National Diploma in Drinking-Water (Level 5) with strands in DrinkingWater Assessment, and Water Treatment
Level
5
Credits
159-164
Purpose
This qualification is intended for people who either wish to work as Ministry of Health
drinking-water assessors, or who are working in a supervisory or sole charge position in
water treatment plants.
The core compulsory section is designed to recognise knowledge of the management of
water treatment processes, preventative maintenance and monitoring of product
standards, the Health (Drinking-Water) Amendment Act 2007, the management of water
treatment plant waste processes, process control including Piping and Instrumentation (P
and I) drawings and Supervisory Control And Data Acquisition (SCADA), the DrinkingWater Standards for New Zealand (DWSNZ), Public Health Risk Management Plans
(PHRMP), drinking-water contaminants of public health significance, and team leadership
skills.
The Drinking-Water Assessment strand recognises the industry-specific knowledge and
skills essential for competence as a Ministry of Health drinking-water assessor.
Candidates will be able to assess a drinking-water treatment plant for optimisation and a
drinking-water supplier’s PHRMP for adequacy; assess competence of field analysts; plan
and conduct inspections of drinking-water supplies and verify compliance with PHRMP
and DWSNZ; produce a final report on drinking-water supply inspection findings; use a
Water Information New Zealand (WINZ) database; and prepare a PHRMP. Candidates
will have knowledge of drinking-water supply reticulation systems and reticulation system
management.
The Water Treatment strand recognises the skills required of people working in a
supervisory or sole charge position in water treatment plants. Candidates will be able to
report on a water supply topic or improvement and manage workplace health and safety.
The standards in Elective 1 and Elective 2 of the Water Treatment strand are designed to
recognise the site-specific knowledge and skills required by individuals on the plant or
plants at which they they operate.

Previous versions of the qualification
Version 2 was issued following revision to update the certificate statement and include the
transition information regarding non-NQF certificates offered by Opus International

outcome of standard 21335 is acceptable to Agriculture Industry Training Organisation as
an alternative for standard 17497.
This transition has been included to ensure that all candidates currently enrolled in
versions 1 and 2 are able to complete the requirements of that version if they wish to.
Candidates must complete standard 21335 by 31 December 2012 or transfer to version 3
of the qualification.
Versions 1 and 2 of the qualification contain an expired standard that has been replaced.
For the purposes of these versions of the qualification, people who have gained credit for
the replacement standard are exempt from the requirement to gain credit for the replaced
standard – see table below.
