Which is not a typical use of a water balance in plant operation?

• A. To manage inflows, outflows, storage, and ensure adequate pressures and supply reliability.
• B. To determine the exact pH of finished water.
• C. To forecast daily treatment chemical usage.
• D. To plan maintenance windows.

Answer: (B)

A water balance is about tracking how much water is moving through the plant: inflows, outflows, storage, and how those volumes affect pressures and the ability to supply customers reliably. It’s a planning and control tool for ensuring there’s enough water, predicting storage levels, and guiding decisions like when to run or shut down equipment and how much chemical is needed based on expected flow. Determining the exact pH of finished water isn’t a function of the water balance because pH is a chemical property, not a volume accounting issue. You measure pH with sensors or lab tests to know acidity/alkalinity, and you use those results to adjust dosing or treatment steps. The balance tells you how much water you have and how it’s moving, not its chemical characteristics.
