## Wastewater Treatment Operations: Math Concepts and Calculations

Wastewater Treatment Operations: Math Concepts and Calculations covers computations commonly used in wastewater treatment plant operations. This manual presents math operations that progressively advance to higher, more practical applications of mathematical calculationsâ€”that is, the math operations that operators at the highest level of licensure would be expected to know how to perform.

## Water and Wastewater Calculations Manual

This manual presents the basic mathematical principles and concepts relating to water/wastewater engineering. To the extent possible, examples rely on practical field data and regulatory requirements have been integrated into the environmental design process. Each of the calculations provided is solved step-by-step in a streamlined manner that is intended to facilitate understanding. Examples (step-by-step solutions) range from calculations commonly used by operators to more complicated calculations required for research or design.

## Water Audit Data Grading Sheets

These tables allow you to analyze the data grades for each input in AWWA’s Water Audit Software.

## Water Loss Control Goal Setting

If a water utility is going to begin a water loss control program, it should clearly define and understand its goals for the program. This document provides information about setting goals to define water loss control program expectations.

## Water Loss Reduction Toolbox

Table listing types of loss, tools to help reduce the loss, and a cost range.
