Rio Dell Wastewater Treatment Plant Upgrade

$12.9 million

Beginning in 2003 the City of Rio Dell began receiving Cease and Desist Orders from the State Regional Water Board for the facility’s non-compliance with the Water Quality Control Plan for the North Coast Region (Also known as the “Basin Plan”) limiting development in the City. In response the City upgraded the Wastewater Treatment Plant to a state-of-the-art Aeromod facility, in addition to creating a new effluent disposal field where wastewater could be discharged in a manner that complies with current environmental regulation. The projects were completed in 2013 and the City received a rescission of all related cease-and-desist orders on August 17, 2017.
