Review of Skill Set and Unit of Competency Public Comment

AUSJET / ADCVA initiated a review of the skill sets associated with for the following courses through IBSA, due to an change in the requirements of the technical drawing units of competency contained within the skill set.

Skill sets reviewed:

• MSMSS00003 Use high pressure water jetting equipment

• MSMSS00004 Operate a high pressure water jetting system

• MSMSS00005 Operator a drain cleaning system

• MSMSS00006 Operate a vacuum loading system.

As part of that review the following units of competency were also reviewed and updated

Units of competency reviewed:

• MSMWJ201 Use high pressure water jetting equipment

• MSMWJ301 Operate a high pressure water jetting system

• MSMWJ302 Operator a drain cleaning system

• MSMWJ303 Operate a vacuum loading system.

The review is now complete and open for public comment.

During the review it was noted that there was a gap within the current skills set and units of competency in respect to Hydro Excavation activities that utilise smaller pressure/volume combination Class B pumps. As a result AUSJET / ADCVA submitted a proposal to IBSA to include a new unit of competency and skill set FOR Hydro Excavation in the current project.

It is important as an industry that we support both the changes to the existing skills sets and units of competency, and the introduction of a new skill set and unit of competency for Hydro excavation. This will allow companies performing Hydro Excavation with Class B pumps to fully comply with AS/NZS 4233:2013.

Please find below link to the consultation paper and proposed changes to the skills set and units of competency for public comment. We would request both members and non-members involved in the industry review the changes and the proposed additions in relation to Hydro Excavation, and provide comment if necessary.

Please email your feedback to by Friday 26 June 2020.

IBSA will also be holding a consultation session via Zoom on Wednesday 24 June from 1.30 pm to 3.30 pm (AEST). If you’d like to participate in this session register your interest by emailing by COB on Wednesday 17 June.

Please note:  A safety component is also expected to be delivered.

Once training is complete and the trainee has worked with the potential employer (our member) for an eight week period the potential employer can then choose whether the trainee is suitable for future employment.  The potential empoyer has no obligation to employ the trainee at the end of the eight week period.

How to apply?

AUSJET are currently in discussions with our Gladstone, Queensland based members to take part in the program during the months of February and March 2020. If you’re based in Central Queensland and would like to take part in the program or find out more please email

Skilling South Australia

Skilling South Australia is investing in apprentices and traineeships to grow business, the economy and keep young people in South Australia. Skilling South Australia Projects are Government-funded projects, co-designed with business and industry, to drive apprenticeship and traineeship growth.

Funding is available for projects that drive apprenticeship and traineeship growth in the state.

The aim of the project is to:

  • boost regional apprenticeships or traineeships
  • support strategic industry sectors, such as defense, information technology, cyber security and disability services, or
  • assist specific cohorts, such as Aboriginal and Torres Strait Islander job seekers, women in non-traditional trades or long-term unemployed job seekers into apprenticeships or traineeships.

AUSJET and ADCVA are currently applying for the program to assist our members in finding apprentices. Several of our member business in South Australia who are interested in employing an apprentice have been approached. If AUSJET’s and ADCVA’s application is approved an advert will be formulated asking for potential apprentices to apply. Those selected will go through a training process and be trained in the:

  • MSMSS00003 - Use High Pressure Water Jetting Equipment.

The training will take place at the potential employer’s place of business. If the employer (our member) is impressed with the trainee they then decide as to whether to offer an apprenticeship to the applicant.

AUSJET/ ADCVA Partnering with UNSW Proposal and Scope

Research Paper on the Effects of High-Pressure Water Hydro Excavation (NDD) on Underground Assets.

The Australian High Pressure Water Jetting Association (AUSJET) incorporating, Australasian Drain Cleaning and Vacuum Association (ADCVA) would like to propose a partnership with the UNSW and in particular utilise the resources of: Professor Jun Wang, BE, PhD(Melb), FIEAust, CPEng, FISNM for a research study on the effects of Hydro Excavation - Non Destructive Digging (NDD) on underground assets.

AUSJET / ADCVA are planning a project to look at the effect of water jetting pressures on different infrastructure assets, when carrying out Hydro Excavation (NDD). Hydro Excavation (NDD) utilises high pressure water usually in the range of 2000psi to 8000psi, the high-pressure water is used in conjunction with vacuum to locate and expose assets in a passive non- destructive method during civil construction projects and underground maintenance work.

There are varying theories what type of pressure/flow can be used on specific assets, there is some information going around that no more than 2000psi should be used. This was based on a non-published trial completed on a fibre optic cable, the issue with this trial, it’s not only pressure that can damage an asset, but also the technique, water flow and jet size weren’t considered. If a high-pressure lance sits stationary long enough on an asset, at some point it will cause damage. In addition, the type of nozzle being used can have an effect, for example a pin nozzle is more concentrated in one spot however a turbo nozzle that spins can be used to minimise impact on the asset, whilst still being productive.

Hydro Excavation (NDD) is used extensively throughout the world, Australia, North America, Europe, UK, Asia and Canada and to our knowledge no organisation has ever completed a comprehensive study on pressure/flow/ nozzle size/techniques to be used regarding different asset material types.

AUSJET/ADCVA would like to facilitate a partnership with the UNSW, contracting companies and other Industry Associations in a research study that focuses on the following Scope:

  • Pressure – what pressures are causing damage to different underground services pressure range from starting 100-1000bar;
  • Water flow – what is the optimum water flow for each asset flow range 10 – 40 litres per minute;
  • Nozzle Size – How does that play a part in optimizing productivity but not damaging the asset;
  • Single jet turbo nozzle, pin jets, fan jets, – what is the time differences with regards to damage of the asset;
  • Technique – are their differing techniques to best protect the asset and reach improve production;
  • What innovative automation technology can be introduced to take the operator away from the lance.

AUSJET/ADVCA proposes the studies be carried out on the following materials and asset types including but not limited to on:

  1. Fibre Optic Cable / Telecommunications: Direct Buried & Polyvinyl Chloride (PVC),
  2. Underground Power Cable: Polyvinyl Chloride (PVC),
  3. High Voltage & Low Voltage electrical cable: Polyvinyl Chloride (PVC),
  4. Potable Water Pipes: Copper Pipes, Galvanized Steel, Cast Iron, Polyvinyl Chloride (PVC), CPVC Plastic, Cross-Linked
  5. Storm Water Mains: Concrete, Polyvinyl Chloride (PVC), Vitrified clay
  6. Sewer Mains: Asbestos Cement, Cast Iron, Ductile Iron, Polyethylene, Polyvinyl Chloride (PVC), Polypropylene, Polyvinylchloride-Unplasticised, Vitrified Clay
  7. Gas Mains: Steel, Coated Steel, Coated Steel, Polyvinyl (VC), Cross-Linked Polyethylene.

Ideally the study would be completed within 12 months or have initial findings within 12 months with the complete study to take no longer than 3 years.

AUSJET/ADCVwill provide samples of these assets for UNSW to run tests, also AUSJET / ADVCA along with its members will facilitate operational displays, live job site studies for the researcher to get a good feel for how the work is performed in the field and what the challenges are, technical information around pump sizes and water flow.

AUSJET/ADVCA along with its members can provide Class A and Class B training for the researcher.

AUSJET/ADCVis planning on hosting a conference in March 2021 and would like to advertise that this paper or initial findings will be completed, and Professor Jun Wang will present it at the conference.

AUSJET/ADCVproposes that an agreement with the UNSW be reached so that both organisations have access to the published paper and are authorized to circulate the paper where they see fit.
