Because leaders across this drought-afflicted region all embraced the same innovative idea a decade ago, three separate sewage recycling systems will soon come online in Oceanside, East County and San Diego.
While drought was the main motivator for spending millions to purify sewage into drinking water, local leaders were also spurred by increasing costs for imported water and long-term concerns about the Colorado River.
Whatever the motivation, years of planning and construction are nearing separate finish lines for each of the three projects: Pure Water Oceanside, East County Advanced Water Purification and Pure Water San Diego.
Oceanside, which actually completed a small first phase of its sewage recycling in 2022, is slated to complete a major expansion by the end of this year to produce 6 million gallons of purified water per day.
East County Advanced Water Purification, a partnership between the city of El Cajon and multiple water districts, is scheduled to start producing 11.5 million gallons of purified drinking water sometime this fall.
And Pure Water San Diego, the largest and most expensive of the three systems, is slated to begin producing purified water in early 2027 and ramp up to 30 million gallons per day by the end of 2027.
