All premises discharging trade waste to the sewerage system are classified as trade waste customers. Wannon Water is committed to a clear and transparent process in categorising its trade waste customers. Wannon Water will assess all applications to discharge trade waste to the sewerage system taking into consideration:

Trade waste customers are categorised into one of three categories dependent on their load and risk to the sewerage system.  These categories, which create the framework for the form of appropriate trade waste agreement and the pricing structure, are described in the following table: 

 Category  Description
Major trade waste customer Unique flow and/or load possibly requiring infrastructure and/or treatment in addition to current system capacity.
Minor trade waste (pre-treatment) customer Strength of trade waste not of a similar nature to domestic sewage requiring the installation of pre-treatment equipment prior to discharge to Wannon Water’s sewerage system.
Minor trade waste (no pre-treatment) customer Discharge small quantities of trade waste to Wannon Water’s sewerage system and which is of a similar nature to domestic sewage.
