What You Flush is Helping Track Coronavirus

06/01/2020 We have teamed up with BioBot, a company out of Massachusetts that has been testing influent(raw) wastewater nationwide for Covid-19.  We signed up in early April to get on the limited list and we were accepted at the end of April for testing.  We have results back from two of the four weeks tested, the first two weeks in May, with no SARS-CoV-2 virus detected in the sewage at Nehalem Bay Wastewater Agency.  Our service area includes the communities of Nehalem, Manzanita, Wheeler, and Neah-Kah-Nie.

NBWA Informational Brochure

Established in 1970, the Nehalem Bay Wastewater Agency serves the Oregon coastal cities of Nehalem, Manzanita and Wheeler and the surrounding area.

Our main office is in Nehalem, but you might not know that those little buildings in the area are our major pump stations, nineteen and twelve building lift stations.

Of course, there are also 1145 manholes/clean-outs and 396,000 feet of gravity pipeline that varies in size from 6 inch to 21 inch that connects everything.
