• Maximize use of existing infrastructure
CENTRAL SAN HAS A HISTORY OF
EMBRACING INNOVATION
• 1980s: Waste-to-Energy System
• 1997: Largest UV facility in the United States _ (_
• Early adopter of technologies
(e.g. closed-circuit television inspection of
sewers, SL-RAT, trenchless construction) �
• Central San empyloees take pride in
innovations and developing creative solutions
