Many successful candidates have completed a trade apprenticeship in plumbing or a related field, though on-the-job training is provided. Some positions may require or prefer journeyperson certification in plumbing or waterworks maintenance, depending on the specific posting and province. Once hired, you will receive comprehensive training on DND-specific systems, safety procedures, and equipment operation. The Department supports ongoing professional development through technical courses, certifications in water treatment and distribution systems, and opportunities to advance your credentials. You may also pursue additional certifications such as Water Distribution System Operator or Waterworks Technician designations offered through provincial trade associations.
Entry Plans
You can enter this career through several pathways within the federal Public Service. Most positions are filled through open competitions advertised on the Government of Canada Job Bank (jobs.gc.ca) where you can apply directly. The DND also maintains talent pools for Waterworks Maintenance Workers, allowing qualified candidates to be considered for positions as they become available without reapplying. If you are a Canadian Armed Forces member, you may transition into this civilian role through military-to-civilian career transition programs. Recent high school graduates and apprentices can explore opportunities through DND's recruitment initiatives. Some positions may be filled through internal lateral moves from related trades within the Public Service. We encourage you to create a profile on the Government of Canada Job Bank and monitor postings for DND facilities in your region.
Part-Time Options
Waterworks Maintenance Worker positions with DND are typically full-time permanent or indeterminate appointments. However, the Department does occasionally offer term positions that may provide flexibility in work duration. Due to the essential nature of water system maintenance, positions often require shift work including early mornings, evenings, nights, and weekend coverage to ensure continuous system operation. Remote work is not applicable to this role as your work requires physical presence at water infrastructure sites and mechanical facilities. Some flexibility may be available regarding schedule rotation preferences based on operational needs and seniority. We recommend discussing scheduling options and shift patterns during the recruitment process with the hiring manager at the specific DND location.
