# Force Main — Utility Construction Glossary

A pressurized pipeline that moves wastewater or sewage from a lower to a higher elevation, typically using pumps in lift stations when gravity flow is not feasible.

## Frequently asked questions

### How do force mains differ from gravity sewers?

Force mains use pressure created by pumps to move wastewater, while gravity sewers rely on natural slope for flow. Force mains typically require less depth but more maintenance.

### What materials are used for force mains?

Common materials include PVC, HDPE, and ductile iron pipe, chosen based on pressure requirements, soil conditions, and chemical resistance needs.
