35 AUGUST 2024 WorldWide Drilling Resource® Fiberglass Conduit for Wastewater Applications Adapted from Information by Champion Fiberglass Few industrial environments are more caustic or damp than wastewater treatment facilities, and corrosion resistance is key when specifying conduit for wastewater and sewer system projects. Harsh chemicals, extreme temperatures, and aging infrastructure requires strong, durable conduit systems. More than 14,000 wastewater treatment plants provide critical infrastructure required to maintain public health in the U.S. There are many options available to project managers and engineers, so it’s important to consider the location and environment specific to each project when selecting conduit. Understanding environmental contaminants and chemical processing is critical because bleach, polymer wastewater sludge, liquid oxygen, and waste activated sludge can all threaten the integrity of electrical conduit systems. Among the types of conduits in environmental engineering, fiberglass conduit offers a cost-effective, long-term solution. Fiberglass conduit is significantly lighter in weight than traditional conduit material, and is often preferred for utilities, commercial, and industrial applications requiring direct burial and encased burial belowground installations, because it is resistant to temperature, moisture, and corrosion. It is also nontoxic, making it an environmentally friendly option, and chemically inert, which contributes to its longevity. Its unthreaded joints make it easy to install, and its low coefficient of friction eliminates the risk of burn through for long cable pulls. Here are some key factors to consider when picking the right conduit for the job: j The protective qualities of the substrate. j Ease of installation and associated cost. j Long-term costs associated with durability and project lifespan. j Up-front materials and labor cost. j Availability and lead times. It’s important to consider a variety of attributes affecting the lifespan of your installation, not limited to the conduit’s level of corrosion, temperature range, and impact resistance. WTR
