Marietta's water picture
The Cobb County seat around Marietta Square runs its own utility. Marietta Water, part of Marietta Power and Water, buys treated water from the Cobb County-Marietta Water Authority, which draws from the Chattahoochee River and Lake Allatoona, and distributes it across the city. It also handles sewer. Its service and maintenance dispatch line, 770-794-5230, is answered at all hours.
Not every Marietta address is on Marietta Water. Homes with a Marietta mailing address outside city limits may be on Cobb County Water System instead, so check your water bill before calling about a leak at the street.
The median home was built in 1987, and about a third of houses predate 1980. Older neighborhoods near the Square are where tired valves, aging supply lines and older drain piping most often cause trouble. Marietta Water handles lead service line removal on its side, while homeowners are responsible for any lead materials in their own plumbing.

Seasonal notes
Cold snaps split pipes in crawl spaces and on outside walls, especially in older houses. Holiday meals send grease into drains and sewer laterals. Summer storms can flood low crawl spaces where a sump pump has failed. City permits for repairs and replacements come from Marietta Building Inspections, which lists plumbing among its most requested permits. Ask the plumber about after-hours pricing when you are connected; nights and weekends usually cost more. Arrival depends on the time and the plumber's workload, so no specific time is promised.
