Energy Absorbing Manholes

Energy Absorbing Manholes are used to slow the flow of water through a below-grade pipe system, usually (but not always) so that downstream flow meters work properly. Each unit includes a fiberglass manhole tube, energy-absorbing structure, mounting flange, cover, and base.
Especially when paired with Packaged Metering Manholes (PMMs), fiberglass Energy Absorbing Manholes (EAMs) are a cost-effective and efficient solution. In addition to being watertight and corrosion resistant:
- EAMs avoid costly line excavations or replacements.
- They also allow you to save on labor and machinery costs when you install a PMM at the same time.
- Factory integration / single-source responsibility.
- Installation of EAMs is as simple as dig it, drop it, done.
EAMs are available in variety of sizes, including diameters from 48- to 96-inches [1.22 to 2.44 m] and depths up to 35-feet [10.7 m].
Depending on the depth of a manhole, seeing inside can be a challenge. All Openchannelflow EAM tubes are smooth inside and a light tan color to help maximize visibility.
While most EAMs ship as a single piece, those of unusual depth or that integrate large flow-conditioning devices might ship in two or more pieces.
Suit your site needs by selecting from a variety of top styles:
- Domed Fiberglass Tops, the most popular choice, is commonly used for grassy non-traffic areas.
- Aluminum Covers, which are typically used for pedestrian walkways and non-traffic or low-profile installations.
- H-20 Traffic Reducers for areas with traffic, like parking lots, loading docks, and warehouse floors.
- Open Tops for sites already covered with a shelter or other access-restriction measures.
Make the most of EAMs with a variety of accessories that help with air circulation, depth adjustments, equipment or mounting panels, storage, work surfaces, and more.
