CPCPDR4013 - Design and size domestic treatment plant disposal systems
Overview
This unit specifies the skills and knowledge required to design, size and document the layout of domestic treatment plant disposal systems for a residential design that comprises a dwelling (Class 1a).
Assessment
For Melbourne campuses
Assessment tasks will be designed to reinforce & extend knowledge and skill competence within set & controlled parameters in accordance with each unit’s learning outcomes & performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.
Students will be expected to demonstrate the following required skills:
*designing, sizing and documenting the layout of a treatment plant disposal system for a residential design that comprises a dwelling (Class 1a), including details of:
- treatment plant
- disposal field
- relationship of the above to any buildings, property boundaries, easements and other structures.
Students will also be expected to demonstrate the following knowledge:
*design concepts and performance measures for domestic treatment plant disposal systems
*principles of the assessment of land capability for application of effluent
*principles, techniques and characteristics of effluent treatment and disposal, including the purpose of anaerobic bacteria
*properties and characteristics of landscape application areas
*site characteristics that may influence planning:
- contour, reduced and invert levels
- type of system chosen
- soil category
- design loading rates (DLR)
- long term acceptance rate (LTAR)
- number of people the system is to cater for
*identifying scope of work by waste processing method: - absorption by absorption trenches or transpiration beds
- disposal by absorption, spray or recycling
- anaerobic or aerobic action
*drawing instruments and sketching techniques, including the use of conventional symbols
*use of computers for documentation
*computer-aided design (CAD) software
*how to access relevant information, including codes and standards
*tools, materials and equipment used to design, size and document the layout of domestic treatment plant disposal systems
*work health and safety (WHS) requirements for designing, sizing and documenting the layout of domestic treatment plant disposal systems.
