Application
This unit describes the skills required to operate and maintain salt water interception works.
This unit applies to those working as field staff with the responsibility for making decisions relating to maintenance, repairs and operations as well as providing detailed reports on performance and optimisation of the salt interception works.
The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to.
Those undertaking this unit will work independently under indirect supervision while performing routine tasks in a range of familiar contexts.
No licensing, legislative or certification requirements apply to unit at the time of publication.
Elements and Performance Criteria
ELEMENTS | PERFORMANCE CRITERIA |
Elements describe the essential outcomes | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions section. |

2. Operate salt interception works | 2.1 Identify, set or adjust pump station components. 2.2 Carry out routine security inspections and cleaning duties. 2.3 Operate pump station. |
3. Maintain salt interception works | 3.1 Conduct routine maintenance of salinity pump stations. 3.2 Conduct acid dosing of salinity lines. 3.3 Maintain saline water collection and disposal pipelines. 3.4 Conduct repairs to pipe lines and valves. 3.5 Undertake minor civil construction works. |
4. Enhance salt interception performance | 4.1 Gather data and create a report on salt interception scheme performance. 4.2 Optimise salt interception performance. 4.3 Undertake hydraulic performance of saline collection and disposal pipelines. |
5. Compile salt interception reports | 5.1 Collect required data from monitoring points. 5.2 Report salt interception works performance. |
Evidence of Performance
Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the candidate must demonstrate evidence of performance of the following on at least one occasion.
gathering bore data
locking and tagging out of equipment
storing, handling and using chemicals
collecting samples and conducting water tests
maintaining pumps, valves, pipes, dose acids
maintaining bores and piezometers
undertaking minor civil works including at least one of:
pipeline construction
concrete works
metal fabrication
optimising pipelines and pump stations
repairing pipelines and valves
Evidence of Knowledge
Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the depth of knowledge demonstrated must be appropriate to the job context of the candidate.
groundwater hydraulics
pump performance
pipeline hydraulics
chemical handling and dosing
groundwater data collection
environmental impacts of saline water
maintenance scheduling
valve selection and operation
optimisation principles for pump stations and pipelines
legislation relating to salt interception works
Assessment Conditions
Competency should be assessed in an actual workplace or in a simulated environment, with access to equipment and infrastructure appropriate to the outcome. Competency should be demonstrated over time to ensure the candidate is assessed across a variety of situations.
Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
