Groundwater Treatment Plant

The Long Beach Water Department operates one of the most modern water treatment facilities in the world.  In fact, it is the largest groundwater treatment plant in the United States.  Coupled with four of the most advanced water quality laboratories, this combination helps explain why the City's high quality drinking water consistently meets or betters all Federal and State drinking water regulations.

Completed in 1997, the treatment plant has the capability to treat up to 62.5 million gallons of groundwater each day. 

In 2012, the treatment plant processed over 10.2 billion gallons of drinking water. Overall, more than 19.1 billion gallons of high-quality drinking water was delivered to the Long Beach community.
