Pure Water Oceanside to Start Purifying Recycled Water by End of ’21

By the end of December, the city will begin turning recycled water into drinkable water through its new, state-of-the-art water purification facility, the first of its kind in San Diego County.

The new water purification system, dubbed Pure Water Oceanside, uses ultrafiltration, reverse osmosis and an advanced oxidation process to purify recycled wastewater.

“It’s inspired by the natural water cycle and is the natural next step for recycling our precious water resource that we currently discharge into the ocean without tapping into its full potential,” said Oceanside Water Utilities Director Cari Dale, who has led the project.
