The new facility, located at the city’s wastewater treatment plant, will use large reverse-osmosis filters to create 6 million gallons of fresh water per day–about a third of the city’s needs–but with room for expansion.
The water plant proposal has been in the works since 2016. The agreement with the city’s lender, Bank of the West, will cover construction costs as the $64.6 million project gets underway next year at the location of the existing water treatment plant.
The almost $70 million project aims to develop a reliable, drought-resistant water supply so the city doesn’t have to depend so much on buying water and can use Sacramento-San Joaquin River Delta water year-round.
The state has agreed to pay Antioch $27 million in a settlement that guarantees the city’s 150-year old rights to pump water from the Sacramento-San Joaquin River Delta for the long term and will help pay for a planned desalination plant.
In return, the city will ditch a provision in a 1968 water rights deal that required the state to reimburse it for one-third of the cost to buy substitute water from the Contra Costa Water District when the Delta water gets too salty, which has been occurred more frequently in recent years.
Antioch to receive $27 million settlement from California’s Department of Water Resources – California
Antioch’s plan to build a long-awaited brackish desalination plant got a major boost this week when the City Council officially accepted a $10 million state grant that will pay toward design and construction.
The city’s grant was one of three statewide to be awarded in March 2018 from the Department of Water Resources for desalination projects under Proposition 1, but environmental reviews and other work still need to be done to free up the money.
