A railroad stop that became a suburb
Riverdale started as a railroad stop in 1886 and was incorporated in 1908. Its main roads are Georgia 85, Georgia 138 and Riverdale Road (Georgia 139), with Upper Riverdale Road running along the east side and Banks Park and Travon D. Wilson Memorial Park among its green spaces. The city had 15,129 residents in 2020, and ZIP 30274 is a good deal larger.
Housing age and what tends to break
The median home was built in 1990, and about a third were built before 1980. In that older third, original galvanized supply lines, worn gate valves and aging cast iron or clay drain pipe are more common, and a slow main drain often turns out to be a lateral problem rather than a clog. The 1990s and newer homes mostly need water heater replacements, fixture repairs and the occasional slab or yard leak.
How CCWA splits responsibility
CCWA serves all of Clayton County and its six cities. Its water comes mainly from the Little Cotton Indian Creek, Shoal Creek and Pates Creek watersheds, with the Flint River as a supplement. CCWA's service line runs from the main to the meter; the line from the meter to the house is the customer's. CCWA has finished a service line material inventory and offers a lookup portal so residents can see what their own line is recorded as. Its annual water quality report covers testing.
Backflow works differently here than in most of the metro. CCWA installs backflow devices at customer connections and sends its own state-certified specialists to test them every year, timed around meter reading. Homeowners do not need to hire a tester.
Gas safety
Clayton County has no city gas systems; residents pick a certified marketer, and Atlanta Gas Light runs the pipes. If you smell gas, leave the house first, then call 911 and AGL from outside.
Riverdale versus Atlanta, and calling
An Atlanta homeowner calls the city's Watershed Management department for water and the city's Office of Buildings for permits. In Riverdale those roles belong to CCWA and the City of Riverdale. Call the number on this page, explain the problem, and you will be connected with an independent plumber who works in Riverdale. Pricing and arrival are arranged between you and the plumber.
