Every gallon of drinking water that reaches a faucet, and every gallon of wastewater that leaves a home, is moved by a pump at some point in its journey. Whether you staff a water treatment plant, run a distribution system, maintain sewer lift stations, or operate a wastewater treatment facility, you will work with pumps every single day of your career — and understanding how they work, why they fail, and how to keep them running safely is one of the most universally valuable skills any water professional can develop. This guide covers the fundamentals that apply no matter which of the four disciplines you work in.
Why Pumps Matter in Water and Wastewater Systems
Gravity alone cannot move water and wastewater everywhere it needs to go. Pumps add mechanical energy (head) to a fluid so it can overcome elevation changes, friction losses in pipe, and the pressure required at the point o
