Good Engineering Practice for Northern Water and Sewer Systems

1.6.4 The National Energy Code
The National Energy Code for Buildings was published in 1997, but it has not been adopted
by the NWT. The Energy Code includes prescriptive and performance requirements. The
Energy Code with associated software, including a construction and energy cost database, is
available to allow an evaluation of the performance of the design. Designers and Project
Managers are therefore encouraged to become familiar with the Energy Code.
1.6.5 The National Plumbing Code
The seventh edition of the National Plumbing Code was published in 1995. The Plumbing Code
specifies the minimum requirements for:
• Drainage systems for water-borne wastes and storm water for buildings to the point of
connection with public services,
• Venting systems,
• Water service pipes, and
• Water distribution systems.
The Plumbing Code has not been adopted in the NWT, although the City of Yellowknife has
chosen to regulate and enforce it. It is recommended for Best Practice purposes that all Designers
and Project Managers become familiar with the National Plumbing Code.
1.6.6 The National Guide to Sustainable Municipal Infrastructure
The National Guide to Sustainable Municipal Infrastructure: Innovations and Best Practices
provide municipalities with the best available technology solutions for addressing municipal
infrastructure development issues such as planning, design, construction, management,
assessment, maintenance, and rehabilitation. To date, twenty-one Best Practices on topics
such as potable water, and storm and wastewater have been published and they can be
viewed online at http://www.infraguide.gc.ca/best.html. Designers and Project Managers are
encouraged to become familiar with the National Guide to Sustainable Municipal
Infrastructure.
1.6.7 Municipal Bylaws
All municipal bylaws and acts must be adhered to in the design and construction of facilities in the
NWT.
