This critical infrastructure project involves disconnecting old supply lines and may cause low water pressure or temporary shutoffs.

Columbia, SC – Residents along Trenholm Road are currently facing water service interruptions as Columbia Water undertakes a critical project to replace a 16-inch water main this week. The work entails disconnecting old supply lines and is scheduled to impact areas from Rockbridge Road to Lakecrest Drive, including all of Lakecrest Drive and parts of Arcadia Road and Rockbridge Road.
Throughout the course of the work, residents may encounter low water pressure or temporary shutoffs, primarily occurring during standard business hours. Columbia Water staff are working diligently to restore services as quickly as possible to minimize inconvenience.
A boil water advisory has been enacted for those living in affected areas. Customers are being advised to boil water used for drinking or cooking for a minimum of one minute. Moreover, if residents notice any discoloration in their water, they are instructed to let their taps run for a few minutes until the water clears.
The current phase of this major infrastructure project is expected to wrap up by the end of the week, with the full project slated for completion by mid-October. The City of Columbia will conduct a water main test shut down along Trenholm Road at 9 a.m. on July 14 to ensure that no residents remain connected to the old lines that are being disconnected. This project comes at an estimated cost of approximately $20 million and will cover the installation of about 17,000 feet of new pipes beneath North Trenholm Road.
The overarching aim of this project is to enhance water quality in the region and address recurring water leaks that have troubled the area. Construction will generally take place from Monday through Friday, between 9 a.m. and 4 p.m. To expedite the installation process and reduce traffic disruptions, multiple crews will be on-site during working hours.
Despite the potential for traffic interruptions, the construction is being managed effectively to maintain a steady flow. Main installations are occurring within the median of North Trenholm Road, and drivers are encouraged to consider alternative detour routes. Recommended detour routes include Willingham Drive and Atascadero Drive to access Forest Drive, and Lakeshore Drive for those traveling from the Rockbridge side.
After the new pipes have been installed, the South Carolina Department of Transportation (SCDOT) is scheduled to repave North Trenholm Road, further improving the infrastructure in the area.
