Precision System

Precision Systems, based in Calumet City, Illinois, has supplied water and wastewater equipment for over 50 years. The company designs and manufactures packaged pumping systems, valve assemblies, chemical feed systems, standby power units, and odor control equipment primarily for the municipal water and wastewater market, with additional capability to serve industrial and bulk water applications. Their product lines carry the distinctive Pac naming convention — Power Pac for emergency standby generator enclosures, Valve Pac for pre-engineered valve package assemblies, Twin Pac for dual-pump configurations, and Hydro Pac for hydro-pneumatic pressure systems. The wastewater portfolio includes vacuum-primed and submersible pumping stations, each delivered as a factory-assembled package with controls and ancillary equipment. Precision Systems also offers wet well aeration systems, sampling equipment enclosures, and emergency bypass connections as standard accessories. The company emphasizes customization, producing each system to client specifications rather than catalog configurations, and provides engineering tools such as generator sizing and pump station sizing calculators through its representative portal. Services extend beyond manufacturing to include customer training programs, on-site product support, and 360-degree virtual tours of completed installations.
