• Manholes are manufactured as a total flow monitoring solution. The metering manholes may be supplied with any type of flume or flow measurement weir integral to the structure.
• The strong one-piece design assures that the manhole will never leak, eliminating infiltration at the site. Fiberglass manholes weigh only a fraction of the weight of pre-cast manholes, allowing for quick and easy installation with less equipment and labor.
• Fiberglass construction ensures that corrosive liquids and gases will not cause structural problems, enabling the manhole to serve a long, maintenance-free life. Their compact and lightweight design makes them ideal for both industrial and municipal applications.
• Manholes are offered in two sizes, 48 -inch or 60-inch diameters. Each size can be configured with either a hinged fiberglass cover or H-2O adapter cover for installation in traffic areas. Both styles are completely leak free and meet equivalent load ratings as those of the manhole body.
