Openchannelflow fiberglass Diversion Manholes help operators control, direct, and distribute below-grade non-full pipe flows.
Diversion Manholes are available in multiple configurations, including:
- Interior drops
- Y-channels
- J-bends
Diversion Manholes allow for drop-in-place installation and can be provided with gated channels to direct flow to different downstream locations.
Like our other fiberglass manholes, Openchannelflow Diversion Manholes are single-piece, watertight, and corrosion-resistant.
When Y-channels or J-bends are provided, fiberglass benching is included around them. The benching eliminates the need to pour concrete benching in the manhole and has a molded-in non-slip diamond plate pattern. The diamond plate doesn't wear or blind like gritted surfaces and is easy to maintain.
A variety of top styles are available with Openchannelflow Diversion Manholes, including:
- Domed Fiberglass (for non-vehicle / traffic areas)
- Aluminum Covers (for pedestrian traffic areas)
- H-20 Traffic Reducers (for use with standard grade rings, frames, and covers)
- Open Top (for custom applications where the manhole top needs to be open or provided with a fiberglass grating)
Openchannelflow Diversion Manholes are available in sizes from 48 to 96-inches [1.22 to 2.44 m] in diameter and depths up to 35-feet [10.7 m].
As the size / complexity of the diversion system increases, larger diameter Diversion Manholes are necessary.
