The Orange County Sanitation District operates the third largest wastewater agency west of the Mississippi River. For over 50 years, we have safely collected, treated and disposed of and or reclaimed the wastewater generated by 2.5 million people living and working in central and northwestern Orange County. Each day we treat approximately 250 million gallons of wastewater enough water to fill Anaheim stadium nearly three times each day. About 80 percent of the wastewater comes from homes – sinks, toilets, showers, laundry, and dishwashers. The rest comes from businesses – retail stores, restaurants, manufactures, hotels, offices, and other industries.
We protect public health and the environment by providing effective wastewater collection, treatment, and recycling.
