The Bio-Pure is a small packaged sewage treatment plant, which can discharge directly to surface water (and groundwater) as it is treated. As the owner of the Bio-Pure, it is your responsibility to check whether you need to obtain a permit to discharge (consent to discharge), or whether you are exempt. It is illegal to discharge sewage effluent without a registration (of exemption) or permit. Failure to register or obtain a permit may result in enforcement action by the Environment Agency.
The rules for discharging sewage effluent in England and Wales have recently changed (6th April 2010) under The Environmental Permitting Regulations 2008. You will now need to apply for a permit to discharge from your sewage treatment plant. However, there are circumstances where a permit is not necessary and an exemption may be obtained instead.
