2 NZQF NQ Ref 0966 Version 5 Page 2 of 7 National Diploma in Wastewater Treatment (Level 5) Level 5 Credits 131 Purpose This qualification is intended for supervisors or people in a sole charge position in wastewater treatment plants. The compulsory standards recognise knowledge of various wastewater treatment processes including interpreting test results relating to each process, optimising processes as a result of monitoring and their critical points, process control and Supervisory Control And Data Acquisition (SCADA), the impact of effluent discharge on the environment, and the characteristics of wastewater. Candidates are also able to manage workplace health and safety, lead a group or team in a complex work environment, and write a report on a wastewater treatment plant topic or improvement. The elective section is designed to recognise the skills related to managing, monitoring, and optimising processes at the candidate s own wastewater treatment plant, or plants which they operate. Candidates will also be able to assess a wastewater treatment plant for optimal output, interpret data to determine the effect of effluent discharge on the environment, and manage wastewater reticulation systems and critical points. This qualification builds on the knowledge and skills in the National Certificate in Wastewater Treatment (Level 4) [Ref: 0879]. Credit Range Compulsory Elective Level 4 credits 20 - Level 5 credits Minimum totals Total 131 Requirements for Award of Qualification Award of NZQF National Qualifications Credit gained for a standard may be used only once to meet the requirements of this qualification.
