Preventative Maintenance Program
Multi-Point Inspection & Service

The JWC Preventative Maintenance Program is designed to protect you from unexpected downtime and extend the life of your equipment.

It is no secret that preventative maintenance is a must for harsh duty equipment. But that routine maintenance gets tougher to do when you consider the challenges facing our wastewater operators today–fewer staff members, less equipment standardization and an aging infrastructure. That’s where JWC’s Preventative Maintenance Program comes in.

Our factory service technicians will travel to your sites to assess the equipment’s overall performance, perform routine maintenance and provide a detailed report with recommendations to improve operations and extend equipment life. It is also an excellent time to train your staff on the equipment in your facilities.
