What are the 3 stages of advanced treatment that occur at GWRS?
GWRS – new water you can count on The system takes highly treated wastewater that would have previously been discharged into the Pacific Ocean and purifies it using a three-step advanced treatment process consisting of microfiltration, reverse osmosis and ultraviolet light with hydrogen peroxide.
What is the groundwater replenishment system GWRS )?
Operational since January 2008, the Groundwater Replenishment System is a state-of-the-art water purification project that can produce up to 100 million gallons (379,000 cubic meters) of high-quality water every day.
How does the GWRS protect Orange County Groundwater?
Water treatment at Orange County’s GWR system Water at the existing plant is treated using advanced techniques consisting of microfiltration, reverse osmosis (RO) and ultraviolet (UV) disinfection with hydrogen peroxide.
What is the correct order for water purification at the Orange County water District?
After wastewater is treated at the Orange County Sanitation District, it flows to the GWRS where it undergoes a state-of-the-art purification process consisting of microfiltration, reverse osmosis, and ultraviolet light with hydrogen peroxide.
Is sewage and wastewater the same?
Sewage is the part of wastewater that is contaminated with feces or urine, but is often used to mean any wastewater.
What happens in the final stage of wastewater treatment?
Tertiary treatment (stage 3) Tertiary treatment, also known as polishing, disinfects water to the highest standards. This stage is necessary to produce water to specification, such as technical waters, and to treat wastewater for public water systems.
What are should be taken while replenishing the groundwater?
Sources of water for injection wells include treated wastewater, stormwater, and agricultural runoff. Municipal wastewater and industrial wastewater are suitable sources for replenishing groundwater by pumping through RO process units. These are only some options to replenish depleting groundwater.
How much water does Orange County Recycle?
250 billion gallons
Orange County’s focus on water recycling and efficiency The county’s groundwater replenishment system is the world’s largest water purification system for indirect potable reuse. Over 250 billion gallons of clean drinking water have been recycled.
What does the Ocwd use the groundwater basin for?
Water moves down from the surface into the groundwater basin to replenish the aquifer. OCWD helps nature move the water along with a system of pumps, pipelines, levees, and filters. OCWD monitors and protects water quality and quantity—always maintaining sustainable water levels in the basin.
Does Orange County use reclaimed water?

When the water goes through the GWRS it is highly treated through?
The GWRS takes highly treated wastewater that would have normally been discharged into the Pacific Ocean and purifies it using a three-step advanced treatment process consisting of microfiltration, reverse osmosis and ultraviolet light with hydrogen peroxide.
Where does sewer get water?
Sewage, also called wastewater, is the contaminated water from homes, schools, and businesses. It comes from toilets, showers, clothes washers, dishwashers, etc.
