Blackjack Mountain Water Tank Removal Project

Starting in late November/early December CCMWA will begin a water tank removal project at 1660 Barnes Mill Road in Marietta.

The Blackjack Mountain Water tank is almost 60 years old and has been out of use for the last few years. As a safety precaution, we have decided to remove it as the other tank onsite will be sufficient to meet the system's needs. Removal of the Blackjack Mountain water tank is expected to last a couple of months.

This work will affect traffic in the vicinity of the location on Barnes Mill Road. Periodic road closures will be necessary so that trucks can safely enter and exit the site. Flaggers will be on hand to guide traffic during these times.

Work hours: Monday - Saturday, 8:00 a.m.-5:00 p.m.

Hours for Periodic Road Closures - 9:00 a.m.-4:00 p.m.
