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 2020 Liquid Trade Waste Management Guidelines (soon to be released).

Resulting qualification

NOTE: For the 2020 calendar year, if this course is offered it will not be as a Nationally Accredited course (i.e. not a Certificate IV course). This is due to changes introduced in 2019 relating to third party agreements with registered training organisations. The DPIE course content will not change from 2019 and the courses remain a suitable qualification for LWU trade waste officers in regional NSW.

A Certificate of Completion – Liquid Trade Waste Regulation will be issued to each successful candidate.
