Manhole Systems

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.
