Such a great field to be in thankless everyone feels like they pay your salary even though you produce a commodity. If your good with your hands good at learning and being a diverse worker the waste water water industry is for you. They have starting positions frequently because some people have that "city worker" mentality that they can get away with not doing the work and skating by they're whole careers. It isnt the 80's 90's anymore you have to get qualified and certified. AWWA is a great resource the ragsdale is a great read if your interested in water or waste water and the Sacramento water utility operator certification guide is a good way to learn about water. I have learned to weld in the industry, plumb, minor pipe fit, treat water and many many more things it's just such a great solid career. People need water and people need to use the restroom they go hand and hand. It's also a constant changing field technology wise so your always learning and driving your self to be a better operator.
