Determine Water Conservation Measures

This unit specifies the competency required to develop skills in effectively increasing water sustainability and care and improving the management of the water cycle.

Plumbers are in direct contact with end users on a daily basis.  A clear understanding of existing water efficient products, emerging technologies, best management practices and existing conservation programs is essential in fostering conservation, developing partnerships with local water utilities and authorities, and increasing business opportunities.

Work associated with this unit is undertaken within the plumbing and services sector in accordance with relevant US standards.

It is a pre-requisite that all participants seeking accreditation in any ‘Course in GreenPlumbers Environmental Solutions’ are required to be licensed and or recognized as a plumber by the Authority Having Jurisdiction.

Nominal Hours - 8
