We offer a range of septic tank de-sludging services to customers who own a private septic tank which takes standard waste, such as sewage and waste water, where suitable tanker access is provided.

If you meet all of our basic conditions the standard charges shown below will apply. If you do not meet all of our basic conditions we may still be able to de-sludge your tank, but not at the standard rates shown below. For details of our basic conditions or any further information about septic tanks please call us on 0800 0778 778.  

Criteria includes: 

  • weight and manageability of the lid of your tank (i.e. capable of being moved or lifted by one person).  
  • position of your tank (i.e. accessibility and/or distance and height from the tanker). 
  • vehicle access and parking facilities.  

Please note this is not an exhaustive list and other factors may apply. 

Customers are reminded that Scottish Water reserves the right to refuse the de-sludging of a septic tank if the conditions are not met and the situation is considered unsafe.  

Furthermore if lids are not readily accessible, not free from any apparent damage; or not seized or locked in position we will not be liable for any damage caused.   

All charges below are based on one tank being de-sludged. If you need multiple tanks on your property de-sludged at the same time we will provide an estimate prior to any service being delivered.
