To serve as a resource for small rural systems including tribes, Alaska Native Villages, and territories, EPA has developed a series of Web-based training modules on maintaining and operating small wastewater and drinking water treatment systems. This information is geared toward system operators and managers in Indian country, and could be of benefit to anyone operating and maintaining a small water or wastewater system.

The training modules are based on a series of 11 in-person training workshops that EPA held across the country for federally recognized tribes, Alaska Native Villages, and U.S. Territories in 2011-2012, which provided instruction on how best to operate, troubleshoot, and maintain small wastewater and drinking water systems. The workshops were funded through the American Recovery and Reinvestment Act of 2009.   

Operation and Maintenance Training Modules: 

Note: Do to the size of these files they take a minute or two to load.

  • Sewer System Overview (24.1MB) - This module provides an overview of the basic wastewater treatment process, from primary treatment to disinfection and sludge removal. The second half of the module focuses on maintenance of collection systems.
  • Mathematics Overview  (23.3MB) - This module provides an overview basic mathematics for water and wastewater operators preparing for a level one and level two operator certification exam, or as a general review of practical math applications.
  • Lift Station Overview (23.5MB) - This module focuses on all aspects of lift stations from pumps, to operation and maintenance, to emergency planning and troubleshooting.
  • Overview of Lagoon System Management (16.8MB) - This module focuses on wastewater lagoon functions (both aerobic and anaerobic), lagoon performance, sampling and analysis of lagoons, and operation and maintenance of lagoons.
  • Decentralized Wastewater Systems (20.5MB) - This module includes such topics as system inspection, system maintenance, and "things to avoid" for septic tanks. The module provides an overview of decentralized wastewater treatment and processes and includes a special look at innovative decentralized technologies and "best practices" for managing onsite systems.
  • Providing and Protecting Potable Water (38.2MB) - This module provides an overview of surface water systems, groundwater systems, and source water protection concepts.  Additional topics include: wellhead protection, sources and types of water contamination, and water treatment options.
  • Drinking Water Distribution System Management (25.1MB)- This module provides an overview of hydrant, pipe, and valve maintenance, and concludes with a special focus on corrosion and chlorine residual.
  • Storage Tank Management (19.5MB) - This module covers storage tank inspections and maintenance and provides safety information for both tasks.
  • Asset Management Overview (24.6MB) - How do you inventory and manage your water system or wastewater system assets?  This module covers asset management for long-term infrastructure stability and financial sustainability.
  • Techniques for Developing a Rate Structure (17.5MB)- This module covers the "how" and the "why" of developing rate structures that will fully support long-term utility operations.
  • Water and Wastewater Operation and Maintenance (O&M) Case Studies (13.6MB) - This module highlights lessons learned from: 1) accidental contamination of a water system, 2) chemical contamination at a water treatment plant, 3) sewerage collection overflow, and 4) operation of an "alternative" onsite wastewater system.
