Required Skills

This describes the essential skills and knowledge and their level required for this unit

Required skills

interpret and review hydraulic architectural and site plans

identify and evaluate trade wasteproducing processes

evaluate process inputs and outputs using relevant methodologies such as Mass Balance and Process Yield

apply risk assessment and management based on AS

use flow measuring or flow assessment techniques

use appropriate wastewater sampling and preservation techniques for onsite and laboratory testing

interpret and evaluate sample analysis data

interpret and apply legislation and policies applicable to trade waste

develop monitoring plans and coordinate measuring testing and sampling activities

plan and conduct investigations

assess environmental impact using ISO where appropriate

assess environmental impact using ISO14001 where appropriate

assess waste treatment methods processes plant and equipment

negotiate and communicate

use appropriate personal protective equipment for protection against physical chemical and biological hazards

Required knowledge

relevant legislation

relevant enterprise policies for trade waste management

water quality parameters of significance to the wastewater system

personal protection and safety precautions for wastewater sampling including the requirement for relevant inoculations such as

Q Fever

Hepatitis A and B

Polio

Tetanus

Diphtheria

industrial waste treatment methods and processes for high risk industrial organisations

hydraulics chemistry andor equivalent science

basic knowledge of wastewater collection treatment and disposal systems

investigation procedures

range of appropriate measuring testing sampling procedures

customer expectations and requirements

occupational health and safety legislation

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria Required Skills and Knowledge the Range Statement and the Assessment Guidelines for the Training Package

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The candidate should

demonstrate consistent performance for each element across a representative range of applications

meet the Performance Criteria associated with each element by employing the techniques procedures information and resources available in the workplace from those listed in the Range Statement

demonstrate an understanding of the underpinning knowledge and the application of skills as described under Knowledge and Skills

The candidate should demonstrate the ability to evaluate implement and monitor high risk trade waste approvals including

advising customers of the trade waste management policies and procedures in operation

advising customers of requirements for obtaining and complying with trade waste discharge approvals

assessing and evaluating applications for highrisk trade waste treatment and disposal

implementing charging and monitoring procedures

completing records and reports

Context of and specific resources for assessment

Access to the workplace and resources including

documentation that should normally be available in a water industry organisation

relevant codes standards and government regulations

Where applicable physical resources should include equipment modified for people with disabilities

Access must be provided to appropriate learning andor assessment support when required

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed

Validity and sufficiency of evidence requires that

competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace

where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice

a decision of competence should only be made when the assessor has complete confidence in the persons competence over time and in various contexts

all assessment that is part of a structured learning experience must include a combination of direct indirect and supplementary evidence

where assessment is for the purpose of recognition RCCRPL the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time

assessment can be through simulated projectbased activity and must include evidence relating to each of the elements in this unit

In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge Questioning will be undertaken in a manner appropriate to the skill levels of the operator any cultural issues that may affect responses to the questions and reflecting the requirements of the competency and the work being performed

Method of assessment

The following assessment methods are suggested

assessment in the workplace or in a simulated workplace and under the normal range of workplace conditions

assessment should also be conducted in conjunction with aspects of technical competencies that are consistent with the work environment

techniques for gathering evidence of competency may include

observation of performance

written andor oral questioning to assess knowledge and understanding

completion of workplace documents and reports produced as part of routine work activities

third party reports from experienced practitioners

completion of performance feedback from supervisors and colleagues


Range Statement
