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.

My Year at NetRegs, A reflection on my time as an intern with the NetRegs team at SEPA. An overview of all the activities and projects I had the opportunity to participate in during my Bright Green Environmental Placement.
