Atlanta\u2019s watersheds occupy unique niches that demand special consideration.\u00a0 Downtown developments sit atop a watershed division that directs westerly runoff into the Chattahoochee River and ultimately into the Gulf of Mexico and easterly runoff into the Atlantic Ocean.\u00a0 Cumulatively, these watersheds impact hundreds of miles of aquatic waterways and two major marine bodies of water.<\/p>\n

Atlanta\u2014and many other major American cities\u2014rely on CSO\u2019s (combined sewer overflows) to handle both sewage and storm water runoff. \u00a0Unfortunately, when runoff from excessive precipitation overwhelms the system, untreated sewage spills out of effluent pipes.\u00a0 Normally, this pipe would channel discharge to a waste treatment plant and ultimately a tributary of the Chattahoochee River, but when flooding occurs, untreated sewage overwhelms the system.\u00a0\u00a0 Due to Atlanta\u2019s proximity to the Chattahoochee River and the adjacent, low-lying areas like Proctor Creek and English Avenue, communities have faced floods exposing their community members to many feet of flood water containing untreated sewage.<\/p>\n

In 1998, the City of Atlanta was sued by the State of Georgia and the United States of America for violation of the Clean Water Act.\u00a0 The resulting ordinance of 1999, known as the FACD (First Amended Consent Decree), required the city to (1) achieve full compliance with the NPDES (National Pollution Discharge Elimination System) emission levels for the WWTF\u2019s (Wastewater Treatment Facilities) effluent.\u00a0 These effective pollution permits allow for and monitor pollutants\u2014in this case nutrient loads\u2014into bodies of water.\u00a0 Additionally, compliance with GWQCA (Georgia Water Quality Control Act) and CWA (Clean Water Act) water quality of the downstream section of the Chattahoochee River must be upheld. (2) The city must eliminate all unpermitted discharges; and, (3) prevent all sanitary sewage overflows. These requirements were to be completed and upheld by 2014.<\/p>\n

Though the city of Atlanta implemented many projects, additional time and money were needed. In 2015, the city submitted an extension of the FACD to the federal government, which extended the projects\u2019 timelines and laid out a funding scheme.\u00a0 The federal government approved this document, known as the Atlanta Water and Wastewater Bond, Series 2015.\u00a0 The bond, worth $1,237,405,000, details Atlanta\u2019s CSO present and future actions to ensure proper emissions by 2027.<\/p>\n

According to the bond\u2019s outline, when the heaviest rain events occur, \u201cflow volumes can exceed the combined treatment capacities of [WWTF\u2019s].\u201d When this happens, \u201cfour individual CSO control facilities are brought online as needed to provide additional treatment capacity prior to discharge to their respective receiving streams\u201d (Wastewater Bond, 56).<\/p>\n

Again, all CSO and WRC\u2019s discharging into the Chattahoochee and South River basins must possess a NPDES permit, by federal law.\u00a0 This permit regulates acceptable levels of water quality degradation, particularly, dissolved Nitrogen and Phosphorous levels and fecal particulate matter.\u00a0 When left untreated, these pollutants can spread disease and damage waterways, thus impeding ecosystem services, reducing recreational fishing, and degrading drinking water.<\/p>\n

Shockingly, Atlanta\u2019s attempts to comply with federal pollution regulations do not protect its community members from physical inundation, disease, and impairment due to the design of CSO\u2019s.\u00a0 The city has and continues to invest billions of dollars to fortify CSO operations under federal compliance, but these actions keep community members at risk.\u00a0 The actual solution is to separate storm water drainage systems from sewage systems.\u00a0 This action would ensure the safety of tens of thousands of residents.<\/p>\n

The separating of wastewater and sewage infrastructure can be wildly expensive and cumbersome given the magnitude of construction needed in an urban environment.\u00a0 In the mid\u201990\u2019s, however, Bremerton, Oregon successfully implemented an alternative solution to outright pipe separation.\u00a0 The city achieved this through, \u201cpump station upgrades, treatment plant construction, storage and a major public involvement campaign\u201d (City of Bremerton, 2010).\u00a0 The price tag including litigation, design and construction totaled $50.3 million.\u00a0 A PDF summarizing the city\u2019s scheme can be found here<\/a>. For comparison, the city of Atlanta\u2019s 2018 fiscal budget approximates more than $10 billion (City of Atlanta, 2017).\u00a0 Thus far, the city\u2019s revamped watershed bond has funded improvements to CSO\u2019s, but has not created pump stations; therefore further construction may be required.<\/p>\n
