Californian officials have outlined plans for a 72km tunnel to boost water supplies and help the drought-stricken region combat climate change.
The US state’s Department of Water Resources published a draft environmental impact report detailing its proposals for the new pipeline in the delta region inland from San Francisco.
Under the plans, intake points would be built on the Sacremento River to the north of the Delta area then linked by a 12m-diameter tunnel to Bethany Reservoir further south.
Californian officials said the project was necessary to increase resilience to seismic risk, sea level rise and “other foreseeable consequences of climate change and extreme weather events”.
More than 97% of the state is currently in “severe drought” according to a national monitor, with over half its land suffering from “extreme drought” whereby fires start all year round and water is inadequate for livestock and wildlife.
