Solving Inflow and Infiltration Issues with Trenchless Manhole Rehabilitation

Inflow and infiltration (I&I) are common problems for many municipal sewer systems. When excess water enters the system through cracked manholes, it can overload pipes and treatment plants. Addressing I&I is essential to maintain sewer capacity, reduce treatment costs, and prevent overflows. One effective way to tackle this problem is through trenchless manhole rehabilitation, including CIPP pipe lining in Bedford, IN. Read on as SLB Pipe Solutions discusses further.

What Causes Inflow and Infiltration?

Inflow happens when rainwater directly enters the sewer system through manhole covers, broken frames, or open connections. Infiltration occurs when groundwater seeps in through cracks, gaps, or deteriorated walls. Over time, older manholes made of brick, concrete, or mortar often develop leaks due to soil movement, root intrusion, or corrosion. Left unaddressed, I&I can overwhelm pipes and treatment facilities, leading to unnecessary expenses and environmental concerns.

How Trenchless Manhole Rehab Works

Trenchless manhole rehabilitation involves repairing manholes without extensive digging. Methods like spray-applied liners, cured-in-place pipe lining, or chemical grouting can restore the manhole’s structural integrity and watertightness from the inside. These techniques seal cracks and joints, filling voids and gaps that allow unwanted water to enter. Trenchless rehab is faster than excavation and minimizes disruption to streets and traffic.

Benefits for Municipal Sewer Systems

Rehabilitating manholes with trenchless methods reduces I&I at a lower cost than full replacements. Cities and utilities can extend the lifespan of their existing infrastructure while avoiding the mess and expense of digging. Trenchless manhole or sewer pipe lining also lowers maintenance costs and reduces the risk of overflows during heavy rain. The process is efficient, safe, and can be done with minimal downtime.
