Septic Tank Desludge Request
Please note you will be charged for this septic tank desludging request.
All domestic customers are entitled to one free request a year. Please contact our Contact Centre on 0345 8770030 if you wish to discuss further.
We aim to complete all standard requests within 12 working days, and all urgent requests within 3 working days. Do you wish to continue?
Northern Ireland Water would also like to advise you of the following:
- We aim to carry out the service within 12 working days.
- The service we provide is the removal of up to 4.5m3 (990 gallons) of sludge from the base of the tank, NOT a full empty. In older tanks, it is important that the scum layer is not disturbed and that some sludge remains so that the waste treatment process can continue. The level of liquid waste in the tank will largely remain unchanged.
- Should you continue with the request a docket will be left, confirming that the service has been completed.
NI Water would remind customers that children and animals should be kept well away from the septic tank before, during and after the desludging process.
