Septic Tank De-sludging Charges 2023 - 2024
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.
- 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.
- tank is in good working order and is free of damage.
Please note this is not an exhaustive list and other factors may apply.
For further details of our basic conditions or any further information about septic tanks please call our Customer Helpline on 0800 0778778.
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.
