Types of Fiberglass Manholes

To make the most of your operation, TRACOM offers six main types of fiberglass manholes. Choose one of the following that best meets your needs:

Wet Well Manholes

Tracom Wet Wells are designed using the latest fiberglass technology to ensure maximize the time between rehabilitations.

Splitter Manholes

When designing a manhole system where you need to divert a portion of the wastewater flow from one existing main to a new one, consider TRACOM’s splitter manhole options.

Mag Meter Manholes

To measure closed pipe flows, Tracom has magnetic flow meters integrated with our packaged fiberglass manholes.

Energy Absorbing Manholes

Fiberglass energy-absorbing manholes are used in instances where site conditions prevent a sub-critical and tranquil flow.

Grinder Manholes

Some of the most important wastewater management tools are grinders, as they prevent pump clogs and serious damage caused by large particles.
