Free Autosamplers and Flow Meters

Last updated April 5, 2024

What We Offer

In 2022 and 2023, as part of the activities under our cooperative agreement with the U.S. CDC, WEF offered free automatic samplers and flow meters to territorial, tribal, and small wastewater utilities. A total of 287 autosamplers and 27 flow meters have been delivered so far. Although utilities were not required to participate in wastewater surveillance programs after receiving their autosampler (and flow meter, if requested), they were encouraged to consider doing so. WEF collaborated with the CDC to design these free offerings to address the fact that participation in wastewater surveillance has historically skewed toward larger, well-resourced utilities. We are pleased to announce that we are running a similar program in 2024.

Important Deadlines

If you are a utility serving a small, rural, tribal, or territorial community and interested in a free autosampler and flow meter, please find the 2024 utility invitation here. Although originally due on January 31, 2024, applications will continue to be accepted while autosampler and flow meter supplies last.
