Residents Invited to Water Replenishment Celebration

Celebrate 50 years of innovative groundwater management on Saturday, September 8 from 9 a.m. to noon at the San Gabriel Coastal Spreading Grounds on Whittier Boulevard in Pico Rivera. A special ceremony will be held starting at 10 a.m.

Come learn more about the history and future of local groundwater at this fun, educational and bike-friendly event hosted by the Water Replenishment District of Southern California, the Sanitation Districts of Los Angeles County, the Los Angeles County Flood Control District and the City of Pico Rivera.

The San Gabriel and Rio Hondo Coastal Spreading Basins have been used to replenish local groundwater supplies since 1938. In 1962, the Whittier Narrows Water Reclamation Plant was built, becoming the first plant in the United States to replenish groundwater with treated wastewater.

Parking for the event will be available across the street behind the A Mi Hacienda Restaurant, 9613 Whittier Boulevard.  For more information, call 562.275.4215 or send an email to
