National Diploma in Wastewater Treatment (Level 5)
Level / 5Credits / 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].
