Torrential rain in late March caused two more major raw sewage spills into the Chattahoochee River in Roswell, bringing the total to more than 2 million gallons this year. That’s enough to fill nearly four Olympic-size pools.
Fulton County reported overflows of 286,187 gallons on March 27 and 840,576 gallons on March 29. State environmental regulators are still calculating fines for two earlier spills that totaled 981,000 gallons.
Fulton is spending about $40 million to stop the overflows by fixing a leaky pipe and upgrading pump stations and a sewage-treatment plant. The work should be finished by the end of 2012, county officials said.
The spills occur when rain swells the river, causing it to top its banks at Riverside Park along Azalea Drive. Water inundates the pipe and pump station carrying sewage from Alpharetta, Johns Creek and Roswell.
