PURPOSE OF THE UNIT STANDARD

A qualifying learner in combination with context expertise standard(s) will be able to explain the elements of water purification and the purpose of the works. This competence will enable the learner to understand the purification process including the purpose of purifying water and alternative methods for making drinking water safe. This will contribute to creating community awareness regarding safe drinking water. In acquiring this competence the qualifying learner will lay a good foundation for future learning and action, and better understand the broader context of water quality and water purification.

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD:

This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
