Decentralized Wastewater Infrastructure Challenges in the Alabama Black Belt January 27, 2022 By Margaret Decentralized Wastewater, Wastewater Alabama Black Belt 0 A quarter of Americans rely on decentralized wastewater systems, including septic tanks, because they are too far away from municipal sewers or the local environment cannot support a wastewater treatment plant. Decentralized wastewater treatment facilities can offer economic and environmental benefits to a community, but they can also be dangerous to public health and the local ecosystem if they are not designed properly. In the Black Belt region of Central Alabama, the rural landscape and heavy clay soils make it difficult to establish a traditional wastewater facility. These communities have struggled with wastewater management for years and the U.S. EPA (with many partners) has been working to help develop long-term solutions. Impermeable soil, high rates of poverty, and no sewer access can result in difficult choices. Some communities in this region use straight pipes to carry wastewater to a nearby location like a ditch or woods, where residents can then be exposed to raw sewage. Decentralized wastewater treatment systems can use a variety of different approaches to process a community’s wastewater, but there are also financial and managerial solutions that can be explored. Responsibilities can be better distributed and organized with community leadership. Individuals who attend community meetings and communicate with their state and local government officials are more likely to have their voice heard. The newly passed infrastructure bill is set to contribute $150 million in decentralized household grants over five years to help low-income homeowners construct or repair failing septic systems. Investments are also needed in cost-effective treatment technologies and innovative approaches to help municipal wastewater systems reach rural communities. Dig Deep, an organization that helps bring running water and adequate sanitation to communities across the United States, created a decentralized wastewater innovation cohort to help connect rural communities with innovative solutions. The Alabama Black Belt is just one of many regions of the United States that are struggling, with a history of environmental injustice compounding logistical challenges. Roughly 2.2 million Americans across the United States still do not have running water or adequate sanitation. The information in this blog post was presented at a U.S. EPA webinar in May 2021.
