With over 40 years of industry experience, Pen Manufacturing supports wastewater and sewage treatment companies that require a wide range of parts, certified welding, and precision sheet metal work—all handled in-house.  To meet the strict standards of this sector, Pen hires only top-tier talent. Welder applicants must already hold required certifications and bring a minimum of 10–15 years of experience. Fewer than 5–10% of candidates are accepted, ensuring only the most qualified professionals work on customer projects.  This commitment to expertise and certification allows Pen Manufacturing to consistently deliver dependable, high-quality components for critical wastewater systems.
