  • Our experienced and friendly drivers take pride in completing the job safely and without disruption to your property, garden and surroundings.
  • Once we’ve emptied your septic tank, cesspit or sewage treatment plant, we transport the waste to a licensed treatment facility. Our team of sewage experts are always working on innovative solutions, which keep the environment in mind.
  • We’re fully licensed by the Environment Agency and British Water members to give you complete peace of mind and help you rest assured our standard of service is one of the best in the industry.
  • For every household which has at least one empty with us in a year, we’ll donate 50p to Toilet Twinning, a global charity supporting the development of sanitation in the world’s poorest countries. Last year we donated £11,000! Find out more about our partnership with Toilet Twinning.

The Environment Agency (EA) rules state that you must arrange a septic tank or cesspit emptying once a year or in line with the manufacturer’s instructions. The septic tank or cesspit might need to be emptied more frequently if smaller or depending on the number of people living at your property. Our operators are happy to advise on how frequently your sewage system needs to be emptied on the first visit

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.
