Dye testing in sewer systems is used to determine what?

• A. Blockage location
• B. pH level
• C. Temperature
• D. Flow rate

Answer: (D)

Dye testing uses a tracer to watch how wastewater flows through the sewer. By introducing a colored dye at one point and observing its arrival at another point, you can see how fast the sewage moves between those locations. That travel time is what lets you estimate the flow rate (or velocity) in that part of the system. The test isn’t used to measure pH or temperature, and while dye movement can reveal unusual flow paths or potential blockages, its main purpose in this context is assessing how quickly the wastewater is moving.
