City of Aiken Conducts Hydrant Flow Testing Downtown

Tuesday, January 31, 2023

Effective Saturday, February 4, the City of Aiken Engineering and Utilities Department (COAE&U) will conduct hydrant flow testing in the downtown area. The hydrant testing process will begin at 6 AM on February 4.

Hydrant flushing is necessary to test the hydrants to ensure adequate water flow and pressure are available. Flushing also removes sediment from the pipes to maintain water clarity and quality.

Downtown testing will conclude on February 5, 2023. However, some hydrants may be intentionally left open to continue flushing water lines for approximately 24-48 hours. This additional flushing minimizes the impact on customer services and expedites a regular water flow in the system.

The public is asked not to tamper with any hydrants, as this will cause unnecessary interruption to and delay this critical service. COAE&U advises that during the hydrant flushing process, customers may experience water discoloration and/or fluctuations in water pressure. If a customer notices these water issues, COAE&U recommends running exterior faucets, baths/showers, and/or utility sinks for 15-20 minutes to help clear the lines on the customer side of the water meter. It is recommended to avoid washing clothes until the water clears. If discoloration persists after completing the recommended steps, please contact the City Water Treatment Plant at 803-642-7629 for assistance. This helpline is monitored 24 hours a day, seven days a week. A helpful resource for those experiencing water issues is available at

COAE&U conducts hydrant flow testing to ensure compliance with South Carolina Department of Health and Environmental Control water quality monitoring regulations.

Updates on the hydrant flushing can be found at and on social media @cityofaikenengineeringutilities and @cityofaikensc. A map of the downtown area is attached to this release and posted online.

The City of Aiken appreciates the public’s cooperation during this critical maintenance of the City’s water system. Please call 803-642-7629 to report any issues or concerns.
