According to the United States Environmental Protection Agency (EPA), water reuse, also known as water recycling or reclamation, is the process of capturing waste water from various sources, treating it, and then using it for beneficial purposes such as agriculture, landscape irrigation, industrial processes, and replenishing a groundwater basin (aquifer recharge).

A Brief History of Water Reuse in Santa Barbara

Santa Barbara has a history of facing water shortages and has been a pioneer in water reuse to mitigate these problems. The practice took a significant leap forward following the severe drought in the late 1980s and early 1990s, which resulted in the implementation of the City’s Reclaimed Water System in 1989. This system treats wastewater to a tertiary level, making it suitable for non-potable applications.

Methods of Water Reuse in Santa Barbara

Santa Barbara has employed various methods for reusing water. Let’s delve into some of the key techniques:

Tertiary Treatment

Tertiary treatment, also known as advanced wastewater treatment, is the process where wastewater undergoes several stages to remove contaminants. These stages often include:

• Coagulation and Flocculation: This stage involves adding chemicals to the water that bind with contaminants so that they can be more easily removed.
• Sedimentation: Following coagulation, the water is allowed to settle, letting the larger particles sink to the bottom.
• Filtration: The clear water on top is passed through filters of varying compositions and sizes to remove suspended particles.
• Disinfection: Finally, the water is disinfected using methods like chlorination or ultraviolet disinfection to kill any remaining microorganisms.

Reclaimed Water for Irrigation

Reclaimed water from Santa Barbara’s wastewater treatment facilities is used extensively for irrigation, serving many public spaces, golf courses, and schools. This approach significantly reduces the demand for potable water in landscaping applications.

Indirect Potable Reuse

This process involves introducing reclaimed water into groundwater aquifers or surface water reservoirs (a process termed “aquifer recharge”) before the water is treated again to become potable. Santa Barbara has been exploring this technique as a way to sustainably augment its drinking water sources.

Onsite Systems

Santa Barbara encourages the use of onsite greywater recycling systems for residential landscapes. Greywater, which is waste water from sinks, washing machines, and showers, is treated on a smaller scale and then reused for landscape irrigation.
