El Estero Wastewater Treatment Plant

El Estero Wastewater Treatment Plant is committed to protecting our environment and public health and safety by maintaining an efficient and effective wastewater treatment facility.  

On average, each person in the City of Santa Barbara contributes 120 gallons of water per day (about 5 bath tubs full) to the wastewater system. Each house or business has a pipe that is connected to a network of underground pipes and pump stations, which carry the wastewater to El Estero Wastewater Treatment Plant (WWTP). At El Estero WWTP wastewater is cleaned using physical and biological processes.

El Estero is an 8 million gallons per day, Secondary Treatment Facility, equipped with a 4.3 million gallons per day Tertiary Treatment for recycled water. To ensure that the treatment process is effective, extensive water testing is conducted before, during and after treatment by the Water Resources Laboratory.
