"I've worked with more than 10 plants in Southern California and haven't seen such an old plant remaining in 2014," says Kishora Panda, the site's process engineer. In 2013, two aged 24-in. mains running under the plant's foundation slab cracked. But $100 million in upgrades are allotted over the next 10 years to bring the system up to date. Scheduled tasks include replacing the aging pipes, pumps and headworks screening system, Panda says.
