Charter Machine Company is a U.S.-based manufacturer and solutions provider specializing in wastewater and sludge processing equipment for municipal, industrial, agricultural, and food processing applications.
With decades of experience supporting operators and engineers, Charter Machine Company designs and delivers equipment and systems focused on reliability, efficiency, and long‑term performance across the full sludge handling lifecycle—from thickening and dewatering to drying, conveyance, and post‑treatment.
Founded in 1968 as GEC Incorporated, Charter Machine Company began as a full‑service machine shop capable of both large‑ and small‑run precision machining. By 1974, the company expanded into manufacturing its own equipment with the introduction of the GEC Turret Rewinder, serving the printing industry.
Over time, the company diversified beyond printing to support a wide range of industries, establishing a reputation for precision manufacturing, quality workmanship, and technical expertise. As our capabilities expanded, so did our focus - leading to the development of advanced solutions for sludge processing and wastewater treatment under our current name, Charter Machine Company.
Charter Machine Company’s sludge processing capabilities are built on decades of manufacturing experience supporting liquid‑solid separation equipment. Long before entering the market under its own name, Charter played a direct role in the fabrication and assembly of belt filter press components - including frames and rollers - working from original Roediger drawings and contributing to the construction of presses installed at biosolids treatment facilities nationwide.
When changes in the Pittsburgh manufacturing landscape created an opportunity for expansion, Charter Machine Company transitioned from component supplier to full system provider - leveraging proven Roediger technology while advancing design, fabrication, and service capabilities under the Charter Machine Company name.
Biosolid Treatment facilities have relied on Roediger equipment for decades due to its durability, performance, and robust design. Having directly participated in the manufacture, support, and continuation of the former Roediger Pittsburgh equipment line, Charter Machine Company has become a recognized and trusted name in the dewatering industry.
Today, Charter Machine Company continues to support existing Roediger installations while expanding the product line to meet evolving sludge processing needs, ensuring continuity for long‑term operators and confidence for new system deployments.
Charter Machine Company has long supplied service and replacement parts to Roediger customers and has served as a trusted partner for equipment rebuilds, upgrades, and new projects. Integrating the Roediger equipment line into Charter’s in‑house manufacturing operations aligned naturally with the company’s established capabilities in precision machining and heavy equipment fabrication.
To support this growth, Charter Machine Company expanded its team to include experienced engineering, service, and sales professionals with deep expertise in dewatering applications. This combination of technical knowledge, fabrication control, and field experience has strengthened the company’s reputation for quality workmanship, reliability, and customer service.
