Who are SepticTankRepairsNI? 

We are a team of Civil Engineering professionals who specialise is installations and repairs of ‘off-mains’ drainage systems. If your domestic drainage system is not connected to the public drainage network your system is termed as ‘off-mains’. Your domestic sewage will be collected and treated in a Septic Tank (ST) or a Sewage Treatment Plant (STP). 

Owning a Septic Tank or Sewage Treatment Plant

Your Septic Tank is designed to discharge effluent into the sub-soil via perforated pipes (a drainage field). A sludge is left behind in the tank. The sludge within your tank should be sucked out at least once a year, and in some cases more often. You are entitled to one free de-sludging per year which is provided by NI Water.

Has your Septic Tank been reported as damaged on your annual Desludging Notice?

Did you know – NI Water, or their agents, are now informing homeowners if their septic tank is damaged.   If your NI Water tanker driver has recorded damage to your septic tank on your Desludging Notice, you may be entitled to a full repair of your tank through your household building insurance. **
