Regularly scheduled changes known as a system burnout will happen in March for most TriRiver Water customers. The process could result in temporary changes to your water’s taste, smell and clarity.
For 11 months out of the year, TriRiver Water uses a combination of chlorine and ammonia (known as chloramines) as the primary disinfectant for the water supply. The North Carolina Division of Water Resources recommends public water systems that use chloramines switch to just chlorine for 1 month each year to maintain the highest water quality.
TriRiver Water will stop adding ammonia to the water (for all areas except Chatham County North District) on Sunday, March 1, 2026. Ammonia will return to the disinfection process on Wednesday, April 1, 2026.
TriRiver Water will use this month without ammonia to flush the water mains throughout the system. This is regular maintenance that helps remove sediment in the lines and refresh the entire distribution system.
During this time, you may notice your water smells or tastes different. It could also be discolored. Rest assured, your water is still safe. There are no associated health risks with this standard process.
If you notice discoloration at your tap, allowing the water to run for 5-10 minutes should clear it up.
Some aquatic pets can have specific habitat needs affected by this process. If you are unsure, contact your local pet store to determine if this process could affect your pet.
