SOUTH BEND, Ind.—The City of South Bend is conducting flow testing on public hydrants starting this week and lasting through the end of November.

The tests are being done to ensure the hydrants are working properly, the city said.

During the tests, there may be a temporary drop in water pressure and discolored water may run through faucets. If this happens, run three cold-water faucets at full stream until water runs clear, according to the city.

Data gathered from the tests will allow firefighters to know that there is enough water available when responding to an emergency.

The city will conduct the flow testing on all public hydrants over the next five years.
