From tanks, pits and lagoons through to interceptors, sumps and processing areas, our teams help businesses safely remove difficult waste materials, maintaining compliant treatment and documentation throughout the process.

From pumpable sludges to thick, compacted material that’s hard to remove, we have an extensive fleet of specialist vehicles equipped to handle challenging sludge removal and difficult-to-access environments.

How Does Our Sludge Removal Service Work?

Tell us about your sludge source, estimated volume, storage arrangements and site access. Let us know whether the material is pumpable, settled or heavily compacted, and share any available waste analysis.

We assess the waste and site conditions before agreeing the removal method, equipment, timing and treatment route. Depending on the project, this may involve specialist vacuum tankers, pumps, jetting or agitation to help mobilise settled material. Sonar surveys and dredging equipment may be appropriate for larger tanks or lagoons.

Where suitable, centrifuge dewatering can separate liquid from solids and reduce the water content of the sludge. The separated materials still require assessment and suitable handling.

Our team removes the waste, arranges transport to an authorised receiving facility and provides the relevant waste documentation.

Frequently Asked Questions About Industrial Sludge Removal

Do you remove both silt and sludge?

Yes. Subject to assessment and acceptance, we can support the removal of both sludge and silt waste streams from a wide range of commercial and industrial environments.

Yes, subject to assessment. Specialist vacuum tankers and removal equipment can be used for suitable thick or settled sludges. We may need to agitate or mobilise the material before extraction. Dewatering is a separate process used to reduce the sludge’s water content where appropriate. Our team will confirm a suitable method based on the waste characteristics and site conditions.

We regularly support sludge removal works in restricted-access and operationally challenging environments. As a first step, we’ll assess your site’s access requirements to determine the best equipment and approach.

Where practicable, we use suitable equipment to remove sludge without entering the tank, chamber or other confined space. The method depends on the waste conditions and site assessment. If entry is unavoidable, it must be planned under a safe system of work, with appropriately trained personnel and suitable emergency arrangements.

To help us provide an accurate quotation, we’ll usually need:

  • Estimated sludge volumes
  • The type of sludge if known
  • Site location and access details
  • Tank, pit or lagoon dimensions where relevant
  • Whether the sludge is pumpable or heavily compacted
  • Any contamination or hazardous characteristics
  • Site operating hours or restrictions

If you’re not sure on any of the above, reach out to our team and we can point you in the right direction and answer any queries.

Yes. Where required, we can use jetting, cleaning and waste mobilisation to improve access and removal efficiency. 

Minimum charges may apply. Due to the high levels of technology and processes involved, this service is designed primarily for industrial and commercial waste producers, rather than domestic septic waste removal.

Yes. We can arrange waste sampling and classification support where required to help confirm the waste profile, support compliant routing and provide accurate pricing.

Once we’ve removed the sludge from your site, we transport it to a licensed treatment, recovery or disposal facility (depending on its composition). We aim to treat and recover waste wherever possible.

Sludge can be hazardous or non-hazardous, depending on the process that produced it and the substances it contains. Its appearance or thickness does not determine its classification. Share any available waste analysis with CSG so the appropriate waste code, handling requirements and receiving facility can be assessed.

No. Dewatering separates liquid from solids, but it does not automatically remove all contaminants or make the water suitable for discharge. The separated liquid and solids still need assessment. Any discharge must meet the applicable requirements, including any necessary sewerage undertaker consent or environmental authorisation
