Do I need any licenses for a sewage treatment tank?
Anyone with a septic tank or a sewage treatment plant is under legal obligation to have their system registered with their local Environmental Health Agency. Failure to register is considered a criminal offence.
Should your sewage treatment tank or septic tank sit close to a local water source or flow into it, it is a mandatory requirement to inform the Environmental Health Agency. You may require a permit to continue using the system if you cannot connect to municipal foul water systems.
Upon registering your septic tank or sewage treatment tank, the Environmental Health Agency will advise you on whether you require a permit or not.
