Sources of Water for Orange County
• Groundwater (OCWD) provides up to
66% of the water used in North and
Central Orange County
– Groundwater is pumped from
wells to producers (Cities and
Agencies)
– Groundwater basin is recharged
by the Santa Ana River, rain
water, imported water and
recycled water

72 MGD OCWD WWTP for IPR and
Seawater Intrusion Barrier
• 72 mgd of treated water
• 14 Trains + 1 Standby
• 15700 spiral wound
elements
• 85% Recovery of

Wastewater Recycling at Industrial Plant
• Located in Escondido, California
• 8500 sq.ft restaurant and 1 acre
beer garden with on site brewery
• One of the fastest growing
breweries in America over the last
10 years
• Have one of largest rooftop solar
panel arrays in California
• BOD and TSS limits enforced by
City of Escondido required them to
build a treatment plant on site
18
MBR / RO System
• Solids and BOD levels undetectable
after RO
• Reduced wastewater discharge from
25,000 gpd to 10,000 gpd
• 30,000 gpd reused in plant
•Cooling tower make-up
•Boiler make-up
•Centrifuge, fermentation & storage tank
rinses
•Floor wash downs
•Bottle and keg rinses

Bottom Line
• Saved $442,000 in hauling fees
• Saved $114,000 in chemical
costs (polymer)
• Saved $34,000 in water usage
fees from water re-use
– 11 MG/year normally taken from City
water supply not needed
• Undisclosed amount in fines
from City
• Approx. $600,000/year total
savings in operating costs

Conclusions
Membrane technology is critical technology
for water sustainability in Southern CA
The growth of seawater desalting and
wastewater reclamation will be essential for
further commercial growth in our region
Support for and involvement in local
projects is strengthens provides jobs
Maintaining state-of-the-art capability is key
to further grow our export business
