Regularly scheduled changes known as a system burnout will happen for some TriRiver Water customers in Chatham County in February. 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 customers in the Chatham County North District on Monday, February 2, 2026 and resume adding ammonia to the disinfection process on Monday, March 2, 2026. (The rest of the TriRiver Water system will do its burnout in March.)
TriRiver Water will also use this time to flush the water mains throughout the system to remove sediment in the lines and refresh the entire distribution system. So you may notice our crews releasing water from fire hydrants in your neighborhood.
While this process is underway, 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.
