Removing nutrients from wastewater that goes into the bay could cost San Francisco up to $1.5 billion
Removing nutrients from the wastewater that flows from San Francisco sewage plants into the bay — which likely encouraged the growth of a massive algae bloom this summer — could cost up to $1.5 billion, according to the San Francisco Public Utilities Commission. The SFPUC reported its findings to the San Francisco Board of Supervisors Monday at a hearing to discuss how the city and county can address the impacts of wastewater in red tides that are expected to be more frequent with climate change, such as the algae bloom in August that killed tens of thousands of fish in the San Francisco Bay.
