Mechanical Design Draftsman (Water Treatment Equipment)

Core Role

• Prepare detailed 2D and 3D CAD drawings for water treatment plant components (pumps, tanks, piping layouts, skids, RO systems, clarifiers, aerators, etc.).
• Ensure drawings comply with industry codes and standards (ASME, IS, DIN, BS).

Support engineers by converting process designs into manufacturable mechanical documentation.

Key Responsibilities

• Drafting & Modeling: Create fabrication drawings for tanks, vessels, piping, and equipment assemblies.
• Layout Preparation: Develop general arrangement (GA) drawings, piping layouts, and skid designs.
• Documentation: Generate BOMs, welding details, material specifications, and revision records.
• Standards Compliance: Apply GD&T, ISO, and pressure vessel codes.
• Collaboration: Work with process engineers, proposal engineers, and manufacturing teams.
• Revision Control: Update drawings based on engineering changes or client feedback.
• Manufacturing Support: Provide shop-floor drawings and assist in resolving drawing-related queries.

Education & Background

• Qualification: Diploma/ITI in Mechanical Drafting or Mechanical Engineering.
• Experience: 2–5 years drafting for water treatment or process equipment industries.
• Certifications: CAD proficiency (AutoCAD, SolidWorks, CATIA, Creo) and GD&T training.

Essential Skills

Technical: CAD drafting, piping layouts, pressure vessel drawings

Analytical: Dimensional accuracy, tolerance analysis

Documentation: BOMs, GA drawings, compliance records

Collaboration: Coordination with engineers, vendors, and shop floor

Software: AutoCAD, SolidWorks, CATIA, Creo, Plant 3D

Challenges & Considerations

• Handling complex piping and equipment layouts under space constraints.
• Ensuring corrosion-resistant materials are correctly specified for water treatment environments.
• Adapting to frequent design changes during tender and execution phases.
• Maintaining accuracy and compliance with international standards.
