Electrician / Mechanic

Electricians and mechanics play a vital role in Hawaiʻi’s water and wastewater systems. They help build and maintain the infrastructure needed to treat water, recover resources, and ensure safe, reliable service across our islands. In Hawaiʻi’s unique environment these professionals install, troubleshoot, and maintain the mechanical and electrical systems used in water treatment, wastewater management, and power generation facilities. Their work supports public health, environmental protection, and community resilience.

Education & Training

This position typically requires a high school diploma or GED. Preference may be given to candidates with:

  • An associate degree or trade certification in electrical or mechanical systems.

  • Completion of a registered apprenticeship program (typically 4+ years).

  • Experience working in water, wastewater, or utility infrastructure in Hawaiʻi.

Training programs may also be available through the University of Hawaiʻi Community Colleges, union apprenticeship programs, or local workforce development initiatives that focus on environmental infrastructure.

Knowledge, Skills & Abilities

Knowledge of:

  • Electrical and mechanical systems used in utility plant operations, especially those adapted for Hawaiʻi’s island infrastructure.

  • Shop math, tools, and theory, including safety practices for working in humid or salt-air environments.

  • Proper use of testing and diagnostic equipment.

  • The National Electrical Code and safety standards (e.g., NFPA 70E).

  • Installation and maintenance of wastewater facilities, hydroelectric, solar, diesel, and other energy systems used in Hawaiʻi’s rural and off-grid areas.

  • Programmable logic controllers (PLCs), relay ladder logic, and hydraulics/pneumatics in water and wastewater equipment.

  • Basic materials science, including corrosion-resistant materials suited for coastal and volcanic zones.

Skill in:

  • Performing safe and effective mechanical and electrical work in water and wastewater treatment settings.

  • Installing, troubleshooting, and maintaining systems that serve both densely populated areas and remote communities.

  • Reading blueprints and wiring diagrams, and adapting designs to diverse terrains and environments.

  • Estimating labor and material needs for projects—particularly where barge delivery, inter-island transport, or limited access are factors.

  • Safe operation of vehicles and equipment in varying conditions across the islands.

Ability to:

  • Keep detailed records and produce as-built drawings and reports for permitting or regulatory compliance.

  • ​Learn and maintain hydroelectric or alternative energy systems unique to Hawaiʻi (e.g., kuleana systems, microgrids and decentralized wastewater systems).

  • Install and maintain electrical equipment in treatment plants and pump stations.

  • Troubleshoot power failures or control issues.

  • Ensure compliance with safety codes and environmental regulations.

  • Work closely with operators and engineers to keep systems running efficiently.

  • Collaborate with other team members and mentor junior workers, including those in workforce training or apprenticeship programs.

  • Communicate clearly and respectfully with team members and community members, including those in rural or Native Hawaiian communities.
