JCW Sewer Rehabilitation and Repair Projects

Johnson County Wastewater (JCW) collects and cleans more than 18 billion gallons of wastewater annually for more than 500,000 customers in Kansas’ most populous county. Its system includes six treatment facilities and 2,300 miles of sewer mains, 28 miles of low-pressure sewers, 42 miles of force mains and 31 pump stations. 

For more than a decade, TREKK has helped JCW maintain and improve the reliability, efficiency and quality of its wastewater collection system on more than 90 on-call projects. These projects play a critical role in supporting JCW’s Integrated Plan to address aging infrastructure, community growth and redevelopment, wet-weather management and operations and maintenance initiatives. 

TREKK’s work includes existing infrastructure sanitary sewer collection system rehabilitation, repair and improvement projects; new development gravity sewer projects; low-pressure sewer projects; and on-call plan review and construction inspection services. We provide everything from field investigations and design services, to asset management and GIS to construction engineering and inspection, meeting JCW’s holistic needs. 

Our field services experts have pioneered new approaches to safely and efficiently conduct field inspections, and we use innovative tools that streamline data collection and delivery. Using our TREKK360 camera, we have standardized JCW manhole inspections and completed air release valve inspections, providing a more comprehensive inspection while keeping our team and the public safe. Our in-house construction engineering and inspection team helps oversee the construction of manhole and sewer line improvement projects.  

We have completed multiple flow monitoring studies, providing installation, on-going maintenance and data delivery for dozens of meter sites to support various capacity enhancement and modeling projects. Our asset management and GIS team performs data management and analysis and supports updates to JCW’s computerized maintenance management system.  

Over the years, TREKK has helped JCW refine and implement its private I/I program, JoCo Inflow, to remove private connections to JCW’s system. We also assist with the Backup Prevention Program, which addresses sanitary sewer backups into basements during and after heavy rain events.
