Please join us for a walking tour of the Orange County Groundwater Replenishment System (GWRS). The GWRS 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. The process produces high-quality water that exceeds all state and federal drinking water standards.


Operational since January 2008, this state-of-the-art water purification project can produce up to 70 million gallons (265,000 cubic meters) of high-quality water every day. This is enough water to meet the needs of nearly 600,000 residents in north and central Orange County, California.


DATE/TIME: Friday, April 19, 2013 from 10:00 a.m. to 12:00 p.m. (optional no-host lunch following tour)


COST: Free for members; $25.00 for non-members; and $10.00 for non-member students
