Abstract

The current regulatory framework for potable reuse relies on the ability to grant treatment credits for the reduction of pathogens from wastewater by secondary, tertiary, and advanced treatment processes. In the past, secondary and tertiary treatment facilities sought credits based on historical pathogen datasets. However, the performance of treatment processes is highly variable and depends on many design, operational, and environmental factors. Thus, regulators are recommending site-specific studies. This project will provide guidance on the design and implementation of these studies. Research partner: California State Water Resources Control Board.
