ABSTRACT
Calculations, calculations, calculations, and more calculations! Indeed, we can’t get away from them-not in water/wastewater treatment and collection/distribution operations, not in licensure certification examinations, and not in real life. Basic calculations are a fact of life that water/wastewater maintenance operators soon learn and, it is hoped, learn well enough to use as required to operate a water/wastewater facility correctly. Basic calculations used frequently in water hydraulic and pumping applications are discussed in the following sections. In addition to the basic calculations, key definitions and applicable illustrations are provided. Also covered, at a higher technical level, are calculations for pump specific speed and suction specific speed, affinity formulas, and other advanced calculations.
