Water: Septic (Onsite / Decentralized) Systems

Case Studies and Demonstration Projects

Case Studies

Case studies are useful for community planners, elected officials, health department staff, state officials, and interested citizens to explore what other communities are doing to effectively manage their decentralized wastewater infrastructure and find examples that fit their own unique needs. The following case studies contain examples of how local programs considered a wide variety of treatment technologies, from simple septic systems to advanced treatment clustered units, reflecting the specific management needs of the community.

Management Model 1: Homeowner Awareness

Many homeowner awareness programs are operating across the country. The most successful ones not only involve homeowners, but also support the homeowner in conducting maintenance (e.g., checking septic tank sludge levels). The following case studies review two such programs:

Management Model 2: Maintenance Contract

Management Model 2 targets areas at higher risk of environmental degradation due to higher system densities, more complex treatment technology maintenance, or other factors. The most effective Model two programs employ mechanisms to ensure that maintenance contracts are kept current and implemented properly. The following case studies review three of these programs:

Management Model 3: Operating Permits

Effective Management Model 3 programs often reward good system performance with extended permit renewal terms while requiring shorter permits and more frequent inspections for owners with poorly performing systems. The following case studies review four such programs:

Management Model 4: Responsible Management Entity (RME) Operation and Maintenance

RME Operation and Maintenance is best used in areas with high environmental risk and a need for professional oversight to ensure consistent system operation and maintenance. The following two case studies review programs that ensure that the RME has sufficient authority to conduct operation and maintenance activities that assure system performance:

Management Model 5: RME Ownership

Responsible Management Entity Ownership takes decentralized wastewater management to a high level of accountability. Under the model, the RME serves as owner and manager of the onsite wastewater systems. Instead of the homeowner, the management entity takes responsibility for operation and maintenance and for scheduling needed repairs or service. The following case studies review three of these programs:

319 Nonpoint Source Success Stories

The Section 319 Nonpoint Source Success Stories Web site features stories about nonpoint source-impaired waterbodies where restoration efforts have led to documented water quality improvements. A number of these success stories highlight management practices and rehabilitation of decentralized wastewater infrastructure that have led to improved water quality, including:

Title: Cluster Systems and Water Reuse in Mobile, Alabama
In Mobile, Alabama, untreated wastewater is removed from overloaded municipal sewers (known as 'sewer mining') for decentralized wastewater treatment and then reused to irrigate a city park. This project utilizes four different cluster decentralized technologies to determine performance and operational requirements. It also successfully demonstrates how decentralized alternatives can allow for the extension of overloaded municipal sewers. The Mobile Area Water and Sewer Systems (MAWSS) management of these low-cost sewer and cluster treatment facilities has enabled planned growth in areas east of the city.
