How could the new odor reduction system affect Santa Clara County?
Regional wastewater facility upgrade may improve environmental health in Santa Clara County. The $177 million dewatering facility, located at the San Jose-Santa Clara Regional Wastewater Facility, is designed to significantly reduce odors and improve the processing of sludge. By using centrifuges and an odor control system with carbon and ammonia scrubbers, the facility prevents foul air from wafting over to nearby communities. Furthermore, the decommissioning of the old drying beds offers a chance to convert that acreage back to open space along the bay, providing a regional environmental improvement that benefits the broader Santa Clara County area.

How it reaches Santa Clara County
-
San Jose completed a $177 million dewatering facility at the San Jose-Santa Clara Regional Wastewater Facility off Zanker Road. This facility uses centrifuges and an odor control system to process digested sludge. The process allows biosolids to be made ready for use as compost or fertilizer in a day, replacing a process that previously took up to four years in open-air lagoons.
The full event1independent outlet -
The new facility uses centrifuges and an odor control system to process digested sludge, making biosolids ready for use as compost or fertilizer in a day instead of years. This process reduces the foul air that previously wafted over to Alviso and Milpitas, while the decommissioning of the old drying beds allows for the conversion of acreage back to open space along the bay, benefiting the region governed by Santa Clara County.

Why it matters
The upgrade represents a major investment in regional sanitation infrastructure, addressing decades of environmental concerns related to sludge disposal in the South Bay. By moving away from open-air lagoons, the county reduces localized environmental risks and improves the quality of the surrounding bay area.
This project is part of a larger $1.2 billion investment by San Jose’s Environmental Services Department, which has completed 31 projects in the past decade. It aligns with broader regional efforts to modernize aging infrastructure and protect the environment for future generations.
