Trade Waste Customer Categories
Liquid Trade Waste services are provided using the following categories. These categories reflect the risk associated with providing a trade waste service to different types of customers:
CATEGORY 1: LOW VOLUME AND LOW IMPACT LIQUID TRADE WASTE -
Liquid trade waste considered to be different in strength and/or volume to domestic liquid waste with lower strength and/or volume characteristics than that of Category 2.
CATEGORY 2 LOW TO MEDIUM VOLUME AND LOW IMPACT LIQUID TRADE WASTE -
Liquid trade waste with characteristics considered to be greater in strength and/or volume than domestic liquid waste that is considered to have a low impact.
CATEGORY 3: LOW TO MEDIUM VOLUME AND MEDIUM IMPACT LIQUID TRADE WASTE -
Liquid trade waste with characteristics considered to be greater in strength and/or volume than domestic liquid waste that is considered to have a medium impact.
CATEGORY 4: HIGH IMPACT LIQUID TRADE WASTE -
Liquid trade waste of any volume or strength considered to have a high impact.
Using the National Wastewater Source Management Guideline (WSAA; July 2008), customers are categorised according to the risk the activity presents in the particular wastewater catchment.
