When it comes to drainage solutions in aggressive environments, material selection makes all the difference. Traditional galvanized corrugated metal pipe often struggles to withstand the corrosive effects of saltwater, brackish water, and hypersaline soils. That’s where Corrugated Aluminum Alloy Pipe (CAP) stands apart.

America’s Wastewater Infrastructure is currently rated at a D+, according to the 2025 ASCE Report Card for America’s Infrastructure. The Wastewater category includes both piping for the collection systems and the wastewater treatment plants the piping leads to. The collection system alone experiences 3.3 failures per 100 miles of pipe every year, putting pressure on maintenance teams to identify suspect pipes for either complete replacement or pipeline rehabilitation. This article will focus on the design and construction considerations necessary when a pipeline owner determines they will be rehabilitating an existing pipe.

Unlike circular pipes, arch-shaped culverts present a unique challenge when it comes to structural rehabilitation. Their non-round geometry and sometimes integrated parapet walls mean that standard sliplining methods don't always apply. However, just because a culvert isn’t round doesn't mean it can’t be effectively relined.

Why have a preconstruction meeting for pipe? Engineers have been designing various types of pipe for hundreds of years, while contractors have been installing it for hundreds of years. What needs to be discussed?  It’s fair to say that all stake holders (owner, engineer, contractor and manufacturer) want a successful project. Taking the time a week prior to installation to cover key items will save time, and money, by recognizing and mitigating any issues before they arise.

Contech and US Pipe team up to delivered an educational webinar designed to address the challenges and opportunities in municipal water and wastewater infrastructure.

Contech’s QuikJoint™ can help to provide a fast, efficient, and cost-effective way to facilitate post installation joint testing of large diameter DuroMaxx® SRPE pipe.

There are limited options for verifying a large to ultra-large diameter sewer pipe. You can do visual inspections, low-pressure air using isolation rigs & bladders or hydrostatic methods. These are either not effective or expensive and time consuming. A new method has been introduced to the industry via Contech Engineered Solutions’ (Contech) DuroMaxx® Steel Reinforced Polyethylene (SRPE) Pipe and the QuikJoint® Ultra High-Performance Technology.

We are often asked, “How much does a reline project cost?” While this is a straightforward question, the answer depends on multiple factors. Before attempting to provide a cost estimate, it’s important to consider the broader perspective—particularly in comparison to traditional open-cut replacement.
