AUGUSTA — Water will be shut off for several residents and businesses on Mount Vernon Avenue between Bond Brook Bridge and Bond Brook Road for about four hours Wednesday afternoon because of ongoing work on water services and mains.

Greater Augusta Utility District officials said the temporary water main shutdown is scheduled to last from 2 p.m. to approximately 6 p.m..

The shutdown is necessary, officials said, to install two 16-inch valves into the 16-inch water main running under the road. The work will connect all water services to the 16-inch main line.

The shutdown will not have an impact on all Mount Vernon Avenue customers, officials said. Those on an 8-inch water line are not part of Wednesday’s planned work. The work is part of a comprehensive construction project on Mount Vernon Avenue, including upgrading water and sewer pipes under the road, and, next summer, reconstruction of the road.

Before the shutdown, district officials encourage customers in the affected area to store a sufficient quantity of water for drinking, cooking, cleaning and sanitary needs.

After the shutdown, there is a possibility some customers in the area may see air or discoloration in their water. If they do, district officials advise them to flush cold water faucets for two to five minutes. If the water does not clear up after five minutes, customers are advised to call the district office at 622-3701 or, after 4 p.m., public safety dispatch at 626-2370.
