Wastewater isn’t rocket science. It’s just harder and significantly more important. Every engineering discipline makes fun of the civils, but the fact is none of us are half as critical to modern life as them. Every benefit any of us claim rests on their backs. The flow of electricity is a civil engineering feat, the flow of water to and from our homes, businesses, and farms is a civil engineering feat (and critical to health), as is our transportation networks, our entire constructed environment, and even crazy and weird shit like controlling the location of critical rivers.
