water system, it also says much for the company that it is the same man. All the work carried out cleanly and efficiently. Happy to more

Used for domestic waste tank emptying. Booked on-line received a call the same day to confirm the booking. The team at... CSG stayed in touch throughout to make sure we'd be in. Turned up in a clean well maintained vehicle with a professional driver who then proceeded to get straight to work. Sceptic tank emptying can be a real mine field of people not turning up, tank not being fully emptied etc. CSG are the solution to this, book and pay on-line, they call you, appointment booked, tank emptied, reports and receipts e-mailed to you all at no more cost than any of the other companies. I won't use anyone else now and can happily recommend them to more
