How is water treated?


Coagulation:  Alum and other chemicals are added to water to form tiny sticky particles called "floc" which attract the dirt particles.




Sedimentation:  The heavy particles (floc) settle to the bottom and clear water moves to filtration.




Filtration:  The water passes through filters that help to remove smaller particles.






Disinfection:  A small amount of chlorine is added to kill any bacteria or microorganisms that may be in the water.





Storage:  Water is placed in a closed tank or reservoir where it flows through pipes to homes and businesses in the community.







The Montecito Water District treats its water from Lake Cachuma at the City of Santa Barbara's Cater Treatment Plant and treats the water from Jameson Lake at the Bella Vista Treatment Plant.  The potable water is stored in ten reservoirs within the Montecito area, and range in capacity from .77 acre feet to 6.92 acre feet or 251,600 gallons to 2.3 million gallons.
