Mystic -- The Aquarion Water Co. has announced it will clean water mains beginning Sunday night and lasting through April 28.

During the project, the company said customers may notice drops in water pressure and some discoloration in their water. This discoloration results from the temporary disturbance of the water flow, which stirs up naturally occurring minerals that settle in water mains. Aquarion recommends customers store tap water in their refrigerators for drinking and cooking. Customers should also refrain from washing laundry if water is discolored. Before resuming use, customers should run their cold-water faucets until the water appears clear.

The streets that will be affected during the first week of the water main cleaning project are listed below.

Sunday, 9 p.m. to 5 a.m.: Camp Ground Road (45), Clara Drive, Coogan Boulevard, Greenmanville Ave. (168-251), Hendel Drive, Jerry Browne Road, Lantern Hill Road (1-277), Laura Avenue, Linda Avenue, Main Street (3-68), Maritime Drive, Marjorie Street, Michelle Lane, Mill Street, North Stonington Road (21-54), New London Turnpike (33-46), Olde Mistick Village, Pequotsepos Road, Stonington Road (13-73), Whitehall Avenue, Whitehall Landing, and Whitehall Pond
