Demonstration Projects for Washington
- Title: Washington, Burnett: Risk Assessment, Washington
Description: In this project, 14 new onsite systems were installed and monitored on sites selected through a risk assessment process. Ten different secondary, advanced, and combinations of treatment systems and four less-than-secondary treatment systems were installed, operated and monitored for 3 years. System capital and operating costs indicated that large numbers of certain secondary and advanced onsite wastewater treatment systems are substantially higher than anticipated. It was also noted that true operating costs are difficult to quantify in such demonstration projects because of the changes they influence in normal attitudes toward their onsite wastewater systems
