sewage ejection pump?

In San Antonio we don’t have many basements so I haven’t ran a cross a lot of systems that require a pump for drainage plumbing. This is a 2011 home that has a pump to pump sewage back to the street level as this home sits pretty low on a hill. I’m assuming this would be called a sewage ejection pump. I would love to read any I could or find out life expectancies of such systems so I could help educate my clients. If anyone could point me to any good articles it would be appreciated
