Range
Disposal systems refer to solids screening and/or sedimentation and/or clarifiers
and/or polymer flocculants and/or filters and/or bacterial: anaerobic and/or aerobic,
and/or sludge disposal: dewatering and/or centrifudge and digesters and/or pH
correction.

Definition
Organisational procedures refer to documents that include: worksite rules, codes,
and practices; equipment operating instructions; production specifications;
documented quality management systems; and health and safety requirements.
Elements and performance criteria
Element 1
Develop effluent disposal systems.
Performance criteria
1.1
Plant effluent disposal system requirements and operating parameters are
identified and documented.
Range
1.2
Final discharge points from effluent disposal system are identified.
Range
1.3
discharge points – rivers and/or sea and/or sewerage and/or
treatment plants and/or air.
Planning consent is obtained from local bodies prior to commencement of
project.
Range
1.4
parameters – water flow and/or biological oxygen demand (BOD)
and/or chemical oxygen demand (COD), suspended solids and/or
settleable solids and/or pH, dissolved oxygen and/or pond level
and/or pond pH and/or percentage of BOD removed and/or plant
load and/or plant load variance.
local bodies – regional council and/or district authority.
Opportunities to develop effluent disposal system with recovered product are
maximised.
Range
products – biogas and/or solids for stockfoods.

1.5
Effluent disposal system selected is based on considered constraints.
Range
1.6
Resources required for development of effluent plant system is based on
organisational preferences and constraints.
Range
1.7
constraints – time and/or budgetary.
Initiation of effluent disposal system complies with organisational policies,
procedures, and legislation.
Range
1.8
constraints – availability of land, services; plant load, costs:
continuing operating, labour, operating personnel, contractors;
disposal of waste, performance requirements, Resource
Management Act requirements, economic performance, reliability
of technology, ability to cope with load variance.
policies and procedures – work instructions and/or manuals and/or
operating procedures and/or quality standards.
Communication with parties affected by initiation and development of effluent
disposal system is in a manner and within a timeframe that maintains positive
relationships and minimises delays to development.
Range
parties – neighbours and/or consultants and/or regional councils
and/or district authorities and/or legal authorities.
Element 2
Implement effluent disposal systems.
Performance criteria
2.1
Developed effluent disposal system is implemented within agreed timeframes.
2.2
Developed effluent disposal system discharge conforms to local authority and
resource management requirements.
2.3
Operating costs of effluent disposal system are minimised and recoverable
costs maximised.
2.4
Environmental impact of developed effluent disposal system is minimised.
2.5
Continuous monitoring of developed effluent disposal system operation is
maintained and results are within specified parameters.
Range
parameters – water flow and/or biological oxygen demand (BOD)
and/or chemical oxygen demand (COD), suspended solids and/or
settleable solids and/or pH and/or dissolved oxygen and/or pond
level and/or pond pH and/or percentage of BOD removed and/or
plant load and/or plant load variance.

2.6
Implementation of effluent disposal system complies with organisational
policies, procedures, and legislation.
Range
policies and procedures – work instructions and/or manuals and/or
operating procedures and/or quality standards.
2.7
Opportunities to improve operation of effluent disposal system are identified,
and are implemented within a timeframe that optimises performance of system.
2.8
Variations in specified technical performance of effluent control system are
identified, and action taken minimises production of discharge outside specified
operating parameters.
Please note
Providers must be accredited by NZQA, or an inter-institutional body with delegated
authority for quality assurance, before they can report credits from assessment against
unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by NZQA before they can register
credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP also includes useful information about special requirements for organisations
wishing to develop education and training programmes, such as minimum qualifications for
tutors and assessors, and special resource requirements.
