The Complete Guide to Becoming A Water/Wastewater Engineer

Chapter 1: What Does a Water/Wastewater Engineer Actually Do?

Let's cut through the job-title fog. When someone says "water/wastewater engineer," they are not talking about a single job. They are describing a broad role that covers the planning, design, construction, and operation of the systems that bring clean water into our homes and businesses, and that take the dirty water away. It's a job that sits at the intersection of civil engineering, environmental science, chemistry, and public policy. To understand what you would actually do all day, you have to break this down into the core responsibilities.

The first thing to understand is that your primary product is a piece of infrastructure that works reliably. You are not designing a smartphone app or a flashy bridge. You are designing a mile of pipe that has to carry a certain amount of flow at a certain pressure, without leaking, for the next fifty years. Or you are designing a treatment process that takes river water and, through a series of physical and chemical steps, makes it safe enough to drink. Or you are designing a system that takes the wastewater from a city's toilets, sinks, and factories and cleans it enough to release back into a river without killing the fish.

There is a fundamental split in this field, and you will likely lean one way or the other. The "water" side focuses on the supply side: sourcing water from rivers, lakes, or underground aquifers, treating it to meet drinking water
