Plumbing Apprenticeship
Plumbing Green Applications

Introduction & Background
Green jobs are in demand. But most are not new occupations. They are traditional occupations, upgraded with
skills training in new technologies that promote renewable energy and energy efficiency. Therefore, providing
“green” training is the focus of the Wisconsin Sector Alliance for the Green Economy (SAGE) project, a federal
grant implemented by the Wisconsin Bureau of Apprenticeship Standards.
SAGE includes the plumbing trade to prepare future plumbers to install and maintain green technologies and
systems. Industry drives apprenticeship, and enhancing the plumbing apprenticeship was no exception. After
skilled plumbers and WTCS instructors analyzed and determined the training needs, they developed the
curriculum.


INDUSTRY FOCUS GROUP
The Plumbing Industry Focus Group met March 14, 2011 to identify green trends in the plumbers trade and
recommended additions and/or revisions to the apprenticeship curriculum. The meeting outcomes provided
the foundation and blueprint for enhancing the apprenticeship curriculum. Step 1 was to analyze the
occupation and its green trends. Step 2 was to design and develop the new curriculum. Step 3 will be to rollout
the curriculum, train instructors, and obtain the necessary approvals needed to implement a green-skills
focused curriculum.
The group reached consensus on adding a new Plumbing Green Applications 72 hour course to the plumbing
apprenticeship. This course focuses on water conservation, efficiency, and new technologies such as solar
thermal water heating.


CURRICULUM DEVELOPMENT
The design team, consisting of industry representatives and instructors, worked through January 2012 to
develop student learning plans, teaching plans, learning materials and assessment strategies for use in the
apprenticeship related instruction classroom. The course can be incorporated into existing apprenticeship
programs to meet the needs of local employers. Beginning in the fall semester of 2012, the course will be
available to incorporate into various semesters during the 572 hours related instruction portion of the
apprenticeship programs offered at all 16 of the Wisconsin Technical Colleges. In 2011 – 2012, the new
modules will benefit more than 500 Plumbers Construction and Plumbers Service apprentices, and be made
available to journey workers through special upgrade sessions.


STATE COMMITTEE APPROVAL
The State Apprenticeship Committee approved incorporating the 72 hour Plumbing Green Applications course
into the plumbing apprenticeship-paid related instruction at their October 2011 meeting.

Water Quality and Reuse
Based on information in "Water Reuse: an Introduction" by Tom Braun, Plumbing Consultant, Wisconsin
Department of Safety & Professional Services Safety & Buildings Division
Why reuse water?
        The social, economic, and environmental impacts of past water resources development and
           inevitable prospects of water scarcity are driving the shift to a new paradigm in water resources
           management: WATER REUSE

Types of Water Reuse:
          Storm Water
               Grey Water
               Black Water

New Approaches:
        Augmenting water sources;
               Substituting reclaimed/reuse water for applications not requiring drinking water;

Resulting in:
               Protecting ecosystems by decreasing diversion of freshwater;
               Reducing the quantity of nutrients and other contaminants entering water sources

Technologies
         Water conserving fixtures, appliances, and equipment.
               Agriculture
               Desalination
               Preserving the highest quality water sources for drinking water and using alternative sources for
                other applications

Water reclamation and reuse considerations:
         Public Health
               Infrastructure
               Treatment Process Reliability
               Economics
               Public Policy

Definitions:
               Sustainability: Optimizing the benefits of a present system without diminishing the capacity for
                similar benefits in the future.
               Reclaimed water: Municipal wastewater that has gone through various treatment processes to
                meet specific water quality criteria with the intent of being used in a beneficial manner. The term
                recycled water is used synonymously with reclaimed water.
               Water reuse: The use of treated wastewater for a beneficial use.
               Water footprint, the term that accounts for the direct and indirect use of water by an individual
                or business.




                                                         47
Water Usage:
        Water usage is related to energy use and greenhouse gas emissions. Water is associated with
           energy — energy used for pumping, treating, filtering, chilling, and heating water. It is clear that
           unnecessary water use means unnecessary energy use.
            Individuals, businesses and industry may want to make appropriate changes to offset their
             overlooked water footprint.

Regulations & Guidelines:
         EPA:
                o Reclaimed Water Guidelines
            UPC:
                o       Reclaimed
                o       Reuse water
                o       Green
            IPC:
                    o   Gray water
            Wisconsin:
                 o SPS 382.70 Performance based
                 o Attractive alternative encourage innovation
            California: Reclaimed water 22
                  o Reclaimed water: Municipal wastewater that has gone through various treatment
                      processes to meet specific water quality criteria with the intent of being used in a
                      beneficial manner. The term recycled water is used synonymously with reclaimed water.
                  o Water reuse: The use of treated reclaimed water for a beneficial use.
                  o Onsite Water Reuse: Wastewater that is produced and collected onsite that has gone
                      through various treatment processes to meet a specific water quality with the intent of
                      being used beneficially on the same site.
