WTRM 202: Beginning Water, Wastewater, Distribution Math

This text examines advanced study of mathematical principles related to pump hydraulics: horsepower, flow rates, pump curves, chemical dosages, detention time, filtration and backwash rates, CT calculations and various utility management analyses related to budget preparations, water rate structures, and demand design forecasting. Focuses on mathematical computations within the expected range of knowledge on the State of California Water Resources Control Board exams.
