Rovanco has been custom designing and manufacturing prefabricated manholes since 1982!
Rovanco prefabricated steel manholes can play an important role in your underground heat distribution system.
Rovanco Prefabricated Manholes can be installed in one day!
Allow you to accelerate the placement of manholes to get streets open in three days or less.
The average construction time for field built concrete manholes is 2-3 weeks plus time to pipe and finish the inside. Using precast sections you might save 1 week.
Since the Rovanco manholes are custom-made you can choose what thickness of the base and top you want.
Rovanco is currently building 7 manholes rated for fire trucks filled with 40,000 pounds of water. So Rovanco can build manholes of any size up to 45' long, 10 foot wide, and 10 foot high. H-20 loading available.
