Elements and Performance Criteria

The Range of Variables explains the contexts within which the performance and knowledge requirements of this standard may be assessed. The scope of variables chosen in training and assessment requirements may depend on the work situations available.

What drainage and collection systems may be relevant to this standard?
Drainage systems may include surface drains, culverts, mole drains, sand slit, sub-surface traps, pit and trap systems, dune and swale systems, reed beds, water-recycling pumps and baffles.

What might an inspection of drainage reveal?
Inspection may reveal surface pooling, waterlogging (soil moisture), water table depth, testing of surface and subsurface infiltration rates, and symptoms associated with excessive leachates and nutrients.

What OHS requirements might be relevant to this standard?
OHS requirements may include safe systems and procedures for outdoor work, including protection from solar radiation, dust and noise, protection against chemical residues, including that in/on foliage, water, soil and other items, and the selection, use and maintenance of relevant personal protective clothing and equipment.

What measuring equipment might be used?
This may include tensiometers, probe tubes, flow meter, catch cans and pressure gauge, test wells and fault meter.

What factors external to the system may cause interference?
These may include pests and vermin (tortoises, yabbies, ants, spiders, snails, rabbits, hares, foxes, wasps, rose weevil, earwigs, snakes, carp, pigs, wallabies, eels, rats, mice, kangaroos, dogs, cats, parrots), organic (leaves, slime, weeds, algae, sticks, crop residue), weather, channel regulators (if applicable), fire, mechanical damage (if applicable), power spikes, power failures, storm run off/system breakage, thatch, runoff from adjacent areas and rising water tables.

What drainage system parts may be relevant to this standard?
These will vary according to brand and supplier and may include injectors, pumps, and tensiometers, probe tubes, flow meter, computer and/or other scheduling devices, recycling equipment and spray equipment.

What water quality measures might be relevant to this standard?
These include salinity and electro conductivity, pH, sodicity, chloride, calcium carbonate, iron, turbidity, nutrients and pesticides.

What soil moisture measuring devices may be used?
These may include subjective measurement, gypsum blocks, tensiometers, enviroscan, neutron probe TDR (time domain reflectometer).

What evidence is required to demonstrate competence for this standard as a whole?
Competence in measuring drainage system performance requires evidence that a person can identify and correct system problems, measure, record and report soil moisture, salinity and water table depth to determine system performance and efficiency.
The skills and knowledge required to measure drainage system performance must be transferable to a different work environment. For example, this could include different drainage systems and components, crops/planted areas and enterprise procedures.
What specific knowledge is needed to achieve the performance criteria?

Knowledge and understanding are essential to apply this standard in the workplace, to transfer the skills to other contexts, and to deal with unplanned events. The knowledge requirements for this competency standard are listed below:

OHS guidelines
measuring and monitoring procedures for factors contributing to drainage system performance
positive and negative environmental impacts of drainage systems
water table and salinity measures
water quality monitoring methods and techniques
soil moisture measurement procedures
water authority standards and procedures
enterprise policies and procedures.

What specific skills are needed to achieve the performance criteria?

To achieve the performance criteria, appropriate literacy and numeracy levels as well as some complementary skills are required. These include the ability to:

apply measuring and testing techniques
record and report system performance
identify adverse environmental impacts of drainage systems and appropriate remedial action
use computers for recording and reporting drainage system data
implement and follow relevant enterprise OHS and environmental policies and procedures.

Are there other competency standards that could be assessed with this one?

There are a number of processes that are learnt throughout work and life, which are required in all jobs. They are fundamental processes and generally transferable to other work functions. Some of these are covered by the key competencies, although others may be added. The questions below highlight how these processes are applied in this competency standard. Following each question a number in brackets indicates the level to which the key competency needs to be demonstrated where 0 = not required, 1 = perform the process, 2 = perform and administer the process and 3 = perform, administer and design the process.
