The City of Oceanside has broken ground on a new $67 million water purification project that positions the city to become the first in San Diego County to provide recycled drinking water by 2022.
The City says the Pure Water Oceanside project will purify recycled water to create a new, local source of high-quality drinking water that is clean, safe, drought-proof and environmentally sound. Once complete, the program will produce enough water to provide over 30% of the city’s water supply or 3 to 5 million gallons of water per day.
Most of Oceanside’s current water supply is imported and originates from hundreds of miles away at the Sacramento Bay Delta and Colorado River. A small portion of the city’s water supply is local and comes from a naturally occurring underground aquifer called the Mission Basin, but the aquifer’s water has declined over years of use. The City hopes the project will address a variety of challenges such as the rising costs associated with importing water or the fact that these supplies require an enormous amount of energy to transport and are vulnerable to natural disasters and earthquakes.
“Pure Water Oceanside marks the next big step for our City and a larger movement for the region as a whole to create sustainable water supplies in San Diego County. The project will safeguard against drought, reduce our dependence on increasingly expensive imported water, provide an environmentally friendly alternative to transporting water, and create an exceptionally pure drinking water supply,” said Cari Dale, Water Utilities Director, City of Oceanside.
To prepare the water for delivery to customers, the “future-focused” project will use a series of state-of-the-art purification steps that replicate and accelerate nature’s natural recycling process: microfiltration, reverse osmosis, ultraviolet light and advanced oxidation and mineral injection.
“This future-focused project will provide multiple benefits by reusing our water resources to their full potential,” said Dale.
