LRV Credit is an online set of tools that assist regulators, water/sanitation authorities, and their consultants to manage the data from site-specific pathogen removal studies in wastewater treatment systems for the purposes of assigning log10 reduction value (LRV) credits for water reuse projects. LRV Credit's primary application is for studies of secondary and tertiary wastewater treatment processes, but it can also be used for advanced treatment and disinfection processes. The tools include a cost estimator, a data management system, and an LRV statistics calculator.

LRV Credit has been co-conceptualized and tested by water utilities representatives in the state of California, US.
