Influent
Influent refers to the incoming water or wastewater that needs to be treated at a treatment facility. Think of it as the "before" water that enters a plant, whether it's dirty water from homes and businesses going to a wastewater plant, or raw water from rivers and lakes entering a drinking water plant. When you see this term in resumes, it usually indicates experience with managing, testing, or monitoring incoming water quality and flow. It's a basic but important concept in water treatment operations, similar to how a doctor needs to understand a patient's condition before treatment.
Examples in Resumes
