Domestic sewage isn’t classed as trade effluent. This includes waste safely discharged from kitchen sinks, toilets and showers. The main sewage system treats all organic matter therefore we don’t need to run additional biological treatments.
Water companies often classify septic effluent as domestic sewage. Therefore, you do not need to seek legal consent to discharge it. However, companies classify septic tank waste as trade effluent when you dispose of likely polluted material.
