Liquid Trade Waste Regulation (5 days)

The Best-Practice Management of Water Supply and Sewerage Guidelines 2007 requires NSW local water utilities to implement an appropriate liquid trade waste policy; issue an approval under the Local Government Act 1993 for each liquid trade waste discharger to its sewerage system; and to implement best-practice sewerage and trade waste pricing. These requirements comprise the NSW Framework for Regulation of Sewerage and Trade Waste, which is set out in the 2009 Liquid Trade Waste Regulation Guidelines.

The Liquid Trade Waste Regulation course is designed to provide training in the competencies required for the regulation of sewerage and liquid trade waste discharges to the sewerage system in regional areas of NSW and implementation of the 2009 Liquid Trade Waste Regulation Guidelines.

The course aligns with the requirements of the National Water Training Package and fully addresses elective and core units of competency of the Certificate IV qualification under the National Water Training Package, December 2015.

On completion of the course you'll have the knowledge and skills essential to implement best practice trade waste regulation and pricing.

The department also runs a two-day Overview of Liquid Trade Waste Regulation course (days 1 and 2 of the Liquid Trade Waste Regulation course). A link to more information on this course can be found at the bottom of this page.
