Openchannelflow - Fiberglass Diversion Manholes

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.
