While you may attach a resume, it will not replace a completed application. Incomplete applications will not be considered.
Do you have hands-on experience with engines, pumps, valves, hydraulics, or industrial equipment? If so, we may have the perfect opportunity for you! Arlington County's Department of Environmental Services (DES) is seeking skilled mechanics and maintenance professionals to join the Water Pollution Control Plant (WPCP) as Wastewater Maintenance Technician/Trainees (WMT) through a paid apprenticeship program! The WPCP is a state-of-the-art, highly automated advanced wastewater treatment facility capable of treating more than 40 million gallons of wastewater per day. Selected candidates will participate in a structured four-year job training/work apprenticeship program, which offers a career path from Wastewater Maintenance Technician/Trainee to the highest-level Wastewater Maintenance Technician at full performance.
The apprenticeship program includes:
  • Extensive County-paid technical courses and training using the TPC training system, such as wastewater systems overview, safety, CMMS, WEF pump computer, backflow preventer, crane truck/backhoe/skid loader/rigging/overhead crane operation, laser alignment, vibration analysis, root cause failure, oil analysis, and other required trainings;
  • A structural and pipe welding certification and CDL License;

  • A compensation plan based upon the achievement of new skills through comprehensive testing, certification, and demonstrated application of skills.

Responsibilities
Specific duties include:
  • Inspecting, diagnosing, and repairing industrial mechanical equipment including pumps, blowers, compressors, valves, gearboxes, conveyors, sluice gates, and diesel/gasoline engines using diagnostic tools, blueprints, and factory specifications;
