The Infrastructure Industry Training Organisation has completed the review of the unit standards listed above.
Date new versions published March 2017
Planned review date December 2021
Summary
Gazetted coverage of the Water Industry, including Water Treatment and Drinking-Water, was transferred to Infrastructure ITO in May 2015. Review of the unit standards had been due, but this and the transfer of responsibility was delayed due to TRoQ. The review was conducted in 2016 to align the unit standards with current industry need and to support the New Zealand Certificate in Water Treatment (Small Scale Systems Operator) (Level 3) [Ref: 2240], the New Zealand Certificate in Water Treatment (Drinking-Water/Wastewater) (Level 3) [Ref: 2241], the New Zealand Certificate in Water Treatment (Level 4) with strands in Drinking-Water Treatment, Wastewater Treatment, Drinking-Water Multistage Process, and Wastewater Multistage Process [Ref: 2242], and the New Zealand Diploma in Water Treatment (Level 5) with strands in Drinking-Water Treatment, and Wastewater Treatment [Ref: 2245].
In 2016, a Water Treatment Industry Working Group comprised of industry experts and tertiary providers met to review the structure, levels, credits, and content of the unit standards to update and align with current industry practice. The draft standards were then circulated to wider industry including industry peak bodies, wastewater treatment plant staff, providers, and district and regional councils for further consultation and feedback.
The review took place as part of a larger review of all standards within the Water Industry subfield, which included aligning levels and credits to achieve parity between similar skill sets across the industries and to support the qualifications. Additionally, the focus on processes within the qualifications led to an industry wide decision to combine theory and practical aspects associated with treatment processes into single unit standard for each process. The decision was made to move standards from the Drinking-Water domain to the Water Treatment domain to align with recognised industry terminology and qualification titles.
Main changes
· Updates were made to titles, purpose statements, explanatory notes, outcomes, and evidence requirements to align the standards with current industry practice.
· Theory and practical process unit standards were combined and allocated levels and credits appropriate to the required knowledge and skills.
· Process-based standards were written more broadly to allow for different practices across the industry, and seven new process standards were developed to cover all water treatment processes at both operational and supervisory/management levels.
· Levels and credits were adjusted to align with similar skill sets across the industries and to more appropriately reflect content.
· Seven new standards were developed to address emerging skills and identified gaps within the current suite.
· Four standards were moved from the Drinking-Water domain to the Water Treatment domain to align with industry terminology.
· One standard was moved from the Drinking-Water domain to the Drinking-Water Assessment domain to align with its usage.
· 10 Drinking-Water standards were replaced by standards in the Water Treatment domain.
· Two standards will expire and not be replaced.
· A last date for assessment of superseded Category B standards was specified.
Category C and D unit standards will expire at the end of December 2018.
