Sources of Water for Orange CountySources 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

PROJECT GOALSLow Colored Water: Color from 265 CU to <5 CU

Better Quality (TDS of 300 mg/L)

7 million gal/day since 2002Cheaper than imported water

PROJECT COSTS & PAYBACK

• Well Drilling $2.8 million

• Treatment Plant $13.2 million

• Total $16.0 million

• Annual Savings $2.6 million/yr

• Payback 8.0 years

• Savings $9000/day

Wastewater Recycling at Industrial PlantWastewater 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

19

MBR / RO SystemMBR / 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 LineBottom 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

ConclusionsConclusions

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
