Frequently Asked Questions

Chatham County is joining forces with Sanford, Pittsboro, and Siler City to better meet the growing need for water and wastewater services in the region.

With the Chatham-Siler City Advanced Manufacturing (CAM) site, Wolfspeed, and many other expansions and developments on the horizon, the region’s water infrastructure is key to securing our community’s economic future. The merger of water utilities in the region ensures a more robust, interconnected system, which creates a more resilient and efficient water system.

This merger process officially took effect in 2024 when Sanford and Pittsboro joined forces to form TriRiver Water. Now, Chatham County and Siler City are joining up, making TriRiver Water a growing regional water utility.

TriRiver Water's name symbolizes the connection to the three rivers that sustain our region and reflects a continued commitment to innovation, sustainability, and community. It also embodies a dedication to improving quality of life by providing exceptional service to customers as the region grows.

Chatham County Water customers can expect a final water bill from Chatham County dated June 27, 2025.  Customers can begin making payments for the June 27 bill to TriRiver Water starting on July 8.

Important: The payment conversion process will begin on July 1 and end on July 7. Customers will be unable to make payments during this time.

Starting in August 2025, you will receive your first official water bill from TriRiver Water. 

Existing Chatham County Utilities utility customers will not be charged any transfer/rollover fees or be required to pay a new deposit during the TriRiver migration in July 2025. 

You can count on the same exceptional service you are accustomed to now. The only changes you’ll need to make on your end are who you make your payments to and where you send those payments.
