Keeping Your Off-Mains Drainage System Compliant, Efficient and Environmentally Friendly.
If you own a modern sewage treatment plant, you know it’s a sophisticated piece of kit. Unlike a traditional septic tank, these systems use mechanical components and aerobic bacteria to treat wastewater to a high standard. To keep those bacteria healthy and the mechanical parts moving, regular treatment plant emptying is essential.
At Canford Tankers, we provide expert desludging and emptying services for all major brands, including Klargester, Conder and Tricel, across the whole of Dorset and Hampshire.
Why Regular Treatment Plant Emptying is Critical
A treatment plant works by circulating air to encourage bacteria to break down waste. Over time, a “sludge” layer of non-organic solids builds up in the primary chamber. If this isn’t removed:
- Mechanical Failure: Excess sludge can clog air diffusers or damage the internal motor and pumps.
- Environmental Pollution: If the sludge level gets too high, it can wash out into your drainage field or watercourse, leading to heavy fines from the Environment Agency.
- System Death: If the sludge smothers the “good” bacteria, your plant stops treating waste and starts acting like a very expensive, very smelly bucket.
Our Recommendation: To stay compliant with the 2026 General Binding Rules, most manufacturers and environmental guidelines require treatment plant emptying at least once every 12 months.
Signs Your Treatment Plant Needs Emptying
- The “Rotten Egg” Smell: A healthy plant should have an “earthy” aroma. A strong sulphur smell usually means the air isn’t circulating because the tank is too full.
- Visual Warning Lights: Many modern plants have a control panel. If your red alarm light is on, it’s time to call us.
- Cloudy Discharge: If the water leaving the plant into the ditch or stream looks murky or contains solids, your primary chamber is overdue for a pump-out.

What our customers say.
Delighted with the service my parents have received. Craig was very professional and courteous, with excellent communication skills. Thank you
Terrific job done renewing our main sewer drain and replacing two manholes. A really professional service performed from start to finish. Thanks to Darrell, Jay and his son Charles, and Ben the engineer.
Absolutely amazing service for my dad. Craig (I think that was his name) was so kind and friendly and sorted the blocked drains despite restricted access, dreadful weather and all kinds of tree roots blocking the drain. I don’t think the drains had been seen to for about a hundred years. Exceptional service, attended in less than an hour and was so sweet to my auntie and dad. One million percent recommended. Thank you
Thank you for such professional service yesterday from beginning to end. Calm and helpful telephonist followed by our engineer, Darren, who resolved our issue in the awful weather conditions. A great company to work with.
I have used Canford Drains several times over the years due to tree root problems in drains. I have always found them to be very professional and their staff very friendly and helpful. I would highly recommend them.
Excellent service! I called the number and within the hour, Gerry had turned up on my doorstep. He was very knowledgable, professional and efficient. He sorted the problem and found another one fixed that quickly too! Would highly recommend.
Very Professional Drainage Company, Highly recommended. Beware of unreliable competitors.
Someone came out the following day and couldn’t have been more helpful. They explained what they were doing and what the problem was. Excellent service, would recommend.
