Challenge
The 54-inch reinforced concrete pipe (RCP) at the Pierce-Burch Water Treatment Plant was exhibiting critical joint spalling, substantial joint offsets, extensive calcium deposits, and significant debris accumulation. These issues were compounded by the restricted 4.5-foot internal diameter, challenging access limitations, complex dewatering requirements, and the necessity to complete all rehabilitation work within a non-negotiable 14-day shutdown window to avoid service interruptions.
Results
MIC utilized OBIC’s spray-applied polyurea lining system to complete the full rehabilitation of 420 linear feet of 54-inch RCP in just 6 days well within the allotted shutdown window. This intervention reinforced the structural integrity of the pipeline, restored optimal flow capacity, and provided long-term protection against corrosion and chemical attack. With over 130 buckets of debris removed and service life significantly extended, the City of Arlington expressed strong satisfaction with the outcome and has scheduled additional phases of rehabilitation.

About Midwest Infrastructure Coatings
Midwest Infrastructure Coatings (MIC) is a premier infrastructure rehabilitation firm specializing in high performance protection for municipal and industrial assets. As an OBIC-certified installer, MIC combines advanced polymer technology with expert craftsmanship to deliver long-term solutions for aging wastewater, potable water, and industrial systems.
The Challenge
The Pierce-Burch Water Treatment Plant faced significant operational risk due to advanced structural deterioration within a critical 54-inch reinforced concrete pipe. Severe joint spalling, joint misalignment, heavy calcium buildup, and substantial debris accumulation threatened both water flow and system integrity. The challenges were magnified by the limited access provided by the pipe’s 4.5-foot diameter, the need for specialized dewatering, and a strict 14-day shutdown window imposed to maintain service continuity for the community.
The Solution
To address these acute challenges, Midwest Infrastructure Coatings (MIC), an OBIC-certified installer, evaluated advanced rehabilitation technologies that could deliver rapid, durable, and trenchless restoration with minimal disruption. After considering various traditional and trenchless repair methods, MIC selected OBIC’s spray-applied polyurea lining system for its proven performance in chemical resistance, structural reinforcement, and rapid cure times, which allowed for same-day return to service. This decision was validated by the City of Arlington’s response: "The City of Arlington expressed strong satisfaction with the project outcome and has planned additional rehabilitation work for future phases." MIC deployed the OBIC system to efficiently remove over 130 buckets of accumulated debris, prepare the existing pipe substrate, and apply a seamless polyurea lining that addressed both corrosion and structural issues within an accelerated timeline.
The Results
Leveraging OBIC’s innovative polyurea technology, MIC completed the rehabilitation of 420 linear feet of 54-inch RCP in just 6 days far exceeding expectations within the demanding 14-day shutdown window. The project resulted in restored flow capacity, enhanced structural longevity, and significant reduction in future maintenance requirements. Key metrics include removal of over 130 buckets of debris, rapid project turnaround, and the elimination of the need for disruptive full pipe replacement. The City’s endorsement and commitment to future project phases underscore the solution’s effectiveness and value to municipal water infrastructure management.
