Septic tank repair in Northern Ireland
Smells, slow drains or wet ground around your septic system? Find out what is wrong before deciding on repair or replacement. Contact us to discuss an assessment and the next steps.
A problem with the system does not always mean replacing the tank
Smells, slow drains and wet ground can have different causes. The assessment should consider the tank, connected pipework and drainage area before a repair or replacement is proposed.
Ask what the findings show, which part needs attention and why the proposed work is suitable. Repair options depend on the condition of your system.
- Connected pipework
Carries wastewater to and from the tank.
- The tank
The tank structure and internal components.
- Drainage area
Where discharge passes into the ground in a typical septic system.
Simplified system overview. Arrangements vary; an assessment identifies the parts involved.
Keep clear of an unsafe tank
Do not enter a septic tank or inspection chamber. Dangerous gases and lack of oxygen can be fatal. Keep people and pets away from sewage, open tanks and damaged covers; leave inspection and access to a competent contractor.
If someone is in immediate danger, call 999. Do not enter a tank to attempt a rescue. For an urgent water pollution incident, contact the NIEA Pollution Hotline on 0800 80 70 60.

01
Tell us what you have noticed
Call or request a callback. Your postcode, symptoms and any maintenance history help us understand the enquiry. You do not need to know the system type. Mention shared systems and access restrictions if relevant.
02
Agree the assessment and price
Discuss attendance, assessment scope and price with the independent contractor. Confirm whether emptying or specialist inspection is needed and who will arrange it.
03
Review the findings and proposed work
Ask which part has failed and what the options are. Agree repair or replacement costs, excavation, waste removal, reinstatement and any approvals before authorising work.
Check the consent and the proposed changes
Private sewage treatment systems in Northern Ireland require consent from the Northern Ireland Environment Agency. Have any existing consent, system plans and maintenance records available for the assessment.
Ask NIEA about the requirements for your system and proposed changes. Agree who is responsible for obtaining any necessary approvals; a repair quote is not a guarantee of regulatory compliance.
NIEA guidance on discharge consentsSeptic tank repair questions
Does a septic tank problem always mean replacement?
No. The condition and findings determine the options. Ask the contractor which part needs attention and why the proposed work is suitable. Not every system can be repaired.
How much does an assessment or repair cost?
Costs depend on the system, access and investigation required. Agree the assessment price before attendance and ask about separate charges for emptying, excavation, repairs and reinstatement.
Can you arrange routine tank emptying?
This page is for repair enquiries. Mention if emptying is what you need so the appropriate service can be discussed; it is not automatically included in an assessment or repair.
What if I do not know which system I have?
Say so when you contact us. Describe the symptoms and share any existing records. Do not open or enter the tank to identify it yourself.
Can I get a report for a possible insurance claim?
Mention the requirement before booking. Agree what the contractor’s assessment and report will cover and what it costs. PCLA can discuss the separate claims-support service; a report does not guarantee cover.
Who carries out and charges for the work?
You contract with and pay the independent contractor directly. NI Leak Detection arranges the introduction and receives no commission or financial reward for it.
