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.

• One day to excavate and set the manhole
• One day to hook up the pipes entering and leaving the manhole
  
• One day to touch-up coating, apply anodes and backfill.

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.

• Round
• Square
  
• Rectangular
  
• Oblong
