Can you name two or three different types of water pumps?
In-plant pump stations are a key component of any water treatment facility, giving the ability to move large quantities of water in a quick fashion. Your interview asks this question in hopes that you have some familiarity with the different types of water pumps that are used in the water treatment process.
"I have direct hands-on experience with submersible pumps used around the home and rotary displacement pumps used in hydraulic systems. Having a strong background in mechanics, I would come to your team as a water treatment operator who is excited to learn the ins and outs of the positive displacement pumps you use here. Can you elaborate on any other types of pumps that this facility uses the most?"
This is a question that you can certainly answer briefly and factually. Take a moment to explain which water pumps you are most experienced in working with if you have firsthand experience. If you need to, be sure to familiarize yourself with the centrifugal, progressive cavity, and positive displacement water pumps, as they are the most commonly used in water treatment processes. If you want, you can follow up with a question for the interviewer on this subject as well.

I only know of two basic types of water pumps: centrifugal and positive displacement. Both models are designed to move water from one place to another continuously.
