What is Handhole?
A handhole is a small access opening built into underground systems to allow inspection, maintenance, and routing of electrical conductors or irrigation lines.
Definition
Purpose
Running conduit or irrigation pipe without handholes is a short-term decision that catches up with you fast. A long conduit or irrigation run is difficult to access when repairs are needed, or a conductor has to be pulled. Handholes provide those access points, helping reduce pulling tension and giving crews a spot to work without digging up the line.
Examples of Use
- Electrical Systems: Installed along conduit runs to give crews access for pulling, redirecting, or splicing conductors without digging up the ground.
- Landscape Irrigation: Sit over valve clusters and pipe joints to allow crews to access them easily, especially for seasonal adjustments or repairs.
- Telecommunications: Used to manage cable slack, make connections, and access underground lines along communication routes.
- Drainage: Provide access for clearing blockages and checking pipes without having to excavate the entire line.

Notes
- Lid ratings matter. A handhole in a parking lot needs a cover rated for vehicle loads; one tucked into a planting bed does not.
- Spacing them correctly along a conduit run keeps pulling tension manageable and protects the electrical conductors from damage during installation.
- The interior has to be large enough to accommodate the minimum bend radius of the cables or pipes passing through.
