The wastewater treatment process leaves a dry, earthy-smelling material called biosolids that makes a great soil amendment.

Class A Quality

The biosolids generated by Goleta Sanitary District are rated Class A by the US Environmental Protection Agency, making them a quality soil amendment. To maintain the Class A rating, the District processes the biosolids carefully and tests every batch for a wide range of contaminants.

Biosolids are Free

Biosolids are a key ingredient in many commercial soil amendments. Currently Biosolids are available on a first come first serve basis

Please note the following:

  • This material is not to be used as a top soil and it must be turned into your soil 
  • It is not recommended for use with root vegetables
  • Please bring your own small garbage bags or containers for transport, there is a shovel available for your convenience; we do not have any prepackaged amendment at this time.
  • Pick up days/hours are M-TH 8-4, Friday 8-3

Nutrient Components of Goleta Sanitary District Biosolids

Digester Gas

The District’s solids treatment anaerobic digesters generate digester gas in the process of decomposing organic materials. This gas is composed of about 60% methane, is highly flammable and has a high heat energy value. The gas is collected and used to heat the digesters used in the solids treatment process as well as to heat on-site buildings, thereby significantly reducing the District’s consumption of natural gas.

Reclaimed Water

Goleta Sanitary District produces high quality secondary treated water and discharges it safely into the ocean. By adding a third stage of treatment, a portion of the secondary treated water is raised to a higher quality level and becomes recycled water. The water is then pumped by Goleta Water District to customers for use on large landscapes such as golf courses and schools. Reclaimed water is also used to flush toilets in some of the most recently constructed larger buildings in Goleta.

Cooperative Project with Goleta Water District

Goleta Water District added a new recycled water pipeline to the treatment plant and the recycled water project was born. Together, the two Districts are collecting wastewater, treating it and recycling it for landscape irrigation, saving up to 300 million gallons of potable water each year for residents of Goleta.

A New Source of Water

Goleta Sanitary District's treatment process produces a supply of highly treated wastewater that was simply being discharged into the ocean. To take better advantage of this water, the Sanitary District added a new and sophisticated tertiary treatment process.

Recycled Water is Safe

Recycled water has been used safely in California for decades. Its use is carefully monitored by local, state and federal regulators. The District's sophisticated and proven treatment processes, along with our specially designed and built recycled water pipeline, delivers safely and efficiently recycled water under stringent user guidelines. 

Everyone Benefits from Recycled Water

All Goleta Valley residents benefit because recycled water releases precious and limited potable water supplies for use by everyone. Recycled water customers benefit by having a new and reliable supply of water that isn't affected by drought.
