Advanced Septic System Nitrogen Sensor Challenge Phase II: Prototype Testing

The Challenge

EPA selected Battelle Memorial Institute (Battelle) to support the Prototype Testing Program and the development of a Test/Quality Assurance Plan (T/QAP) and Verification Plan and oversee the testing of the sensors. The T/QAP will be based on the International Organization for Standardization Environmental Technology Verification (ETV) Standard - ISO 14034. Funding for the testing program is from the US EPA Office of Research and Development and the Office of Water/Wastewater Management.

Sensor testing will be completed at the Massachusetts Alternative Septic System Test Center (MASSTC), a National Sanitation Foundation (NSF) certified test facility in Barnstable, Massachusetts in 2018. Developers whose sensors are judged to be capable of meeting minimum performance goals during the one-week long preliminary screening will be invited to participate in an extensive 6-month field performance test. Battelle will verify the results of the field performance tests based on the VerifiGlobal Performance Verification Protocol and the requirements of the ISO 14034 ETV standard.

Sensor Performance Goals

Prize: Verification Report and 2019 Market Stimulation Opportunity

Following the release of the verification reports in early 2019, an external technical panel and The Nature Conservancy (TNC) will review the results. TNC and others are seeking funding for an order of 200 units, not to exceed a total cost of $300,000. The order would be presented in the summer of 2019 to the best performing sensor/s that completes the 6-month field performance test and meets or exceeds the performance goals.
