Precast Concrete Manholes

Precast concrete manholes play a crucial role in contemporary sewer systems. When designed and installed correctly, they deliver exceptional watertight performance, outperforming alternative materials and methods. These manholes can be installed at various depths, as lateral forces evenly distribute around the perimeter, placing the structure in optimal compression—ideal for concrete.

Manufactured in controlled conditions, precast concrete manhole sections maintain consistent quality and uniformity, ensuring durability and reliability in wastewater management applications. Their efficiency and effectiveness make them a preferred choice in infrastructure projects.

Applications

Precast manholes are a vital element of wastewater and stormwater systems, offering essential access to underground conveyance infrastructures.

Sanitary Sewer Systems

Wastewater manholes are a critical part of sewer systems, offering access for maintenance and inspection of underground drainage structures.

Stormwater Collection

Precast manholes act as collection points for stormwater runoff from streets, parking lots, and other impermeable surfaces, channeling the water into the stormwater management system.

Wastewater or Stormwater Treatment

Precast manholes can incorporate sedimentation or filtration features to filter out debris, sediment, or pollutants from the flow before it is released into water bodies or infiltration systems.

Municipal Infrastructure

Manholes are essential in various municipal infrastructure systems, such as water treatment facilities, storage tanks, treatment plants, and pump stations.

Flow Control

Manholes can incorporate flow control devices, like weirs or orifices, to manage stormwater flow and help prevent flooding or erosion downstream.

Pipe Transitions

Manholes enable adjustments in pipe size, direction, or slope, ensuring efficient stormwater conveyance throughout the drainage system.

Inlet & Outlet Structures

Manholes can function as inlet or outlet structures for stormwater detention or retention ponds, managing water flow into and out of these facilities.
