Environmental guidance for your business in Northern Ireland & Scotland
An individual septic tank serving a household, if it is properly maintained doesn’t pose a great threat to the environment. Where there are a lot of septic tanks, the combined discharges can have an effect on the quality of groundwater and of watercourses that pass through the area.
Your environmental regulator needs to know where they are located and how many there are. This is in order to make decisions about whether allowing other activities, or discharges, will cause pollution problems for groundwater, streams or rivers or lochs/loughs.
You can check if your tank has already been registered by contacting your environmental regulator. If you are unsure then it is best to check and avoid making an unnecessary payment. The NIEA and SEPA have records of all registered septic tanks.
If your tank is not registered then you must register it with your environmental regulator.
