Sommario/riassunto |
|
To properly operate a waterworks or wastewater treatment plant and to pass the examination for a waterworks/wastewater operator's license, it is necessary to know how to perform certain calculations. All operators, at all levels of licensure, need a basic understanding of arithmetic and problem-solving techniques to solve the problems they typically |
|
|
|
|
|
|
|
|
|
|
encounter in the workplace. |
