After wastewater goes through primary and secondary treatment, it flows to our Advanced Water Purification Facility where a multi-barrier process separates water from pollutants. The state-of-the-art, four-step advanced purification process consisting of 1) ozone pre-treatment, 2) membrane filtration, 3) reverse osmosis, and 4) ultraviolet light with hydrogen peroxide. The product water is near-distilled-quality and is stabilized with minerals before its roughly 10-mile commute to the Seaside Groundwater Basin. At the Basin, it is injected into the aquifer where it naturally filters through sand and gravel to support the local drinking water supply.
