Sewer Manholes

Precast sanitary manholes provide both access and transition points for your sanitary sewer system.  Typical configurations consist of a base unit, risers and a top section.

  • SewerAvailable in sizes from 48” to 144” diameter.
  • Precast Inverts Available
  • Standard Cones and Custom Tops Available
  • Booted Connections
  • Offset gasketed joints for select diameters
  • Doghouse risers (for straddling an existing line)
  • Anti-Flotation Collars
  • Protective Coatings, Liners or Admixtures

Sanitary sewer lines typically require a flexible resilient connector between the specified pipe and manhole.  These connectors can either be cast into your manhole or added secondarily through a cored hole and flexible connector.  Foley Products Company keeps ample inventory of solid manhole bases to allow for quick core, boot and delivery of your precast sanitary manhole.
