When it comes to upgrading your town’s infrastructure, choosing the right manhole cover and frame can make a major difference. Traditional cast iron systems are heavy, prone to corrosion, and contribute to infiltration and inflow (I&I). SuperCover’s advanced composite technology solves these issues—boosting long-term performance while reducing maintenance costs. Here's why SuperCovers are the modern solution your municipality needs.
Why SuperCovers Are the Best Choice for Your Town's Sewer System
Why SuperCovers Are the Best Choice for Your Town's Sewer System

Engineered to Eliminate Inflow and Infiltration (I&I)
SuperCover’s proprietary SureSeal™ system features sealed manhole covers and a double-gasket design, preventing rainwater and debris from entering the sewer system. This reduces the risk of sanitary sewer overflows (SSOs) and keeps treatment costs down.

Lightweight Yet Heavy-Duty
Unlike a traditional cast iron manhole cover, SuperCovers are made from composite material that’s both strong and easy to handle. Crews can remove them without a manhole hook, reducing injury risk and streamlining routine inspections.

Built-In Safety and Alignment Features
Each manhole frame includes anti-rotating designs and self-aligning guides, helping crews install covers properly every time. These features reduce long-term wear and ensure the cover fits flush—key for safety and durability.

Long-Term Value with Third-Party Approved Performance
SuperCovers are approved by multiple third-party organizations, including the Texas Department of Transportation. They come with a 5-year warranty, offer a bolted inflow dish, and are built to outperform traditional sewer drain cover options.
Upgrade Your Infrastructure with Confidence
Whether you're a city planner or a municipal operator, SuperCovers provide unmatched performance in modern infrastructure. Say goodbye to outdated sewer hole cover systems and upgrade to a smarter, safer solution—engineered in Texas, trusted nationwide.
