For the purpose of this guideline the term ‘wastewater’ refers to any discharge to the sewerage system that is in addition to sewage from domestic toilets, bathrooms or laundries.

Hotel and lodge style residential and commercial service buildings (such as cafes, restaurants, laundries) tend to discharge wastewater that has characteristics that are different from normal domestic sewage. These discharges can contain higher proportions of food particles, oils and grease, phosphorus and other chemicals used in a variety of processes.

The Perisher Valley Sewage Treatment Plant (STP) is operated by NPWS and treats all sewage and wastewater from the resort areas of Perisher Valley, Blue Cow, Smiggin Holes and Guthega. The STP uses a biological process to treat sewage and wastewater to a high standard prior to discharge into Perisher Creek. Due to the environmental significance of the area, the STP has to meet stringent regulatory requirements to ensure the water quality of Perisher Creek and amenity of the resort areas is maintained.
