Key Components of California WaterFix
California WaterFix, described in the EIR/EIS as Alternative 4A, has three key components.
First, the project calls for three new intakes in the north Delta where the water quality is higher and impacts to fish are reduced.
Second, it includes two new tunnels, located up to 150 feet below ground, to transport water. These gravity-fed tunnels would protect the water supply from salt water intrusion due to sea level rise, levee failure and earthquakes.
Third, improved state and federal pumping facilities in the south Delta reduce environmental and construction impacts.
The final project has been refined from what state and federal agencies had originally proposed to better protect wildlife, fisheries and habitat.
California WaterFix is a modernized water delivery system designed to provide a reliable water supply while protecting Delta flows for water quality and fish.
