Inland Water Pollution Control
Inland Water Pollution Control (IWPC) is a Detroit-based infrastructure services firm with more than 50 years of experience supporting Michigan’s municipal water and wastewater systems. Founded in 1973, IWPC has grown alongside the region’s infrastructure by adapting its services, technologies, and delivery methods to meet the evolving needs of public agencies, utilities, and engineering partners.
Originally focused on sanitary sewer solutions, IWPC has expanded into a full-service provider offering engineering support, design assistance, and a comprehensive portfolio of trenchless rehabilitation technologies. Today, IWPC helps owners address aging infrastructure challenges with cost-effective, minimally disruptive solutions that extend asset life, reduce risk, and improve system performance.
With deep local knowledge and a long history of collaboration with Michigan municipalities, IWPC delivers practical, constructible solutions that align with regulatory requirements, budget constraints, and long-term capital planning goals. Over five decades of continuous operation, IWPC has successfully delivered thousands of linear feet of rehabilitation work across a wide range of pipe sizes, materials, and site conditions. Our services have expanded to include specialized trenchless methods designed to address structural deterioration, infiltration and inflow (I&I), corrosion, and access limitations in both sanitary and storm systems.
IWPC’s crews, engineers, and project managers bring hands-on field experience and a disciplined approach to quality, safety, and schedule control. Our in-house capabilities allow us to self-perform critical work elements, ensuring consistency from design through installation and closeout.
Single Source Accountability & Industry Dedication
IWPC is committed to Single Source Accountability for Cure in Place Pipe, providing clients with a streamlined delivery model that reduces interfaces, minimizes risk, and improves overall project outcomes. From early planning and design support through construction and post-installation documentation, IWPC manages the full lifecycle of CIPP trenchless rehabilitation projects.
By maintaining direct control over labor, equipment, installation procedures, and quality assurance, IWPC delivers:
- Improved schedule reliability
- Enhanced quality control and consistency
- Faster issue resolution in the field

This integrated approach allows IWPC to serve as a trusted partner rather than just a contractor, especially on complex or high-risk rehabilitation programs.
Markets & Solutions
Projects
Wayne County
This project included tasks authorized under Phase 2C & 3C of the larger Wayne County – Rouge Valley Sewage Disposal System Rehabilitation Project along the Middle Rouge River. The project scope involved inspections, widespread cleaning and grouting, CIPP lining, geopolymer lining, interceptor chamber rehabilitations, and new sanitary structure installations.
- Thorough structure & sewer pipe inspections and cleanings. Documented current conditions and debris removal through CCTV submittals. Sewer cleaning utilizing manned entry methods and jetter-truck equipment.
- Widespread grouting throughout the system to stop infiltrations of ground and river water into the sewage disposal system which was overwhelming the WWTS.
- Rehabilitation of extensively degraded sewer pipe segments through a combination of Cure-In-Place-Pipe (CIPP) and Geopolymer SAPL lining.
- Extensive manhole deconstructions and reconstructions to accommodate lining operations and to remove debris (many reconstruct fully to the spring line).
- Design of multiple traffic control plans for both vehicular and pedestrian control throughout the highly utilized Wayne County Parks areas along Edward Hines Drive.
- Design and install multiple flow diversion and bypass pumping plans.
- Created as-built drawings for assets that the client did not have on record.
- Installation of new sanitary structures into existing sewer lines.
- Emergency repair and lining of lateral sewer under the Middle Rouge River
- Manhole structure lining and bench work.
- Concrete and HMA restorations.
- Lengths examined & repaired:
- 21,000 LF of large diameter rehabilitation/Lining
- 86,000 LF of cleaning and CCTV inspections work.
- 1M+ lbs. of geopolymer spray lining work.
