Fiberglass Grinder Manholes are a unique solution to the problem of mounting sewage grinders below grade.
The all-fiberglass construction means the unit has high-strength, is watertight, and is corrosion resistant…all at about 1/10th the weight of concrete with essentially no maintenance. Installing a Fiberglass Grinder manhole is easy and line downtime is minimal. Dig a hole, drop it in, and you are done!
The grinder is recessed into a floor cavity and held in place by either in-channel stainless steel guides or full-height factory guide frames depending upon your needs.
Each Fiberglass Grinder Manhole come standard with:
- OHSA-compliant fiberglass ladder with non-slip ladder rungs
- Integral fiberglass grinder channel with non-slip gritted bench / shoulder
- Recessed, removable fiberglass grating (over the grinder channel)
- Stainless steel cabling hook (for spare power / control cabling)
- Manhole thru-wall coupling (for power / controls cabling)
- Inlet / outlet piping with flexible couplings for quick pipeline connection
Openness
Fiberglass Grinder Manholes can designed to accommodate open channel grinders from the leading manufacturers, including:
